Anyone tried Corning Optical USB cable?

Looks like AQ JB does reduce noise:
I don't understand the eye pattern graphs, but I do understand the final chart. Is the reduction in noise audible to you?

Archimago did.

I don't think most pirates will value his opinion though  :)p8
Then there is a sort-of follow up including the corning.
http://archimago.blogspot.com/2015/05/measurements-usb-hubs-and-8khz-phy.html

Only the data is transferred through 'real' fiberoptics, which has advantages, as in no impedance problems for longer hauls and no reflections in the cable itself.
The ground is still hardwired via copper (the +5V computer side is used to power the FO receiver end but not connected to the USB out)
So there is no galvanic separation which would have been nice as it is an asset to FO, the data is 'reconstructed' on the receiver end but no idea how (well) this is done.
Also no idea on how well impedance matching is on the receiver and transmitter side of the electrical interfaces.

From what I understand, the corning does not have enough power for certain dacs that require power from the usb cable.

It will be interesting to combine the Corning Optical USB cable with Schiit Wyrd after it.

USB Port > Corning optical cable> Wyrd > USB cable > DAC

Corning will send much cleaner(less emi/rfi) signal due it's optical signaling to the Wyrd, which then will supply it's own cleaned power and clocking to the other usb cable.

most pirates won't agree, but there's certainly some truths behind sonic improvements made by usb audio gadgetry.

Do you think there may be an acoustic leak from the jack hole? ~Tyll Hertsens

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin

But the eye-pattern got worse.

This why when I hear people say it sounds 'better', my instinct is interpret that as 'different' or 'preferred'.

In my applied subjectivity, 'better' must usually improve upon and retain what was there, not trade off in zero sum format.
