One of my gripes with displays is their lack of having been properly broken in. I think that is especially true in a "show" situation, like when a manufacturer wants to show off a new item, for example, components have nowhere near the amount of time on them that they truly need to sound their best. I'm using a s/s amp right now in my system, a Cary 200.2, which was sold to me as the demo from last years Rocky Mountain show, and it needed a whole lot of hours in my system before it sounded like it does now (PS: I'm happy with it ...for the moment, anyway) and the rest of my system, Pre amp, Tuner, and CD Player, are all Tube. Likewise, from another source, I purchased some interconnects that were also demos from there and they too needed additional hours on them to sound their best.
