Amps to use with Von Schweikert VR4jr's

I have listened to the VR-4 jr's driven by the Bel Canto evo-2 gen 2 and it sounded outstanding. This was a recommended amplifier by VS. Images are stable and float in space. Very synergistic combination. I would imagine other digital amplifiers do well with the jr's also. The H2O is highly touted and, I am sure a great amplifier but, I have not heard it. It's on my list to hear if I can find someone with one. I believe this amp has a 30-day trial which, given this it is certainly an approach to consider.

some amps i've tried that work well w/ the 4 Jrs...a Pass x-250, SST Son of Ampzilla, Aragon Pallium II monos, and Rowland Model 10

I've not listened with the VR 4 Jr's, but with their big brother the VR 4 HSE, they sound wonderful.

I have an Audia Flight 100 power amp driving my VR4jrs - the Italian class A beauty has full control over the entire frequency range. It just does it all in my ears. I´m from Denmark, and do not know if Audia can be bought in the US

For those in your situation, but perhaps on a smaller budget, like myself. May want to condsider using an integrated 55 watt amp, with KT-88 tubes. The SQ-88 from Quest for Sound. From a dealer on this site. A great musical combination. With your budget in mind there would be some other amps I would like to try just for kicks. I would be more inclined to try any SS amp with a class A output. I've not had a chance to listen to a SS amp yet with my jrs due to lack of having a preamp. But at this point am content with tubes.
