This headphones, I expect a bit lack of extreme highs and lowz and that is fine. It will do a good job within most audible range. The head-amp seems like a good one. Combination of an inexpensive 32 bit DAC, a good headphone amp, plus it is a simple pre-amp. Can't go wrong if someone wanna save money for now or even to drive active speakers..

Actually I am not keen about the earphones.My last one was the Yamaha,connected to the Yamaha 7000 tuner
25 years ago.The tuner was equipped with a volume control.However it gave me a sense of sea-sickness after listening for a while.So I gave up.
