Dear Mr. Harley,
I've been thinking about the fact that Spectral amps REQUIRE the use of MIT cables with their network box, and it suddenly dawned on me that the (passive) electronics in the MIT box could have been made part of the amp. This could have made the amp independent of specific cables, and the electronics could have been improved, possibly by using active components and/or changing the amp itself, to minimize phase shifts, delays and whatever other distortions introduced by an additional passive network in the critical path.
Then I thought of possible reasons why NOT to do it.
The amps currently have a feature that seems VERY impressive -- frequency response up to 150 KHz within 0.1 dB and to 1 MHz within 1 dB. However, this impressive feature is plainly unacceptable to speakers, so that the network is REQUIRED. However, how can we retain this special, unique, impressive, marketing-differentiator feature and still have the network? Simple: Separate the network from the amp, but REQUIRE that the network be used! Brilliant, isn't it? Especially when people have to buy our own cables and will be willing to pay extra for our network!
This way the amp can be as purist as can be, have the best measurement and so on, only that what you measure and what you hear may not be directly related…!!!
Maybe that's why Spectral avoid specifying anything about the output of the amps except power, as any output impedance and damping factor specs might be an obvious lie.
All this does NOT imply whether the sound of Spectral amps is great or not. I know you consider the DMA-360 a class of its own, and the above does NOT refute that.
Can you help me untangle these thoughts, in case I got anything wrong?
Thanks and best regards,
Amir
I have to say, anyone who has followed Spectral through the years knows that they are essentially incompetent at marketing - and proud of that incompetence, too. The rationale behind moving the output inductor from the amp to the speaker end of the cable is simply to help take the cable out of the equation - to incorporate the cable into the amplification system. It's an unusual and extreme approach, but their entire technical approach is quite unusual and extreme, and very focused on optimizing the entire electronics chain as a system.
The published frequency response specs, as Spectral themselves say, are not especially interesting in and of themselves, but more as a by-product of circuit designs with extremely fast recovery under transient conditions.
BTW, Spectral amps can be ordered as "universal" models, with more conventional input and output protection that allows use with any cable designs, at the expense of what Spectral considers the best sound quality.
Dear ScottB,
Thank you for your comments!
Spectral's alleged incompetence at marketing and pride of it MIGHT be misleading. Maybe they're smarter than they look… :-) In any case, these are only interpretations.
I see 3 main components involved - the amp, the network/box/inductor, whatever you choose to call it, and the cable (which to can subdivide to connectors, wires, shielding, soldering etc.)
What I still don't understand is why the network has not been incorporated into the amp, with proper shielding, if required. I fail to see why this would have provided worse sound, at least if the same cable, without the box in the middle (with more soldering and contacts), had been used. It could still be "very focused on optimizing the entire electronics chain as a system", actually more of the entire system… :-)
I wish Spectral had explained all of this in their site, in the descriptions of the DMA-250/360, including the sentence "Spectral amplifiers are not warranted for use with speaker cables other than MIT" (which appears only in the cables' description), as well as the existence of the "Universal" models, which I failed to see.
Actually, I also failed to locate any "Contact Us" in the Spectral site. It would be much better is I could contact the designers directly instead of openly posting possibly damaging thoughts :-(
Maybe RH has some access to them… Mr. Harley?
Best Regards!

do spectrals work with other speaker cables with networks, most notably with transparents?
Hello, dear Mcduman!
If you enter http://www.spectralaudio.com/, press "Spectral Audio System" and then "MH-750 Ultralinear Terminator", you'll see "Spectral amplifiers are not warranted for use with speaker cables other than MIT", so that even if the amps happen to work (possibly with some loss in sound quality), they'll not be covered by the warrenty.
Enjoy!
Amir
P.S., And I forgot to mention the risk to your speakers, which will also not be covered by any warranty... :-)
See my post on 15 USC 2302(c), below.
