Here are few to consider, Gryphon Diablo, T+A PA3100HV, Accuphase E-5000 and darTZeel CTH-8550 MKII. I would seek an audition from your local dealer to see which one of these offers the best synergy with Sabrina’s.
I know a dealer in Florida who carries ~ Wilson, Gryphon and Dan Agostino, Nagra and he often demo Wilson with Gryphon. As I pointed out, synergy and your personal preferences will be the ultimate determining factor over everything else.
I hate to point out but when you own 87dB efficiency speakers, your choices are limited to high current amps / Integrated’s.
