@grantgg I second the idea of joining the Orchard Audio Starkrimson Stereo Ultra amp tour, mentioned above by shkong78. It was an ear opener. I immediately ordered the upgraded Ultra Stereo dual power supply model with extra capacitance. Improved imaging, transients, and realism are the results.
I'm used to VTL ST150 and diy Pass Son of Zen class A amps. Always thought amps had to get hot to sound good. Not any more. Give one a try.
Thanks,
