This amp is only 3 months old and has no more than a 150 hours on it. I bought it in Satin Blue. The retail price for this amp is $3000 and I'm selling it for $1700. I'm only selling this because I found an amp that I find more enjoyable. If anyone is interested, I also have a HiFiMan HE-6SE v2 with hex grill mod that I barely use that's in almost like-new condition, which I could throw in for an extra $300. The HiFiMan HE-6SE v2 used to retail for ~$1699 at one point but one could usually buy one for ~$650. Let me know if you have any questions or need more pics. I have all the original packaging for the GS-X mk2. I live in the Washington D.C. suburbs so local pick-up and auditioning, is available.
