Peachtree Audio is a division of Signal Path International—a firm headed by audio veterans David Solomon and Jim Spainhour. More so than many people in our industry, David and Jim have demonstrated a gift for developing products that combine the best elements of old-school, two-channel audiophile thinking (where sound quality always, always comes first) plus a new-school, digital/computer audio-savvy mindset. The end result is a series of new-age hybrid (that is, tube/solid-state) integrated amplifiers that incorporate built-in DACs with coax, optical, and USB inputs, and other connectivity features, as well.
First came the Peachtree Decco, a sweet sounding little 50Wpc amp/DAC that sold for $799. The Decco was well received in the marketplace and was a very good performer, though its amplifier section arguably did not have enough “oomph” to handle all types of speakers well. Down deep, however, David and Jim knew they could do even better if they built a more accomplished, upscale “big brother” to the Decco: one that offered a better preamplifier section, a more powerful amplifier, and a better built-in DAC. Now, that hypothetical upscale product has become a reality in the form of the new 80Wpc Peachtree Audio Nova hybrid integrated amplifier with built-in USB-capable DAC ($1199), which we will review here. But before we jump in, let’s step back to get a better “big picture” view of what the Nova is and does.
The Nova, of course, can be used as a traditional high-quality integrated amp, but in principle it is much more than that. The versatile Nova can, for example, also serves as a high-quality preamplifier or headphone amplifier with—at the user’s option—either solid-state or Class A tube circuitry engaged, or as the front-end of a variety of all-digital systems (systems fed by PCs or Macs, Squeezebox or Sonos devices, and the like). But one role you might not anticipate is that the Nova can also function as an ultra high-quality “remote switchable” 24-bit/96kHz standalone DAC—one that sounds so good, according to Peachtree, that it invites comparison with dedicated high-end DACs selling for more than the Nova does. An outlandish claim? Perhaps, but it’s one we’ll enjoy putting to the test.
Consider this amplifier/DAC if: you value sonic refinement, versatility, and value in roughly equal measure. The Nova makes an ideal starting point for those looking to build seriously good yet also sensibly priced high-end audio systems, and it provides a DAC section good enough for use in very high-end systems. The key to the Nova is that it combines multiple functions, each of which is a strong performer in its own right, but which together add up to a stunning value. For about the price of a good integrated amp, the Nova is all that and so much more.
Look further if: you have power-hungry, low-impedance, or otherwise hard-to-drive loudspeakers (e.g., Magnepans). The 80Wpc Nova amp is pretty stout, but not that stout…

Comments
I pretty much agree with everything in the review. For the price this unit is pretty hard to beat and is a great way to get into hi-fi without spending a fortune, and retains enough usefulness to last a long time (as DAC, as headphone amp, as amp for a secondary system). I really liked the headphone section with my AKG K701 and the amp didn't seem to have any trouble driving Synchrony Ones at sane volumes.
One minor complaint I had about the DAC portion, however, is that it can cut off the beginning of audio when used with some sources. I don't know if it has to do with how it acquires a lock or what, but when using it with my Squeezebox or Oppo DVD player (I think it's the DV-971H), the first 1/4 seconds or so of audio is cut off, often causing some music to miss the first beat. When connected to my PC sound card, I didn't experience this issue. Similarly, I didn't have this problem with the analogue inputs.
I emailed David Solomon to see if he could comment on the issue, but haven't heard back. I also posted a bug on the Slimdevices bug tracker to see if there was anything that could be done from their end.
In the end I'm going to be returning my unit because the money could be spent on some other stuff like furniture for my new house, but once I'm in the market for a second system this will be high on the list.
The clipping of the first note can be attributed to the Oppo player (not the DAC): See the comments section here: http://www.hometheaterhifi.com/universal-players/234-a-secrets-dvd-player-review.html
Maybe Oppo has fixed the problem with their latest firmware? -Scott
its not just an oppo problem. i am also having the same problem with a rotel cd player digital co-ax to the dac
Hi All,
Thank you for all of the comments and feedback.
We were able to recreate the problem of the DAC ramping up too late to catch the first note of a song w/a few components and found the cause.
Most of the Novas are unaffected, however, If you are having a problem with the dac ramping up into the first beat, we do have a fix by opening the DAC input parameters. Please give a call to David Richardson @ 704-391-9337 for an RA.
Best wishes,
David Solomon

