is Accuphase E-406 + B&W Matrix 801 S2


Hi Everyone,
is Accuphase E-406 an A class IA or A/B Class? I will combine it with B&W Matrix 801 S2 Speakers for my recording studio as my Big Monitors.
I have Genelec 8040 as Near Field Monitors, Vintage Monster Cable Pro (1990) and Vandenhull Silver Plated Cables
