Oh I'm sure the quality is excellent and there's no doubt it's not garbage. But for what it actually does $600 is pure ridiculousness
By comparison I just picked up a Schiit Jotunheim and Modi Multibit for about $600. No way this one little device (basically a dongle) is the same value as a stack like that in my playbook. Don't defend companies who want to price gouge loyal customers (ahem Apple) it only encourages the practice. Good idea. Ridiculous price.
I agree that the price is ridiculous and despite Chord's unwillingness to sacrifice quality, there is definitely price gauging here. You can argue that they need to make money but they would also get more sales volume at a lower price. I would love to have this but can't afford to pay the same price I paid for the Mojo, just to make the Mojo wireless.
However your comparison of products is also ridiculous, this is a a solution for a portable rig, and as such your Jotunheim and Modi stack has zero value to me, for example, vs the Mojo and Poly.
