I've bought an HD600 and my previous daily driver was the Moondrop Aria. To my ears they are pretty close sonically, with the HD600 being only slightly better in almost every way (not including the fact they will sound different as it is a full-sized headphone vs an iem). Noticeably better though with vocals, jazz, and classical type of music.

Well, I'm not sure. I have not tried the 3.5 jack and went straight to balanced cable. And I only follow what their specs says. I have not seen others do a measurement test on it. But based on the specs it will power 1.8v only if you switch to high gain mode. On low gain you will only get 0.9v.

I also just received my cheap dac/amp (Jcally AP10) yesterday for my HD600. I've been using only a dac (jcally ja3) for my HD600 for the past two weeks since I got it. On phone yeah it sounded anemic, but on PC it's almost the same sounding with my new dac/amp if im not mistaken. After some time enjoying your headphone' stock tuning, you should try oratory's EQ if you have not yet. That one became a noticeable change for me.

Thank you for the detailed explanation.

Okay, thank you will try that.

How common or audible are distortions? I heard high gain may have more likeliness to cause distortions
