Why does it take so many hours to brea in arc preamps and amps?


I recently purchased a like new ARC 5 SE pre amp.  The unit had less than 200 hours on it.  Everything I have read states that ARC preamps take up to 600 hours to fully break in.  Why is this so and what improvements can I expect to hear as the unit accrues hours?
ewah
So now Charles Hansen is unqualified or just plain lying! You and Bo1972 are the Masters of the Audio Universe. Nobody’s buying it in either case.

I put the SR Black mains fuse in my REL subs about a week ago and had to cut the output levels back at a good bit.  "Previous to the fuses, I could not enjoy low listening levels, the sound was just not rich and dynamic."
You and geoffkait need to get together and write a book on hifi voodoo.

This is just getting stupid.

" To all those that say the manufacture has specified a certain "break-in" period, please link the rest of us to those manufacturers links, instead of it being just personal opinion.

Cheers George "

If you read the info I have you, it was a fairly broad selection of break in requirements. Some list hours, some months, different types of equipment, no break in..... What more do you want? You're making an argument just for the sake of making an argument. Lets continue.

" This test is for weak/faulty components under heat stress, not to "burn in" for better sound."

I know. Do you know how I know? Because that's exactly what they say in the quote.

" "MAY" this is a get out of jail card. Otherwise they would have used the word "WILL" It also infers "Expectation Bias"

The get out of jail card and expectation bias. Now you really got me backed into a corner. How do you explain this?

" Burn-In/Break-In Time This unit has a break in period of about 1 week during which continuous improvement in sound quality will be observed. It is recommended that music be played continuously through the unit during this time to expedite the break in period. "

That's also out of a Theta manual, but for a different amp. Now what? You can't say I tried to trick you (although I don't think that would be too difficult), because I gave you fair warning. Here it is again.

" There's 3 examples. If you want more just read an owners manual. Also, when you read through the Theta example, the break in requirements are different for Class D amp than traditional AB. "

Now its my turn.

" I trust some things Charlie Hansen say's, but sorry not this one Charlie. If this is so with this Ayre CDP, then it (break-in) needs to be done at the factory, after which all adjustments re-done before it's sent the customer. "

What adjustments are you specifically referring to? I have that CD player. There are no adjustments to be made after break in. Not only on that CD player, but every CD player ever made. A straight answer this time. No BS.

" But in electronics just a few of hours see new electrolytic caps that have sat on the shelf too long and such being "formed" if you know what that means to their best, if not they are leaky and need to be replaced. "

OK, so now you are making statements on break in. Show us where you're getting that info from, and why is that statement correct while the vast majority of the audio industry is wrong? I hate to be mean, but look at it from out viewpoint. You have no problem criticizing designers like C Hanson and his peers, but they're the ones making state of the art high end electronics, year after year, and they're following increases. All you do is talk. See the difference?

Does that mean these designers can do no wrong and are faultless? Of course not. But you've shown nothing to support your case other than a will to win the argument regardless of what's actually true. What makes it even more sad, is that I've read many of your posts in other threads, and more often than not, I would agree with you on whatever topics were being discussed. Now when I read your posts, the first thing that will come to mind is, "read it a few times and see what his angle is."



OK, so now you are making statements on break in. Show us where you're getting that info from
Just Google "forming electrolytic capacitors" and be enlightened just a little.

Better Geoff than a pompous flat-earther like yourself.

Get over yourself, everyone else already has.
