High Quality Integrated to power Mani-2

Does it have to be new, because I think the Musical Fidelity Tri-Vista wouuld be a nice addition to that list, and it goes for slightly over 3500 on agon. I think it would be a better option than the A5 (plus it has an adequate phono stage).

Not sure if 1 ohm is accurate for the mani-2's but I'd take the 400xi off there. It's a really nice amp but it's not equippped to drive high power (mani-2 = 85db) into low impedences. See the measurments from Stereophile.

I've extensively auditioned a number of integrated amps, including those that you've mentioned, as well as the BAT and McIntosh for my Totem Forests. Although somewhat different specs from the Mani-2's the Forests also like power, but the don't have the low impedence issues. I ended up with the DK Design MkII, and have not regretted the decision. It also has a phono stage. You can pick up a MkII for a good price used, or go to the MkIII, which, I hear, has some minor improvements over the MkII (a change in some of the caps). The change in ownership also seems to be a positive for DK, but I had excellent dealings with Daniel in the past wrt minor warrenty issues. Worthwhile to audition in any case.

Look at GamuT.
My model 1's loved it.
