Again, a solution for a problem I don't have.

I thought the cable that came with my Music Hall PS2.2 had gone bad because I was getting digital noise on that input. So, I decided to add the JitterBug filter to my new cable order. Well, it turns out I could get the same noise on the old cable and the new cable as they are both loose enough to wiggle around at both ends. The JitterBug did not filter out this noise. I'm sure on paper JitterBug does what it was designed to do, but if I make sure both ends are seated and record silence on both cables I hear and see no difference with or without the JitterBug. Even if I amplify the signal a ridiculous amount.

WOW This made a HUGE difference for my setup. Saga+ preamp - gashelli jnog2 akm dac > usb > pc > apply music I rarely write reviews anywhere for anything to be honest, even the expensive speakers I baught here. My expectations were very low going in for this to make any difference. I also have the Elac Navis Arb51 actives which have now completely come alive. There is detail now and the soundstage gives you chills I am completely blown away. It's like a huge veil has been lifted. This isb what I've been looking for in sound my whole life, you can feel the emotions come out of the music. First time I've ever experience that from a home setup. If you have a similar setup that goes into pc for your music this is a must buy. What's to lose as you can return it if it doesn't help.

Better than ever sound

Improved depth and clarity of streaming Apple Music from my HP computer to my Chinese Denafrips DAC and 25 year old Tandberg amp and pre-amp thru 35 year old JBL 4311B control monitor speakers. Not an up to date system but sounding better then ever.

Really works... smooths out the sound and brings out more subtle detail but I have it wired in empty socket not directly connected, connecting directly makes it overly smooth and you lose dynamics and subtle details but does get rid of harshness if you have a really bright system maybe you'll want to connect directly

Well built, probably worth having

It's hard to tell if this makes a particularly audible difference or not and I imagine its impact will be different depending on how your USB power is and how your DAC is. I think, in my system, where USB power is coming from a UPS power supply to an iPhone, and the DAC is built into a tube headphone amplifier, it makes the music a tiny bit smoother. It seems to just take the edge off the highs and might even clean up some microphonic distortion I'd been detecting in certain passages. To be honest, in this case, tube dampers seemed to help that more. Regardless, it seems to be a good thing to have laying around because when you need it, you probably really need it.

Jitterbug, easy to use and makes some differenxe

For the cost and the ease of use, the Jitterbug was worth it for me. For my setup, which is in a 2020 Jeep Wrangler with aftermarket parts like amp, speaker and subwoofer, as well as Audioquest Dragonfly black, the clarity is noticed most at high volume. I wouldn't say it's night and day but it does feel just a little less fuzzy and is just another part of the optimization process.

Objectively, can't say that I'd recommend this product

Small, compact, easy to use design. Subjectively, I thought it made a slight difference, objectively, the measurements I've seen in testing the jitterbug (AudioScienceReview for instance), it makes absolutely no difference whatsoever. Can't say that I'd recommend it.

Sounds clearer with blacker backgrounds than the original Jitterbug.

Great for PC Sound

Put this in line from my PC to my DAC. I have powerful PC with a lot of fans, so there is a noticable noise reduction.