" do spectrals work with other speaker cables with networks, most notably with transparents?"
Yes!!!!!!!!!!!! Again, refer to the TAS/HP review on the Spectral website.

Dear mcduman,
God is considered more supportive and generous in some religions than in others, but believers usually stick to him (her?:-) at all costs.
God HP may give you all the moral support you'll ever need for using non-MIT cables, saving you money and saving you the overhead of selling your old cables, and providing you with sonic nirvana.
In the meantime, Spectral will only void the warranty (the abovementioned marketing coup? :-)
If nothing happens, you're more than fine.
In the low-probability case anything goes wrong, with the amps and/or speakers, I'm afraid God HP won't be generous enough to cover the costs.
This does not necessarily mean you're screwed -- you might be able to cheat your way out and say you HAVE been using MIT cables (hoping Spectral won't require sending the cables, at the pretext of having to check the network…)
After all, it's a world of apparently free choice, even under the threats of hell and promises of heaven.
YOU choose :-)
In any case, enjoy, whatever your choice!
Amir
i find this whole spectral thing very intriguing amir.
I am familiar with transparent cables, the only other option with a spectral amp as I understand though not a direct replacement for mit, and can easily attest to the superiority of the custom-calibrated, impedance-matched cabling systems with network boxes. If you ask me, they should be the next thing in audio as they make perfect sense from a synergy point of view
Now, if spectral wants to sell their amps complete with mit cabling and you have a sound in a class by itself, as some call it, then I have no problem with their approach because I already understand the advantages of custom calibration from my transparent mm2.
But you definitely have a point. I think history will remember spectral with their odd marketing strategies rather than their good sound.
Dear mcduma,
I have no real objection or problem or any moralistic issue with openly declaring that Spectral amps and MIT cables must be considered an integrated unit and that the amps must not be used with other cables.
My personal issues with this are:
* The fact is not stated loud-and-clear everywhere. It's "hidden" in the cables'
descriptions, but not mentioned in the amps' descriptions, including the "small"
issue of losing the warranty if other cables are used.
* If there are indeed "universal" models, as the many rumors say, why isn't it
published openly, alongside Spectral's preference of the MIT-specific models?
The corresponding models can then be reviewed and compared, verifying or
disputing Spectral's own preferences.
* I don't really understand (my problem) why the network needs to be in the middle
of (any) cable instead of part of the amp. I don't have any issue with
preferring the MIT cabling materials, connectors etc., regardless of network, so that
the total result would end up like with the terminated MITs, plus the ability to try out
and use other cables, without loss of the warranty.
I assume that "history" remembers nothing, it all comprises of people's memories, especially those that have them written and published :-) Not that what remains in the collective memory matters to ME that much... :-) Me - I want to have the best sound for myself NOW, not bothering what future people (including myself) might think when looking back.. :-)
As to "the only other option with a spectral amp as I understand": it might be an
option SOUND-WISE, but I'm not sure that's really an option WARRANTY-WISE…
Enjoy!
Amir
A couple of comments...as someone who has owned an entire Spectral system...with MIT cables:
It is truly in the top league of anything out there...excellent sound, performance
I don't think you can buy Spectral from a dealer who isn't well versed in the NEED for MIT cables...not to mention the sound quality. As to building in the network in the amp...to me there would be several concerns:
It would be a real pain to ship back an amp just to update the speaker cable portion of the amp....notice how much more frequently MIT updates/modifies/improves their cables than Spectral does the amps.
As I recall MIT cables are made to a given length...(aside from the tails)...and again it would be a burden to return the amp to spectral simply to permit me to change speaker placement...perhaps exceeding the length of cables....to match the network to the new distance.
