I headed off to Music Direct to buy one. I figured, heck, I can squander $20 or so. WTF was I thinking!?! US$39.00, geez.

If this thing works, my bet would be that it's mainly jitter reduction. Whether of not jitter is a factor in a given situation depends on a lot of things, or so I'm given to understand. My wallet thanks me that I can't hear a lot of the things people claim make an improvement. No, it's true: I'm deaf, at least above 10kHz, plus I have tinnitis. But don't weep for me; it's saved me a lot of bucks.
