I can't comment on any of the recent offerings from CJ as I haven't listened in a familiar system but I HAVE been listening for the past year to a PV9a extensively upgraded including bypass caps, resistors, diodes and wire among other things by Bill Thalmann in Virginia. All of this made a quite excellent performer into quite possibly the most engaging preamplifier I have personally owned. Only downside, too much line stage gain and limited in the use of medium to low output MC phono cartridges and no remote which I don't view as a necessity although a nice convenience.
