I'll make one more comment and then leave it be.
I happen to think $1,500 is a lot of money for a DAC, and I could afford to spend more than that if I thought it was worth it. Others might see $1,500 as quite reasonable. Part of it is conditioning and expectations, value judgments, and the size of your wallet.
Numerous factors affect the price of a audio components. Performance is one of them, as are aesthetics, features, design, complexity, etc. But I also believe that as the price goes up performance becomes less and less a factor in the cost. At least that has been my experience.
Sometimes we spend more because it increases our confidence that we are buying a component that will deliver the goods. I've done it myself. Visually attractive aesthetics, robust and overbuilt designs, and extended feature sets can help to build confidence in the product. But that said, those things may not sound any better than a lower priced component.
I personally believe that in the absence of an in-home audition, you are pretty much rolling the dice on any audio purchase.
