AQ Jitterbug for USB


Has anyone had an opportunity to try one? It's supposed to reduce jitter and received high praise in Tone Audio. Isn't the iFI iPurifier a similar device? There was no mention of it nor was there a comparison. I'd be interested in knowing whether anyone has compared these two devices.

Jc - do you know where it can be purchased? I found an AQ price book on-line dated May 2015 and the Jitterbug is listed there w/diagrams on use but haven't found where to buy it.
