I noticed a few weeks ago that AudioQuest announced in their 1st of May 2015 PriceBook a USB Filter called, 'JITTERBUG'. The MSRP is $49. I've ordered 3 of these units.


ABOUT THE JITTERBUG


Dual Line-Conditioning Circuitry


• For use in series with any adaptive or asynchronous USB DAC, USB cable, and USB hard drive
• Removes parasitic resonance — a form of resonant distortion
• Presents a more dynamic and vivid musical experience


Scenario 1:
Use one JitterBug in series with any adaptive or asynchronous USB DAC and USB cable.


Scenario 2:
Use an additional JitterBug in parallel for improved playback performance.


Scenario 3:
Use JitterBug with other locally connected USB devices, such as hard drives, printers, and cameras, to effectively reduce audio interference.


Scenario 4:
Use JitterBug with USB-enabled network devices, such as routers, NAS devices, and streamers.


Scenario 5:
Use JitterBug with mobile devices.

Worth noting. Dan [Double-D] on another forum provided a link to Tone Audio Issue 71 this morning and that the Audio Quest Jitterbug is on the cover.
 
I heard back just now from my Magnolia sales rep about the Jitterbug shipping ETA.

"Ok, I just got a reply from my rep. He said that they plan to start shipping those in the next month or so. He said when he gets into work in a couple days, he will confirm what availability looks like for our stores.

Can I get back to you this once I hear back from him? "

Kewl!
 
Very similar in outlook to the iFi IPurifier ($100) and Larry Moore's Aubisque filter ($200). A bit different is Empirical Audio (Steve Nugents) Short block ($200). All of these are passive devices.

VERY different is the Uptone Audio Regen ($175) which completely rebuilds the USB signal with the aim of stopping data packet noise from being induced in the Dac side of things. Yes, it has reclocking with low jitter clock, galvanic isolation, etc, BUT the aim is to get very high (SI) signal integrity and stop/reduce the Dac's usb receiver from creating new packet noise Dac side. Packet noise does not cross interfaces, but it does induce new noise creation via the Power distrib network and the PHY in the USB interface.

These are all new discoveries from John Swenson, based on a cool working hypothesis. It seems to be paying dividends based on anecdotal user feedback.

As a side note, I think this hypothesis is the best explanation I have seen for why the digi-Lampi circuit in the old Lukasz S-Box based transport sounded so good, even when it was limited to 24/48. He showed how well the digital signal was "squared up" up on an oscilloscope on his site before and after running thru the digi-lampizator circuit. So clearly there are other ways to get high digital signal integrity and all this keeps digital SQ moving forward (without costing serious $$$$).
 
David.......If the Jitterbug actually comes to market at $50.00 I will buy one just to play with and see (hear) if I can detect any improvement in my USB playback. If I don't like it or can't hear any improvement when using it I'll just toss it in a drawer or pass it along.