After I sold my DMC 30 and DMA 150 the guy used some other speaker cables....a problem occured (no idea if it was related to speaker wires or not...or an act of God)...he returned the amp for service and they told him that amp was damaged due to high frequency oscillation....so there were able to correlate some type of amp problems to cables
I have not found Transparent cables to offer superior performance....particular over the equivalent MIT model (presently I don't use either MIT or Transparent...but I am curious about MIT's newest models
Just my thoughts
John
No doubt -- an act of God :-)
Thank you for your comments!
Amir
There's absolutely no question in my mind that Spectral would never do anything for marketing reasons. Of all the high-end audio manufacturers I've known over the past 20 years, none is as committed to pure sound quality as Spectral. The demand for their gear far exceeds their ability to manufacture. Moreover, Spectral Founder Rick Fryer's statement in my interview with him and Keith Johnson (Issue 190) that "We've had a tremendous luxury in not worrying about short-term profitablity" is an understatement.
Spend some time with an all-Spectral system and you'll understand their approach. There's no substitute for first-hand listening.
Dear Mr. Harley,
Thank you for your response! I'll henceforth give up any conspiracy theories regarding this :-)
However, there are a few specific issues you might help me understand, if you can spare the time, from your own prior knowledge and/or Spectral's help, if you have access to them:
#1. What is the electronic/physical reason for putting the network in the middle of a cable
instead of incorporating it into the amp itself, with proper shielding, if required?
#2. Are there indeed "universal" models to the DMA-250 and/or the DMA/360, as the many rumors say?
If yes, how do they compare to the "standard" (MIT-dependent) models?
#3. Why are important facts, such as issue of losing the warranty if other cables are used
and/or the existence of "universal" models, not stated very clearly in the DMA-250/360 descriptions?
(The warrant issue is "hidden" in the cables' descriptions)
Thank you very much!
Amir

Oops, I haven't read the quoted law in any depth, only the preceding text by BillK ("illegal to tie the use of a product to a specific alternate product"), and I thought it had been quoted in reference to tying SundayNiagara to Viagra and/or "North, north America, upper US!" to "Niagara"… :-)
Well, if anybody is willing to gamble his/her money by buying Spectral amps, using non-MIT cables and then, upon requiring any warranty services, suing Spectral, may s/he be blessed for his/her guts/stupidity. It might be a good way to legally extort money from Spectral, affordable mostly to whoever is him/herself a lawyer, while all that time his/her sound system may be inactivated. Good life!
While "Rick Fryer's insistence on using MIT cables" [might be] "bull", the warranty issue might be very real, possibly requiring a lot of overhead, heartache and nerves. Not for me: I like to enjoy music without having to worry about the consquences of my equipment choices... :-)

Dear Mr. Kessner,
Are you involved in the Audio Business and if so how?
Mark,
I do believe in a systematic approach to audio and in that regard have no issue with Spectral becasue if you don't want the cables then don't buy the gear. I think that there are too many "fruit salad" systems that people make and never have a satisfactory result let alone a great one.
My issue when we were a dealer is being told what speakers are "acceptable" to them sonically. I was in a market area where I could not have one of their choices and the other one could only provide me with maybe one pair a year, this is not a choice for a business. Show a 100k system that you can not duplicate for a client. I believe there are certainly more than two speakers that are good!!!!!!
The "soup nazi" memoranda for Spectral dealers did not fit me or my store.
So Mark "NO SOUP FOR YOU"either!

I'm afraid the only way I am "involved in the Audio Business" is by having spent all too much money on equipment (and discs :-)

Whaddaya think folks, does this constitue an apology, notwithstanding the concescending attitude?

No, it's NOT an apology. I simply let you know that, on my side, I gave up any grudge I've held against you, in spite of your ongoing rudeness and language.
Unlike you, I won't call for others' help as to who "owes" an apology to whom and why. If you wish to apologize, it's in your discretion, though I'm sure you think, as always, that you're right and others (RH and Spectral included) are wrong (and/or just bad).

Spectral's insistence on using MIT cables is like Microsoft blocking other browsers and forcing one to only use Internet Explorer.
