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.
I own the iFi purifier along with the IFi usb power supply and dual headed usb cable. It does add refinement and is certainly worth the small costs.

I read the same article in Tone about the AQ Jitterbug and I am tempted to try it.
I'd like to try it too esp. as I do a bit of headphone listening with a Mac (Dragonfly v1.2 into an Asgard2). Should be easy to tell if it improved things.
