HOW MANY TIME?  (72h, 2 weeks?)

JLeeMD -- Wed, 06/02/2010 - 19:13

Analysis Plus states 300 hours for their cables.  Audio Research states 600 hours for their solid-state equipment.

Do audio components and cables need to be burned in again if not used for a few years. Also does burning in reduce the life of the product? By burn in I mean long hours of play.

I use a 600watts  incandescent lamp  = 4,7 Amps continuous for 96h in powercords.  Or i plug in my refrigerator.
For speaker cable and interconnect i use DC and AC low current (using XXsecret) for 10 days.
Results....oh my god!

George Cardas has some great answers to the above questions on his company's website:
When I bought my new Cardas Golden Reference speaker cable, the recommendation was for at least 100 hours (4 days) of burn in.  I got the dealer to burn them in for me - they had a burn in machine (built by one of the cable manufacturers - Nordost?).  They waived their normal fee of $75 for the service, although I still might have paid for it to save 100 hours of play on my CD player!

I find that loudspeaker cables take about a week of continuous use to sound their best. Most of the cables I receive have been burned in by the manufacturer. Nonetheless, they still exhibit improvement after they settle in to the system.

I noticed exactly that Robert! There were continual improvements to the speaker cables over the next few weeks of listening in my system (post dealer-burn in). George Cardas talks about the need for his cables to "settle" after they have been moved around - I wonder if he's onto something with this?

Robert Harley -- Wed, 06/23/2010 - 15:01

This "settling-in" phenomenon can be quite profound. I've experienced it perhaps hundreds of times; the system develops a greater sense of ease and liquidity after a few days. You really hear this at shows when listening to the same system on the first day and the last day (with no changes in set-up or gear). I'm sure that if the systems were left there for a week, you'd hear even more change over that week.
I've also found that once the cables are in-place, moving them starts the process over (not entirely, but to some degree).

If a system or component is not used for a long time year or things need to be burned in/ broken in again? for lesser hours may be? what if upgrading a component? and do burn ins again and again/ long hours of use reduce the life of a component.

This is an easy one and really does separate the snake oil peddlars or the deluded from the realists. Cable burn-in is a complete and utter mythical concept that amounts to serious misinformation. Robert Harley, I hate to include you in this category but you are supposed to be a knowledgeable hi-fi expert giving sound advice. just why are you propagating this myth? Is it the same reason why you are willing to interview company reps about the merit of their low jitter technology but ignoring the independant scientific papers that find that Jitter is not audible at the usual levels in basic equipment? It's scientific fraud at best.

Ask any reputable scientist or technologist or anyone who knows anything about materials and basic electronics and they will tell you the same.

Ever wondered why people support the burn-in effect - its a convenient cop-out from the situation that is experienced when the rather uncomfortable finding that your expensive cable is actually not doing anything that a light flex does. The scientific community really is laughing at this claim. Ever wondered why there are no scientific papers on the subject? Ever wondered why no proper studies have been published? Ever wondered why it's not taught in Physics? Ever wonderd why there are no scientific guidelines at all. It's audio anti-science, snake-oil, audio voodoo, food for idiophools - plain and simple.

Luce to answer your question then - don't bother with it. What is actually happening is to do with the 'human factor'. - it's basic human psychology at work. The human subjective listening process is very transitory and volatile. If you have been told that something has changed in your system you will often hear a differrence. If you listen for longer or more intently you will seem to hear differences. The same piece of music will sound more detailed the more you listen to it as your mind is tuning in to the detail. Similar to the cable myth and non-blind equipment review, psychology plays an (often unappreciated) overwhelming part in subjective audio quality.This is the very first thing to learn if you are at all serious about assessing audio components objectively.

I support the 400 -hours rule, for cable burn-in.
