re-burn in? is there such a thing.

You know I think it does. I recently had to sale two of my CDPs (NAD C542 and Jolida JD100), and go back to an older (90s era) Onkyo changer that I hadn't used for about three years. Everything else in the system stayed the same. At first, the changer sound was somewhat thin, not a lot of body at all, and the soundstaging depth was almost non-existent. Recently I noticed that soundstaging depth and imaging had greatly improved, and that the overall sound had develped some decent body to it.

Well, Levy

You might want to do an extended run with some of your favorite CDs just to see. Over a two or three hour period, yours ears will tell you what you need to know. Bottom line, does your music sound right and if it does, then that's all that really counts.

My changer is run through a integrated tube amp, and I can definely tell over an extended period of time, that things ccertainly start sounding better. Now is it just the tubes or the changer, or some 'synergy" between the two, I really couldn't tell you. I just know the "toe tapping" factor goes up.

One thing I would suggest concerning your CD player is that you leave the Power ON. If you don't want to do that, at least turn the power on about an hour or so before you actualy start playing/listen to your CDs. Truth be told, components DO SOUND BETTER when they are fully warmed up.

Whoa, both Markphd and Nsgarch, getting a little deep here, and especially after Levy said something about not "expound audiophile thingies". Guess a couple people around here must have missed that particular comment. Definely there is a difference between "burn in" and "warm up", but I think our friend Levy doesn't want to go down the overly "technical" road. Basically once your compondents are "burned in", then keeping them warm is all you really need for them deliver their "peak performance".

Once again, let your ears and your music be your guide, as they will tell you all you need to know. It ain't all that difficult nor should it be.