The tiny difference being that Microsoft almost "owns" the market -- almost all PC owners use Microsoft operating systems (regardless of browser choice), and have little choice if they wish to use other Microsoft programs -- whereas Spectral is just a tiny manufacturer out of many, and users have PLENTY of choice.
If Spectral believes their amps work best with MIT cables and the amps and speakers are at risk without MIT cables, then it can be validly considered their moral choice not to warrant (promise to cover expenses for) their amps when used otherwise, possibly preventing customers from damaging their speakers.
One can dispute their beliefs (e.g., say other cables sound better and/or there is no risk), but, as long this is what Spectral believe, it can be considered their right.
Amir
Amir, I am not sure that you are correct with your assumption regarding Spectral and warranty items.
THey can certainly suggest and reccomend whatever they choose however if the goods are sold without a disclamer that is signed by the buyer in advance I doubt that this warranty issuewould stand up in a any court. I am not a lawyer , but do play one on TV, and I don't think that any audio product would pass that test. It can not be in small print or done in passing verbally either IMHO.
I do not find any issue with them designing the products the way they do. They are different in impedance and bandwidth than most components and for them it may be their "secret" ingredient so if this is needed to get the product to proform then the cable may be an integral part of the chain. If this is in fact correct and the units "will not" work without it then it is their obligation to have a warning label on the gear, the box and stamped on the dealers foreheads before one buys it.
Dear Elliot,
I apologize -- I must have been unclear.
It's not that I think Spectral's voiding the warranty when using non-MIT cables would stand up in any court. I believe that most probably it wouldn't, especially given BillK's quotation (www.law.cornell.edu/uscode/15/2302.html).
The (low-probability) case I discussed was:
* buying Spectral amps
* using non-MIT cables
* requiring any warranty services (i.e., something goes wrong, especially when the amps/speakers stop working
and one is left without good-sounding music).
In such a case, would one want to start legal procedures against Spectral, and wait until this reaches court?
If one is not a lawyer him/herself, the legal procedures may cost him/her a fortune, and, in any case,
a couple of nerve-wrecking years before s/he sees his/her money back and amps/speakers working again.
That's my entire point, and I'm not sure about it either, not being a lawyer myself.
Personally, I'm not sure I would like to take such a gamble, especially at the sums involved.
I hope the point is clearer now. In any case, it's quite a far fetched and low probability scenario.
Best regards,
Amir
Dear Amir,
I am clear and to be frank I don't think this whole thing is a big deal because if you don't like the car why worry about the tires.
I truely wish more people looked at audio as a system approach like Meridian, Spectral and some others so that the end users would get a quality and consistent end result. I feel that two many audiophiles want to think they know a whole lot more than they do and the result of the miss-matching is very expensive mediocrity.
I am not saying that doing yourslef can't work but it is hard. If one buys amp and preamp from one company you can be sure they work properly together and if you like the sound then you are way ahead of the game. We know that Spectral works with Spectral, and ARC works with ARC, and Krell works with Krell etc.etc. this is a "GOOD" thing! Cables which are filters all react with the gear they are hooked up with and some guidance when doing this is good however most companies avoid the frey so as not to cause poilitcal issues. Spectral likes to get its point accross and that is good but how they do it leaves a lot to be desired. Expertise is wonderful arrogance is not.

Chutzpah - unmitigated gall! It's a big bed, isn't it?
Dear Elliot,
I wish things were as simple as you picture them... :-(
First, if only I could tell whether I like the car before worrying about the tires... :-)
I live in a small country where there are few hi-end shops and fewer that keep top-of-line models in display/stock. There is no Spectral distributor here, so I can't audition their equipment. MAYBE, if/when I go abroad, I might find a Spectral dealer with DMA-250/360 and see if I like the car. (Actually, with the current economy, I could not audition the B&W 800Ds even in Japan, only the 802Ds, and I had to practically GAMBLE about almost 100% addition in price as to whether to buy the 802Ds or jump to the 800Ds.)
