I hope break in is true

Sean and all you other smart people: Do break-in discs have to be played loud to work, or will moderate or even low volumes work? What if your system already sounds really good and not bright, but still very detailed--is this break-in disc maneuver still a useful thing to do?

My experience is that this type of disc can benefit components at line level along with those operating at amplifier output / speaker level. As mentioned, i've used this on digital sources without signal making it to the speakers and i've always been able to tell / hear the difference as a component "settles in". Obviously, the more of a "work out" that you can provide for the entire system, including the amplifier / speaker ( without damaging them ), the greater the potential for differences in performance.

I have used this disc many times over on systems that have hundreds / thousands of hours of use on them. A short period on "repeat" is what i would recommend. In my opinion and those that have heard / experienced the differences before and after, the results were always worth the limited amount of time, effort and money involved. Sean

I must echo Sean's warnings about audiophile break-in and (especially!) test CDs. At high volumn they can do damage and I blew out a set of new super tweeters when running such a CD at high volumn. Only then did I read the instructions "do not use high volumn..."

Mdhoover: I agree with Sean and Unclejeff. A disk like this will benefit without the amp on, or with the amp on at any reasonable volume. I would recommend amp on at a normal listening level.

Sean, Unclejeff et al,

OK, so where do I get this CD?
