New Amps for my Avalon Ascent II


I am looking to retire my Roland Model 1's which have been driving these venerable speakers for 16 years. Any suggestions would be greatly appreciated.

My source is an AMR CD 77 with a Music First Audio TVC as the preamp. The room is approximately 30 by 40 feet and our musical taste is predominantly classical and jazz

First time I heard the Ascents was back in the early 90's at Chicago CES. They were in a very large deep room, driven by an all Gryphon system. Music was analog front-end playing a jazz trio. It was mesmerising. The soundstage depth, image density, and tonal accuracy left me in want of these speakers.
I heard Ascent MK2's many times with Rowland Mono 9's, Gryphon Monos, Basis / Wadia front ends, Cardas Hexlink / Purist Dominus cabling throughout, no other system (except Apogee 1-ohm Scintillas) could ever touch it to this day.
You are spot on. That is why the Ascents are the "Archimedean point" of my system. The rest I am gradually enhancing.
