Audioquest Cables and Jitterbug

Are many of you using Audioquest Jitterbug(s) with your USB cable?

Unrelated but same company: Has anyone purchased Audioquest cables on E-Bay out of Hong Kong and not received counterfeit cables. One seller has been there for six years and only complaint was the shipping time due to DHL.

All input welcome.

Re. Jitterbug, from the Audio Science Review …

I tested the jitterbug before forming ASR Forum. It came free with my iFi iDAC. As you can imagine, it does nothing.

See the audio analyser test results on page 2 of this thread. Even if it did do something I doubt that it would do anything a respectable DAC isn’t already doing.
