What it is. The Recovery is an outboard re/pre-clocker and power isolator. As such you expect and get USB i/o to go computer-->Recovery-->DAC all via USB. Wyred include a short 6-inch USB cable for the first connection between source and DAC. You also expect and get an external power supply of the wall-wart type since the Recovery interrupts then replaces USB power. Why or how can that improve a DAC already running its own "femto" clock, marketing speak for an ultra precise clock? In Wyred's own words: "The two devices do separate things. The clocking in the DAC has no control over when or how it receives its signal from the sources. The Recovery works to greatly improve the incoming signal before the DAC receives it, so perfecting that allows the DAC to shine even more. The internal clock accuracy and jitter elimination of the DAC can mitigate some of the input jitter but are no replacement for correcting it beforehand."

What it does. Audiophiles being adventurous, the fora are filled with reports of users who slave multiple units in series, say a Regen on one end of their USB cable, a Wyrd on the other. Substitute device and placement. Some even replace the wall warts on their USB fix-it gizmos with linear power supplies. The purpose in all cases is to minimize the migration of noise from the computer source to the DAC; and to lower the work load on the DAC's USB transceiver. Whilst the hardcore tech reasons of the experts elude me, their combined upshot is that working smart, not hard isn't just good for humans. It's good for electronics too. Hence the cleaner the incoming digital signal, the better the outcome of converting it to analog regardless of whiz bang reclocking, jitter stripping and all other chicanery which subsequently go on inside a DAC. If the physical layer of its USB receiver is less taxed because it uses less processing which creates less noise and draws less energy, the sound improves. Reducing computer noise and self-generated noise inside this process whilst improving its packet-time receiving make it so. At least that's the overall gist of the explanations I've read. For the stronger stuff, talk to the engineers.

By implication, all of this goes on behind your equipment. That's where your cables hang off in various states of audiophile dress code. So the Recovery needn't be gussied up in thick chrome or pointy footers. In all likelihood, once it's installed you'll never see it. There's no need or appeal to spend big on casing and cosmetics. Hence the box is solidly made like all Wyred products are but looks nothing fancy. If it were any different, you'd think EJ had sold out. Of course the simpler-is-better mantra bumps up against needing two USB cables. That's twice the connectors, twice their possible losses. Then there's the switch-mode wall wart. It's all set to poison the AC well with nasty ultrasonic noise. Isn't that the exact kind we want to overcome? Oy! As always, arguments pro and con are just a hair's breadth away. In the end, if a bigger fault is cured with a smaller fault plus a grander improvement, it's one step back and two or three forward. To the pro-gmatist, coming out ahead is boss. If the wall wart bugs you, the con-men are eager to liberate your sterling cashish for a linear PSU; and a fat audiophile-approved cord to go with it; and a small platform with isolation footers to wrap it all up. Us, we'll take the country bumpkin approach and use it out of the box; as delivered. Fancy that!
