To me the HD650 are darker than neutral. So is the Mad Dog V3.2.
I haven't heard the M&M - but a lot of people called the Arrow (portable) flat (neutral) to slightly bright. I loved the Arrow with the HD600s.
With the HD600 - my Audio-gd NFB-12 is supposed to be a touch on the warmer side of neutral (I call it full bodied - go figure). It's nice with the Senns. A neutral amp like the Arrow is also great with the Senns. I would say that the M&M - even if they are slightly brighter than neutral will still be good with the Senns.
I really can't see it being "painful" unless you are completely treble sensitive. Anything you can give us as a reference to your sensitivity to high frequencies?
I would agree with you on the DT 880's and Grado's being bright.
I cannot speak for the HD600's or the HD 650's signature as I am yet to hear these, however I am forever tempted by HD650's in the trade section.
I have a pair of MadDogs that have just landed in Aus, so should have those in a couple of days and I will update.
I have used my AudioGD 15.32 with my Alessandro MS1's with wooden Cups and my LCD2's with Silver Dragon Cable.
I can safely say that the AudioGD amp/dac tames the highs somewhat. In my opinion, perhaps a little too much on the darker LCD's, but on the Grado's I find it nice as you still get that punch through the mids and a musical sound minus the eye twitches and headaches.
With the LCD's I used a plugin for Foobar and added the slightest bit of trebble. Everything else I found perfect.
In saying that, the AMP/DAC doesn't seem to lose detail as such and the treble is still there, it just takes the sharpness out of the Grado's which I like.
I find the amp to be on the warm side, so if the HD600's are neutral and you have an aversion to treble it could be a fantastic match for your tastes.
I really like the AudioGD amp/dac, it works very well for me as I like a darker more laid back sound, from what you have said I think it should work pretty well for you also.
