This is a perfect transportable amp with size similar to Hifiman HM801.
When couple with a Sansa Clip, the sound quality beats my previous HM801 w/o external amp.
It drives all of my headphones very well, including LCD-2s, DT880s/600ohm and Westone ES3Xs (IEMs).
Overall sound quality is easily at the same level of full size amps costing around $300-500 USD. It does not seem to add any flavor to music, more like wire with gain. Very transparent.
