I had 10t's and demo'd a 336 with them a few years back.
At the time frontend was BAT VK50SE and BAT VKD5SE CD player.
IMHO the 336 was a good match. Lots of detail without being bright. As with most Levinson amps, excellent Bass control.
I liked the 10t's enough to buy the 20t's. I biamp them with a 336 on the woofers and 33H monos up top. Excellent!
As to the new McIntosh Monos, I've heard them on Aerial 9's and I thought the sound was excellent. Lots of air, plenty of oomph! On louder full orchestral passages nothing was lost and no smearing. Sometimes lesser amps do not fare well with full-range classical, this was not the case with the new 501 monos.
Best,
Paul :-)
