Amps to use with Von Schweikert VR4jr's

I took my SST Son of Ampzilla (100wpc x 2) to a friends house and we spent some time with the SoA on the VR4jr's.

For a high dispersion speaker, I thought it sounded truly remarkable from top to bottom in an untreated living room.

Great highs, rich midrange, and Solid, Deep bass.

I am running a BAT VK75SE. It can deliver some real magic with the VR4 JR. Previously, I was using a hybrid amp, an Anthem Amp 2SE (tube 1st stage and solid state power). The Anthem was also capable of delivering "magic" with rhythm and texture. The BAT was a step up in coherence and midrange, but didn't give up much in the way of bass slam.

These speaker seem to be able to use whatever quality you can deliver from the electronics.

I love my VR4jr!! I have a Sim Audio W5 driving mine and the sound is remarkable. Liquid smooth, details galore with imcredible grip on base. When I added a Supratek tube preamp, it took it to a whole different level, soundstage went further beyond speakers then I could have ever imagined, left to right, front to back... Now I know what people are talking about when they say 3D and holographic sound. My dealer runs them with the new Classe stuff... also truly amazing.

These things will certainly tell you what quality of electronics you are driving them with. They are very neutral speakers and if you have some coloured electronics driving them be prepared to hear what those auxilleries really sound like.

Good listening.

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
