I received a Powerstage 700 Friday evening I had ordered, I took my Sweetwater sales rep's advice and stayed with the Eminence EM12 and stopped pursuing frfr solutions that I was struggling with. Switching from the TC Electronic Bam200 to the Powerstage 700 made a huge difference, not only in the sound of my rig but the touch responsiveness when playing. I wasn't expecting that much of a change, it was a purchase to allow me to move towards a stereo setup, but I'll take it nonetheless.
I did load one of my Kones in the 112 cabinet and it sounded better than it had before but still had a fizz that seems to be present over the whole eq spectrum of the speaker. But that was my experience with all the other frfr speakers I tried, so it's just me and not the frfr speakers.
To be honest I was getting close to selling the profiler and going back to a tube amp but today I'm very happy I kept trying different options. I've been auditioning profiles and with the eq on the Powerstage and monitor output dialed in each one is a very good representation of the amp profiled, different in tone and characteristics.
I've never had an amp sound this good by itself, let alone with the benefit of of being a chameleon of multiple great sounding amps in one unit with more stomp boxes and effects available than I'll ever use. I imagine that I represent a very, very small category of users, I no longer do multitrack recording nor do I intend on playing live where I need to be mic'd up, so I'm not really using the Kemper as intended but as a combo amp. But as of this weekend it has become the greatest combo amp I've ever encountered and has surpassed all my expectations, it just took some work on my part to find the component combination that best suited me, and that combination is killer!
