I just saw this thread and wanted to add my experience.
We have a Meridian 800 & 861 front end, MIT Oracle cables and Wilson Sasha speakers. I believe I spoke with Madfloyd when I was considering a new pair of amplifiers. Madfloyd was kind enough to explain his experiences with his 100.5's, that he was a bass player and that he absolutely loved the Lamm 1.2 amp's.
So - off to Innovative (in NYC) I went to listen to the Lamm amplifiers. They certainly are great amplifiers, and after EXTENSIVE direct comparitive listening - I found them to have strong bass. Closest were the Spectral amplifiers, which were a little more dry / lean and yes fast. The Lamms had more warmth and had slightly more bass emphasis.
I'm being VERY critical and could live with either - so please don't respond back and be upset with my statements. I'm merely sharing what I listened to and heard.
So, what did I get? Just to be safe and not have to worry about bass, our Sasha's are now run by a pair of Pass XA-200.5's and they sound more natural then anything I've heard to date. But - to be fair, the MIT MA-X2 balanced interconnects and MA-X SHD speaker cables have a lot to do with this also (with a combine retail of more then the Pass amplifiers!).
Kindest regards, Thomas.
