Any love for the Belles Aria or other recent Belles amplifier?


I recently heard a Belles 150a Hotrod with Triangle Zerius speakers and a transformer volume control.  The sound is one of the most compelling pairings I have heard.  I am considering purchasing a used 350a or a new Aria or 150a ref. v2.

Has anyone spent time with one, two or all three of these amplifiers?  I'd like to spend as little as possible but still have an outstanding match with the easy-to-drive Zerius.  I like the idea of an integrated if it sounds as good as the bigger amps just with less output power.

Your thoughts would be greatly appreciated!

On a somewhat related note, and sorry to hijack, but was anyone ever able to locate a schematic for a Belles Model Two.   These older units are not supported and i have buzz on mine....thanks
since this thread first appeared I have acquired an Aria Integrated, and based on mine a friend purchased a pair of Aria mono blocks to power much more expensive speakers, and the Arias are simply outstanding...
I was lucky to get my hands on the Belles SA30 class A power amp, what a fantastic sound, very organic and musical. Very happy with the purchase.
