I've had my 502 P power amp for over four years now. Completely trouble free powering my Magneplanar 1.7's. I also have a very high power SS Conrad Johnson amp available but I find I much prefer the Jolida (with KT 150 power tubes). A nice solid 3D presentation I find myself listening for hours on end absolutely no fatigue factor.
The Jolida folks were very accessible and answered questions promptly. I ended up getting the power amp version with improved components but it was only a few bucks more than the regular one. For the money hard to beat. I did listen to a Rogue Cronus but I found it oddly to have a sort of SS sound. The Jolida has the a more "classical" tube sound that I find I enjoy more.
