I've had these for just over 2 weeks now and I just can't put them down. The sound is very, very near AB-1266 TC with a touch of Susvara. I'm running these with the Hiby RS8 and it is an amazing combination. So crystal clear in all frequencies. Massive and detailed bass impact. Very satisfying.
MusicTeck is a great store for this, and much more. I also bought the L&P W4 for times that I won't have the RS8. Detail from this to MacBeth is stunning. Only slightly less bass impact compared to RS8, but still very engaging. Very crisp and clean sound, unlike any USB dongle DAC or IEM I've heard to date. The moment I heard this combo from my friend's travel case I knew there was no way I could Not get these. You simply can't go wrong, get these now!
