I just want to know if Ken is refering to the results from the PS600, as being dynamically constricted and sluggish, while the amp(s) are plugged into it or not???. I have a PS300 that has absolutely non of this! I can, however, immagin running into concerns with any of these powerplant (performance wise) if you are trying to drive an amp with them! I think your probably better off just plugging sources and what not into em....
