I have also heard that many people describe JR gear as being "tube like". I have a JR amp, but I've never had tubes to run the same speakers to compare it with. I do have a tube CDP, but to my ears a modded squeezebox beats the tube CDP. Is the modded SB "tube like"? Interesting question. I now also have a tube amp (Cayin) for my center channel, and my JR runs my R/L speakers. To be honest, I can't tell much difference in pans between the centers and sides. Does that mean the JR is "tube like"? I don't know. The tube amp has seemed to add an amount of warmth to the vocals that the Nuforce Ref. 9 and Bryston 9B did not seem to have, but the difference is much less than what I was expecting. It's quite a subtle difference.
