Hey @88man, I own the JC2 BP and JC5, and have absolutely no complain on the sound. Very neutral and musical, and tiny touch of warmth. It's dead quiet. Make sure you use quality cable between the 2. I've been using Kimber Kable Hero XLR, and had recently upgraded to Kimber Kable Select KS-1116, and wow, what a difference did it make. Especially with better and tighter bass. There has been a $500 price drop on the JC2 for awhile, and it's probably going to be here to stay.
Having said that, I actually just ordered the Cary SLP-05. I've always been very curious about tube preamps, and have read so many positive comments here. I feel that I've got to try it out for myself even though I like my current setup. Now I can't wait to listen to it.
Anyway, good luck with your search. Feel free to ping me if you have questions on the JC2.
