What I can't understand about break-in is why speakers, CD players and other components -- even cables -- can sound great the day you take them out of the box and THEN start sounding like hell for what seem like interminable amounts of time. The worst, for me, were the Gallo Reference 3s, which became hard, brittle, airless and downright painful after about 6 hours, only coming back to life 150 hours later. I'm going through the same thing, if not to the same degree, with a new Raysonic CD 128 CD player. Sounded terrific Wednesday (this is Friday) and has been getting worse every day since. Dave
