I've been using a Bob Backert heavily modified PV12L for years now and it is awesome. Even before the mods. that CJ smooooooothness was there. I always attribute much of their gears' sonic success at the attention to the power supplies in their designs.
Almost bought a CJ SS amp years ago, but ironically enough went the McCormack route. As fate would have it, McCormack is now a CJ line!
