I was on the forums a while ago, got busy with work and not getting back into the community again.
I have been using a Nord NC 500 amp with the new class D buffers, incredible amp. Also a Devialet 140 which is stunning.
I have alternated between a pair of gradient revolutions, with the dipole bass, and some Stirling LS 3/6. Have gotten a lot of good advice from Robert E Greene, thought I do find both amps and DACs have a lot more variance in sound that he generally suggests.
The full suite of Gradient speakers is terrific, I had Helsinki 1.5 and the mids/top end was gorgeous.
