Pure Class-A Amp under $2000 (USED)

Hello everyone,

There are so many brands out there that I couldn't catch up with, so I opened a thread about Class-A Amp for discussion. My budget is around $2000 for a Stereo Amplifier (No need for Pre), could you guys help me to suggest me some?

- DAC: Exogal Comet

- Pre/Amp: Yamaha Intergrated A-9 (My current, but want to update)

- Speaker: Sonus Faber Venere 2.0

- Cable: Acrolink (Power, Interconnect, Speaker)

=> I think the wattage range between 30-60WPC for Class-A is powerful and popular. The production date of amplifier should not too old, I think after 199x is nice.
