I'm glad Piezo brought up tubes. I bought a pair of B&W Silver Signatures ($8000.00) to use in my main system when I moved it into the basement because they were stand mounted monitors. They didn't have the bass of the Dunlavy's of course, so I tried to insert the Dunlavy's back in, but I couldn't keep them there. The B&W's were so sweet in the midrange that it sounded like the singer was in the room with me. As good as the Dunlavy's sounded, they didn't do that. I used the Krell KSA-50S with both, so I can't blame it all on the 50 watt Krell. But tubes are sweet through the mids, and with enough power in reserve, it may very well the better way to go. Besides ARC and VTL, try giving the Conrad-Johnson Premier 140 a listen.
