I just got my Blues 7B, and it is absolutely amazing. By far the best preamp I have owned. Detail is all there, I heard things in my music that I didn't know were even there. Soundstage is also excellent. It was pretty much a "wow" this thing sounds awesome! The craftsmanship is world class also, and it looks so beautiful. Jim is also great to deal with, a real nice guy and he will go all out to make sure you are satisfied. My preamp did sound a little dark on the treble at first, but after a few hours of burning the tubes in that was gone and I found that I couldn't shut the darn thing off.