Second, hi-end cables are hardly like tires, at least as regards the costs of buying new ones and the loss (and overhead/effort) of selling the old ones...
Third, I hardly consider myself one of those who "think they know a whole lot more than they do". I have few sources of knowledge, little more than local dealers' advice and published reviews. This is the first time I ever ventured asking an audio critic (RH) directly.
Fourth, I have often "looked at audio as a system approach". In the old days it was all Yamaha, then Krell, later all Bel Canto and now all the system is EMM Labs, except for power amp(s), which EMM Labs have not issued yet.
Fifth, please also note that one rarely replaces multiple components at one go, most often it's one component at a time. Except for first-time buyers, one doesn't get an entire system by the same manufacturer at once.
I consulted the local dealer I work with (from whom I bought all my equipment except the B&Ws, which have another, exclusive distributor). The guy is all very experienced, knowledgeable and reliable (not a common phenomenon), and has known me and my taste for years. He was the one to suggest Spectral, of whom he is not a dealer, and does not usually have business with. He heard my system, listened to what I liked about it and what less, and suggested the DMA-360, which he knows very well (as well as the 250). He says they are very fast, with superb bass control, very wide soundstage, and their mids/highs can compete successfully the Hurricanes, which are great in that area.
I even considered buying Classe CA-M400 power amps, even if they may not have a high-endish reputation, but at least I know they are used, along EMM Labs players and preamp and B&W loudspeakers (e.g., my 800Ds), in classical music recording studios. At least I would have a recording-studio-level system, to which classical recordings are tuned. However, the local Classe distributor charges $20,00o for amps that cost $12,000 in the U.S., whereas my dealer above can obtain the $18,000 Spectrals at the same price as in the U.S., so I thought it would be a better idea to shoot for the Spectrals.
Now I'm trying to find out all I can about the Spectrals, how they could match the EMM Labs Switchman 3 (as Spectral do not make multichannel equipment, so that I cannot have an entire Spectral system), and whether I can use my current, great sounding $3,500 Purist Audio Design Venustas parallel bi-wired speaker cables, instead of selling them at (great) loss and buying MIT cables instead, who knows at what price.
In short, I wish things were as simple as you pictured them... :-)
Best regards,
Amir
Just in case I needed to clarify, my post was not in reference to Viagara, but rather to Amir's post in which he quoted MIT as saying:
""Spectral amplifiers are not warranted for use with speaker cables other than MIT."
That is patently illegal without either:
1) Providing the cables for free, or
2) The permission of the United States Government.
Somehow, I doubt Spectral is doing the first or has the second.
Hi, BillK!
I would bet nobody misunderstood what you referred to :-)
My quotation was from Spectral's site, not from MIT.
What you write about the doubtful legality of Spectral's policy makes perfect sense to me...
I wonder when the quoted law came into effect (it might be newer than Spectral's policy) and whether Spectral insists upon its policy (of voiding the warranty) nowadays, even in view of that law.
Regards,
Amir
Dear Amir, First I don't want to come accross as the expert with Spectral I have not been a dealer for a long time. I do suggest that you write to the company and ask them about what you want to do. I think you are going to be told that your system design is not what they reccomend. Those amps as I remember require a spectral preamp tp drive them because of the input impedance which is not the same as Classe, or Krell etc. Audiophiles seem to ask the same question in many ways so they get the answer they want rather than what is correct. I would check on what I am saying since maybe they changed something although I doubt it.
Spectral is a different bird it is made to be used amp, preamp and cables together. I know of no such thing as universal gear from them and to my best knowledge this is NOT their philosophy and will never be.
My friend and I were discusssing on the golf course all the harm these forums, internet, magazines, dealers do with not enough information. Many people say this is bad or that is bad when many times, not all, the products just do not work together because of the science and therfore will not sound good.
