Aerial 10T Mk2 - Suitable Amplifier?


Audiophile newbie here. I found a mint pair of Aerial Acoustic 10T (Mk2) speakers at an estate sale. They came with Kimber 8-strand (per polarity) cables (4 cables for bi-wiring) and a Rotel RB-971 (70 watts/channel) solid-state amp. Sound sources are connected via the preamp stage of a Denon DRA297 (no speaker cables connected to the Denon). I’m delighted with the speakers, which eclipse the Vandersteen Model 1 pair that are now my TV speakers. Audiophile friends have made amp suggestions including bi-amping. I’m hoping for suggestions from Audiogon members regarding amp (or preamp and amp) selections that would bring out the best in the Aerials.

Parasound A21 minimum. If you can find used a McIntosh MC-352 would be perfect.
When those speakers were current, Aerial recommend high power Theta or Classe mono blocks   A friend had a pair, we liked them with Pass X250, did not like them with Parasound A21
McCormack DNA500, or DNA225 - preferably upgraded by SMc Audio.
Cary 500MB monos but not the 500.1s
Ncore would work too, but the higher up the chain the better with the best value being the NC500 monos from Acoustic Imagery for $2K
