Upon further listening to this DAC I must come to the conclusion I don't like it. While warming the sound slightly it drastically reduces stereo separation and sound stage. Track sound narrowed and compressed running through my Hifiman HE400S and are no better through my IEMs. Essentially you get what you pay for however volume levels do get a boost as it's acts as a suedo amp. For the novelty it does make some listening experience pleasurable but personally, I do not care for now it alters the sound signature so drastically and do not like the sacrifice of detail.
