Does anyone know how many ma's the sr71b puts out per channel to the headphones? It is not listed in the spec sheets I have been looking at.

I meant mW on the last post and not m amps.  For example the VAMP puts out 150 mW at 32 ohms,   Same question on the Portaphile 627. No specs on there sheets.

Don't know, but based on clean volumes levels (when balanced and driving HE-500 or HE-6) exceeding that of the 1500mw DACmini I'd guess it's more than1500mw.  It's pretty close to the output levels of the 2W (32ohm) EF5 amp, but only in balanced mode.
