I bought the JJ Tesla tubes you recommended, have not tried them yet as I also picked up some RCA 12AU7A ECC82's. They are great, the sound stage is wall to wall and the preamp took on a whole new dimension of musicality. So good I allowed my wife to play show tunes (Wicked), the layering coming out of my VMPS RM30M's (extremes with TRT caps and OXO) was nothing short of astounding. I have been playing with this stuff a long time and have owned some very expensive equipment, but I do not remember ever enjoying my system this much. The tubes made a huge difference. I was lucky enough to stumble onto the tube depot approx. 10 miles from my house in Orlando, the owner is a very knowledgeable man. He is getting me some instrument grade tubes to try...
I giggle when I see the recommendations for expensive preamps, when I know we have the best kept secret; the mighty Candela!
