I auditioned the vk200, the clayton m100 monoblocks (till I could try the s40) and the plinius sa100mkIII. I think that stevegolf1 described the BAT deadon. It did have very impressive bass, but the treble felt a little rolled off (hence, it was helpful at softening sibilance). The Plinius still provided good bass (and as I have a sunfire subwoofer, it wasn't as important to me) and offered superior detail, definition and separation in my system.
The S40 is very much the same sound as the M100 monoblocks, just less power. In terms of bass power, I'd say BAT first, then Clayton, then Plinius. But the Clayton had a slight lower-midrange hump that while I found very pleasing, especially with vocals, was not something that I could see myself wanting to keep longterm. The plinius was the most neutral of the amps I tried. I enjoyed it in AB, but give it about 30 minutes in Class A and the music just got deeper and sweeter.
Hope this helps.
