I'm taking my Rotel Surround gear downstairs to make a nice little HT. Never did care for the Rotel gear for stereo anyway. I'm looking for entry level Hi-end ( Krell s-300i To somewhere under $10000.00) I have not heard either of these units, but have had the pleasure of being interduced to Nad Master series M3-M5 set up at a local hifi shop. My question is How can I compare all of the different units without hauling my B&W 683 floorstanders to each and every dealer. Do I just take cd's that I'm familiar with and just look for the best soundstanging, speaker disappearence, ability to render music at all levels, or just when they turn it up. My B&Ws seem to come alive with more power added to them. I will admit the Nad M3 connected with balanced cables to the M5 sacd/cd player made it as if James Taylor was sitting in a chair about 7 feet in front of me. I also have a problem of soundstaging, I hate when you can tell music is coming from the speaker and you know it. I want transparity.
