Roy turned me on two the Monoprice SlimRun. At the price and the return policy, it was a no brainer to try (I definitely have a bias for optical isolation). For me 90% of the benefit has been the freedom to place servers and DACs wherever I want them.
When I first tried with the Extreme, I found that I needed to power the Monoprice SlimRun with a LPS 1.2 to get to a happy place. Externally powering the Monoprice is a must for me.
On my to do list is to hack up a SlimRun to power the DAC side of the cable directly (get out a drill and soldering iron and put a DC connector on that end). TBD what lift there may be, but right now Vbus DC power is running 30' along a very thin wire embedded in the SlimRun cable. Getting true galvanic isolation and shortening the DC distance with better cabling should net to the positive, but the proof of the pudding will be in the tasting.
There are other optical USB solutions as well. I have not had a chance to spend time with them, so I can't say how they stack up to the SlimRun.
