Audio Research D200 & Audio Research Classic 60

Familiar with both and owned a 100.2 which I sold a few years back and should have kept. If you offered me any of the three I’d take the 100.2 and I bet between the three will cost you less as well. Between the two though... I’d probably take the 60. 

To me AR were best at tubes, their solid state never really took hold. And the best tube I’ve heard from AR was the D115, and this Classic-60 from it’s looks, could be in a similar design topology as the D115.
