I was struggling on what Dan001 asking as well. I was told no matter how good (claimed to be) and expensive a pre/pro is, it has no comparison to a 2-channel preamp provide both are in similar price or somewhat more $ in a pre/pro, due to manufacturing costs when dedicated to 2 channel instead of 5-7 channels. Especially when both has Balanced circuit which are costly. Correct me if I am wrong. For me, I would rather instead of spending the $ for upgrading to a Casablanca III for both music and HT, to a decent 2 channel preamp.
p.s. to be exact, I am saying like a Casablanca III/lexicon(extreme DAC) vs ARC ref.3 or Cary SLP-05....
