I have Spectron mono's with my VR4-jr euro-mods. I started with a single stereo amp with bybees and vcaps. I was real pleased so I added the other..probably overkill for me but I couldn't resist. The Spectron replaced a Bryston amp..I couldn't believe the difference. I think Spectron used to be Albert's go to s/s amp...now I think Channel Islands took that spot. Even knowing that I don't think you can better the Spectron. Very smooth when coupled with tubes upfront.
