Works great with my Martin Logan SL-3's driving the woofer with a PS Audio GCC-100 & Cary SLAM-100 mono blocks driving the 'stat panels. The GCC-100 'gain cell' volume control drives both the power amp section of the GCC-100 and the Cary's via the output jacks on the GCC-100. I don't need to balance anything, the GCC-100 is 100 SS watts per & the Cary's in triode are 95 tube watts each - seems to be a great marriage for the Martin Logans - more than enough power & the tubes on the top really flesh out the panels, which can be a tad lean with SS amps.
