There is sure to be a break-in period required for a digital source before it sounds its best. I think it would be difficult to provide a number for all digital products, but certainly 1 or 2 hundred hours is not an unreasonable amount of time. I am currently breaking in a Sony C-333ES SACD changer, and have had it running for about 8 hours a day for the last 3 weeks. There is no question that the unit is becoming smoother, and now starting to become richer sounding, too (Yes!). Also, the soundstage is projecting further out from the plane of the speakers, why this should be so I have no idea but there are no complaints from me about getting a bigger 3D "bubble" of sound out into the room. (The Sony is a great piece, by the way, and a good way to get most of the SACD magic without dropping a ton of dough.) Play that new deck a LOT and give it time, it's only going to get better. Happy listening everyone!