When will audio reviewers learn to review digital devices properly? A lot of devices tout USB interfaces but the bit rates are never specified nor are the audio reviewers savvy enough to run high bit audio files and proper playback tools. They tend to get stuck wth iTunes and a whole slew of 16/44.1 files somehow downrezzed into FLAC or whatever. God forbid they try to use VLC or Foobar with a nice 24/96 WAV file.
Now then.... what is the sample rate supported by this box over USB? Will it do 24/96 files? Will it require a driver installation? Does it support ASIO drivers?
Also, going forward, 24/192 and like bit rates are beginning to ship. I think the makers of these consumer boxes have been too long stuck on Red Book and are failing to jump ahead. What are the chances that this box will be upgraded to 24/192?
My last comment is on the hole for the add in box. Is there a chance to have an alternate plug in module with something like Firewire?
I would like to run the VA Mozarts off of a Sonos system via the Nova. Thanks.

I'm primarily interested in this and the Benchmark as a headphone amp (other features welcome bonuses.) I'd like to know which you prefer for head-listening and how both compare with similarly priced (or cheaper) heaphone amps.
Thank you Chris, interesting review.
I was following Nova news for some time. Do you know whether Peachtree sells Nova's from their site already?
And can you list what equipment you used for the review?

I've had my Nova for a couple of months now. I believe I was one of the first people to alert David @ Signal Path that the Nova was clipping the opening notes of certain songs (compressed or uncompressed) I played via USB from my iTunes/MacBook Pro laptop setup. As soon as they had confirmed the problem they had a software fix ready to go three days later. They issued a call tag, I sent my unit back at no charge to me, they upgraded the unit's firmware in about 30 minutes and got my unit shipped back to me the same day they received it. In total, I was only without my Nova for 5 business days and it cost me nothing. The customer service I received from both David Solomon and David Richardson at Signal Path was outstanding. It's a terrific company and it's why I owned a Decco and ERA D5 monitors, then upgraded to the Nova and a pair of Usher Be-718's in my home office. Their products sound great and provide incredible bang for the buck.
Regarding the question about the USB input, it's 16/44 only. It's completely plug & play with Mac, no drivers needed. If you want/need to use the USB output from your computer, like I do, yet want to enable true 24/96 playback of files so encoded I suggest purchasing the Bel Canto 24/96 USB Link. It has a USB input and a BNC output with an accompanying short BNC/RCA cable so you can use the coax input on the Nova which does support 24/96 decoding. I just received mine yesterday so I don't have any feedback to provide just yet. However, despite the recent thrashing of USB by Alan Taffel in the latest issue of TAS, I think the jitter reduction employed by the Nova helps it avoid a lot of the shortcomings he illustrated. We'll see how much the Bel Canto 24/96 USB link actually improves the sound through the Nova. As I'm sure you know, he also reviewed this Bel Canto unit in the recent issue of TAS and has some positive things to say about while using it with his specific range of gear.
In terms of how the Nova performs, my comments would merely mirror those in Chris' review. I found the headphone amp section sounded excellent when listening through my AKG 702s, it's not just a feature added on as an afterthought. When you consider this unit's strengths as a killer DAC and headphone amp with a very good integrated amp thrown in and all its flexibility with the digital and analog inputs provided, you cannot touch it with any other combination of components out there for under $5K. It's a deal, it's a steal!
In terms of upgrading, at some point, should my job and the economy allow, I would look at incorporating a different amp (I have my eye on a First Watt F5) and see what that might do in terms of changing/improving this combo's sound but until then, I am extremely happy with this gear and have enthusiastically recommended it to all of my friends as a great entry into the world of true high end audio.

Any thoughts on the Nova driving Paradigm Studio 100s w/ 80 wpc? Perhaps an outboard amps is the way to go? Looking for a setup that supports digital music, sonos without having to shell for an outboard DAC...
Not to deafening levels, or as well as a seperate power amp, but I am doing just that while I wait for my VTL MB185s to arrive. At which point I will put the Nova back in my office and use those and the TL 5.5 pre to drive the studio 100s. They are an efficient speaker.
