Looking forward to ASG-1.2 reviews. I almost sent mine in for the upgrade but I want to hear how treble is affected first. Still really enjoying these with EQ. Brain burn-in has me satisfied with a less drastic treble lift than I was initially using, but most people would still consider it pretty steep. These iems could really explode in popularity if their mountain shaped frequency response could be turned upside down, and I mean that in the most encouraging way possible. There is just so much potential here.
