“…I put the iFi Zen dac/amp v2 up against my Schiit Hel dac/amp (this unit DOES have support for a mic for gamers) and the FiiO e10k dac/amp to see which unit would come out the winner in terms of pure sound quality. The Schiit Hel is priced around $200 and the FiiO can be bought for around $70-80, which puts the iFi right inbetween the two. I did not experience any of the issues other reviews have noted on Amazon, specifically mentioning one headphone being noticeably louder than the other.
The iFi blows both of these units out of the water in terms of sound quality for me, in my subjective opinion. The True Bass button is pure bliss. The lows in the bass are much cleaner and more pronounced compared to the other two units i compared the iFi to. The FiiO does have the equivalent of the iFi’s ‘True Bass’ button, but for me, the bass lacks on the low-end on that unit. The Schiit Hel does not have any bass feature/switch like the FiiO and the iFi, so the bass, for me, is lacking a bit on this unit…”
