Gremlin is a hit!
I just received my Gremlin. It is clever as hell. Cute too.
I just started to listen to it with a Geshelli DAC and WIIM pro. After swapping to the better tubes, I started to really listen. It's great!
I'm driving Hifiman SE1000s. Plenty of power and sounded great. I just ordered ZMF Bokehs closed back to try a different setup so the Gremlin turned out to be a lot more expensive when you add the new gear. But I am excited to listen again.
