My GOODNESS

This is perhaps the best sounding bit of amplification I’ve personally heard or owned. It’s as if you’re hearing a new, higher resolution. Everything, note weight, instrument layering, imaging, clarity, bass, it makes my IEMs sound like new and more resolving sets. It even runs Joal to this outlandishly timbre centric our sonic Utopia. I cannot get over it or enough of it. I’m descending on a plane as I type and it still sounds like a different beast entirely.

I’m going to see what fireworks pop off tonight when I run it like out into Sigma Pro.

It ain’t just another dongle ladies and gentlemen. Just buy it.
