I have had and listened to many amps and have been in this stupid game many years. I have settled on class d because it sounds so Damn good for the money but also for the convenience. Yes a krell fpb300 sounds better than my sti500 but not that much better, and costs way more up front, way more to run and will probably need repair sooner. The only real area that is better is some image depth and 3d, but its not much. I don't think there is better value than good class d. Plus I have never even listen to good class d, driven by a really good tube amp. That may be the real end game!
Have fun playing the game! I do.
