Mrtennis, if you're shooting for purity & silkiness, consider the Reference Audio Mods/Audio Consulting Silver Rock step-up transformer output stage, but installed without the optional op amp buffer section. The SS buffer section adds pace, dynamics, and bass control, but could be omitted if you're more interested in smoothness & refinement. The buffer section could be added later on (preferably with battery power)if you sense any lack of dynamics.

Mrtennis, To each his own, but what you are looking for is exactly what the silver transformers sound like without the active buffer stage.

Hooper, Just curious about what modded players & modders you're talking about, and what were the internal changes made. Did you hear them in a familiar system? IME there are some mods-- particularly improvements to power supplies-- that make decisive improvements in every way. Other changes may be more subjective.
