While the Plinius is a good amp, it really is not in the same league IMO.
@daveyf That’s your opinion, but assuming you’ve never heard the SA103 it’s just an unfounded opinion and nothing more. Keep in mind the Plinius is a pure Class A design, which I think the Model 8 is not so that’s a big difference. Also, the Model 8 is anywhere from 25-30 years old, so unless it’s been serviced, re-capped, etc. good luck with that.
