I had the 600i v1 and loved it. After getting new speakers I upgraded to a Pass X250.8 and SimAudio 740P combo and it was a big step up from the 600i to my ears. I tried various preamps with the Pass amp and it wasn't until I tried the 740P that I felt the combo took a big jump up over the 600i. Assuming the 860a (and now v2) is equal or better than the Pass than I would imagine the 860a v2 + 740P would be a killer combo if you like the SimAudio sound signature (as I do).
The 700i V2 will be on my integrated list if I ever consolidate back to a higher end integrated...
