I have an audiobuddy with the Marsh 400 amp (200w) driving Martin Logans and he LOVES it. He says the Marsh amps are absolute giant killers, with quality parts, superbly built and unfailingly musical. He is not easy to impress so I would audition them if you have the opportunity. Marsh is also coming out with 400w monoblocks in 2001, price-point around $3000. E-mail me if you would like my friend's addy.
