I'll be building a multi-channel amp in the coming weeks, and this question has been on my mind...linear vs switching. @twk123, which one did you go with, and would you go that route again? I already put together a TPA3255 with a linear supply and it sounds phenominal, but if I can go lighter on the PS, that wouldn't be bad.
I'll be putting together a 5 channel receiver with TPA3255s or 51s, with individual level adjustments per channel, and a master volume control. After reading all of the recommendations, I'm leaning towards a switching PS, just wanted to see how happy you were with the results.
