As a dealer, I can buy just about any cable I want for my own personal use. I have several of their cables scattered across several systems that I paid what everyone else pays for them. That ought to speak for something. I did buy them during their sale periods, though.
I have the upmost respect for Cobalt and quite frankly hate to see they are out of business. Their build quality was excellent, they were dressed much better than so many others out there. I've recommended them many times to my customers, even sacrificing a sale because a customer was not wanting to spend a lot of $$$ on cables.
As for "snake-oil", yeah there is some of that out there. But, you got a quality cable in a very pretty package with Cobalt. I like pretty, so I don't mind spending more. Not a fan of Home Depot lamp cord. I don't care if it sounds fine, I still won't use it. Call me stupid, I don't care.
