Lately I've been looking for some information and specs for those beautiful Japanese poweramps graced with VU meters from the eighties. Just for the sake of it you have to choose your favorite: Alphabettically arranged: 1. Accuphase M100; 2. Denon POA-8000; 3. Onkyo M510; 4. Rotel B-5000; 5. Sansui BA-5000; 6. Yamaha 101M/PC5002 The first two contenders are of course monoblock designs but the others (for except the Sansui) are true dualmono designs. I've had only the Denon POA-8000's in the eighties but it could not properly drive my Infinity Quantum 2's. Which one is your favorite and why? Or another (missed) contender maybe?
