When I asked about Peachtree Nova it didn't get a lot of love being a Class D amp. Everyone kept saying something along the line of I never heard any difference but would not own Class D amp for hi-fi.
I did like many of the other features Peachtree puts in their integrated amps. Their "philosophy" is very close to mine; 2.1, USB DAC (PC and Mac compatible), good headphone amp built in, analogue inputs for phono, etc. But there's also some bollocks, like a tube for natural sound, which I don't like.
Many subwoofer designs (even very expensive ones) sport a Class D amp as the shortcomings should not be audible at lower frequencies. But it appears you might hear them when playing high and loud.
I'm sorry you asked only after you bought it. At first you asked about Naim, which although overpriced measures pretty good from what I read at stereophile.
I plan to have both setups in the living room for A/b comparisons of Amp speaker combos. Once I choose the winning combo, the second set will go the bedroom for more mellow duties.
I am a fake audiophile, and a lazy amateur, in that I am more focused on the music and less on the gear. I listen to everything and the kitchen sink.
I am beginning to try and get the basics right in terms of placement, acoustic treatment (sans acoustic panels and the like -just natural stuff - carpets, curtains, canvas paintings and the like which I get some room to manœuvre, with the final say so from the wife.
But my ears do tell me that I want more lower notes, first with the Naim and KEF LS50s and now with the Peachtree 220 SE and Harbeth M30.1s. Jazz sounds wonderful, and I have no complaints in the main. But my ears tell me they want more of the lower notes, and I do want a subwoofer for rock and blues.
I bought the Naim Nait used(2 months old), at a very steep discount, and the KEFs brand new. The second set is all second hand at great prices relative to retail, so am not concerned about having overpaid!
