I see most DAC/Amp recommendation are the same as those for the Mad Dogs (The Schiit stack, iBasso PB2/DB2, etc.).
That's a bit strange since the voicing of the Mad Dogs and Alpha Dogs is quite different from the previews ("LCD-2 like" vs "HD-800 like").
These gears are commonly described as lean or bright sounding - which might suit the dark MDs particularly well, indeed - and I doubt these would be recommended for the HD-800 (for their voicing)
Did I miss something?
I'd recommend the NFB-28 or NFB-10ES2, too.
