Great bargain amp

I you want an affordable desktop amp with plenty of power, the DX1 is great. This is powered over the same USB cable that provides the audio, and it only outputs single ended ( both 1/4" and 3.5mm ), but 280mW x2 is pretty good for all but the big boy planar headphones. I typically use this for IEMs, and rarely go above 40-50% on it. The next step up is probably the DX3 Pro+ ( which is about 2x the power and twice the price ). I really like the AKM DAC chip on it.
