Nice to see an excellent, well written review of the Audio Research D-70 mk2 amplifier. Having owned one of these amplifiers, I can agree with most of the comments of the review. For the current used market price, this unit along with the ARC D-115 mk2 are amazing amplifiers for the money. If your speakers can be driven with 65 watts per "tube ...

Audio Research D-70 MkII – Paul Cervantes

The RM-200 was my idea. I waxed lyrical to Roger about my Audio Research D-70 MkII and what I regarded (and still regard) as the magic of two 6550s in a hard-driven circuit. Roger listened to me, and he listened to the D-70 MkII. Still, the ARC offended his sensibilities.

The mids are pure tube- elegant, rich and liquid with just a hint of that "romantic sound" that I hear some reviewers talk about old tube gear having. The top end is clean, with just a hint of fuzz (this was reduced with new output tubes, and re biasing, but is a symptom of the design). Weakness: Heat and weight.
