Had this post up a week or so ago, but the board seems to have lost all posts from then (server crash?). Anyway, I've ordered our new HT speakers: RBH 661LSE (Mains and Center) RBH 66SE (Surrounds) RBH 1010SEP (powered sub) I've been assured that my current receiver won't drive these speakers adequately, so I'm looking into using an amp with a Yamaha 2400 receiver as the pre/pro. Someone on this board previously gave me some nice suggestions on amps, and I've been looking into them as follows: Rotel RMB-1095 5x200W, 2x1.2kVA transformers, 8x15kuf caps (120kuf total). Sherbourn 5/5210 5 "monoblocks" x200W, each channel with a 400VA transformer & 2x10kuf caps (20kuf total per channel). Parasound HCA-2205AT 5x220W, 2kVA transformer, 150kuf capacitance total. Separately, I've been told that an amp should have a minimum 85db S/N ratio at 1W, and all these handle that. My questions then become, how best to differentiate these amps? For HT, supposedly the monoblock architecture of the Sherbourn is not as good as the common power source of the other two - true? In any case, please let me know any experience or knowledge that you might have in regards to these amps, or if I should look into a different one altogether. As mentioned previously, we are new to high-end but we'd like to get an HT system that we can have for 20+ years if possible. Thanks in advance!
