I have two older RM-40's with spiral tweeters set up for either mono or bi-amping plus a MLS decked out RM-40 ( with less than 100 hours on it) all in oak, plus the late James B's trinaural adaptor all in air conditioned storage. To get better sound than this you have to go to my RM-V60's with dual mid bass units, and there the margin is slight! Shipping will be a bear, but if that is a worry, you don't deserve them.