For your own information if you are going to buy those amps to make sure you get what you need and what you pay for contact the company and tell them exactly what you want to do. I believe you will be illuminated.

I'd be only too glad to write to Spectral directly -- I failed to find any "Contact Us" in their site.
If I had a way to contact them, I'd have tried it long before attempting any forum.
Do you know of any way to contact Spectral directly?
Best regards,
Amir
Spectral makes a version of their amplifiers that has restricted bandwidth and thus doesn't require the use of their or MIT cables. These amplifiers are intended for use in recording studios.
I was not aware of the law that prohibits a manufacturer from requiring that another product be used with the first product.
Incidentally, I've mixed and matched Spectral's power amplifiers with other preamplifiers, and used the Spectral preamplifier to drive other power amplifiers. I've also used the Spectral SDR-4000 Pro at the front end of a variety of preamplifiers and power amplifiers. Although there are no ill-effects from this system matching, you need to hear the entire Spectral chain as intended to fully appreciate the performance of each component.
Dear Mr. Harley,
Thank you for yopur response!
I suddenly realized I've lost my focus on the main issue and got carried away with side issues such as the MIT cables.
The main issue is what to do, given that:
* I fully understand that the DMA-360s are in a class of their own
* I fully understand that for obtaining the best from the DMA-360s, one has to use a complete Spectral system
* I consistently prefer my (mostly classical) music in multichannel over stereo-only (with very few exceptions of tradeoffs),
but Spectral do not make multichannel equipment, so that I cannot have a complete Spectral system.
It therefore seems conceivable that the DMA-360s are so good that even when not in their optimal environment, they still outperform all competition.
The main options I currently see are:
#1. Remain with the Hurricanes (which just went to the technician again :-)
#2. Buy a DMA-360 for my existing system (with EMM Labs Switchman 3 multichannel preamp and B&W 800Ds),
with or without MIT cables (whose usage seems to be controversial as regards both sound and warranty)
#3. Buy Universal Spectral amp(s) for my existing system
#4. Wait for EMM Labs to issue power amp(s) someday, so that I'll have a complete EMM Labs system
#5. Shoot for other power amps, such as Nelson Pass
What would you recommend?
Thanks!!!
Amir
Hi Amir,
Can I suggest of these...
#1. Remain with the Hurricanes (which just went to the technician again :-)
#2. Buy a DMA-360 for my existing system (with EMM Labs Switchman 3 multichannel preamp and B&W 800Ds),
with or without MIT cables (whose usage seems to be controversial as regards both sound and warranty)
#3. Buy Universal Spectral amp(s) for my existing system
#4. Wait for EMM Labs to issue power amp(s) someday, so that I'll have a complete EMM Labs system
#5. Shoot for other power amps, such as Nelson Pass
...you go with #5. Or in fact, any amp you can actually audition within the context of your own system.
I'm a dealer (though not for Spectral) and can attest to some of the comments made above in regard to system matching and electrical loading. But the systems we sell we sell to people who have heard the results first-hand, rather than having talked about them - on an internet forum no less... I admit that there are components which are currently re-defining the 'state-of-the-art' apropos music reproduction in the home, and that my curiosity about these products is never ending. But, as I tell our clients, we sell a result. Not an idea. Not measurements. Nor an ideology. We sell a result that comes from the client experiencing the system together at one time, in one place, and at the end of the day it is their responsibility to decide if the result is commensurate with their own preferences and prejudices and their resources. Our responsibility is to make that process as transparent as possible, and once the sale is done, make sure the system performs consistently in relation to it's performance envelope and does so reliably. If not, then we pester the distributor of that product mercilessly until satisfaction is achieved.
In my opinion, if you cannot know from direct experience that you will get a result that is commensurate with your own listening preferences and financial resources, in the context of your own system, and have that product backed up by dealer and distributor support in your own country, then frankly, keep your wallet in your back pocket until you can.
Cheers.
