Acurus A200 vs Adcom 5800

I have not heard the Adcom 5800. I own an Acurus A250 (which is basically the same as the A200), powering Totem Model 1 biwires via an Audio Research hybrid preamp. This combination gives a wonderfully musical sound, with great accuracy. Many non-audiophiles and professional musicians have wondered (from around the corner) if the music was live. I use a Rega Planet and Planar 3 as sources, along with an NAD tuner, an HK CD changer with HDCD, and Yamaha KX-500 and cheap JVC double cassette decks. I also use a genesis servo 10 subwooofer with 300 watt amp (the monitors run full range). I have stopped the continual upgrade process for the forseable future. So, in response to the Acurus bashing, my ears tell me otherwise. I suggest you audition the amps at home and trust your ears. Rather than constant A/B switching, try long listening periods (including background listening) and be on the lookout for ear fatigue (I have found that many initially impressive sounds reveal themselves to be harsh, over-etched, whatever your preferred term is, over time).
