Wilsynet: I am surprised! Maybe I was naive thinking that a $50 2-channel amp would be noticeably inferior to a $2000 amp.
I think if I asked the group: which will sound better:
1) Sonic Impact + headphone DAC = $150
2) Rotel DSP + Rotel amp = $3000
They would say (2). Again, maybe I am wrong. We're comparing a $150 d-class amp with separate DAC/preamp to a $3000 d-class amp with separate (more expensive) DAC/preamp.
I think you are right though that a using just 2 out of a 7 channel amp, even if they are discrete, is not optimal, although now I am very very curious to compare it to a 2 channel ICE design. I would love to understand why running 2 channels out of a 7 channel amp (discrete) is different from running a 2 channel amp. If they are discrete it should be the same, right?
