You may be reading this review, unsure what to make of this Amp, asking how can a cheap sub $200 amp offer the power needed for an expensive Headphone such as the Hifiman He-500? If you have done your homework you will find this is the stereo amp everybody is...” --fluidz
“ The sound from my iPod Classic via The Total Airhead into my Shure SR440 headphones are truly great, and with four AAA-batteries it's an acceptable playing time too.

“ A couple of years ago I had a big amp like this one but one with 4 headphone inputs and sold it on headfi. I can't remember very well how much difference there is between balanced operation and unbalanced (I only remember there was a difference in sound level - when I listened to a balanced and unbalanced HD650 both at the same sound level then the balanced HD650 phones sounded a...” --alexdemaet
