Here’s a couple oldie's:
AMC CVT-3030
Ensemble B50 Tiger
I owned the AMC almost 30 years ago, a nice sounding unit, I always wanted to own the B50 Tiger.
Thinking Hybrid Integrated.
Pathos, ModWright Instruments, Rogue Audio, McIntosh who else am I missing? Have to buy online. No high end dealers where I am at,
