Digital Processor Reviews

Now combine it with an Uptone Audio Regen and hold onto your hat.
I am, simply, a VERY happy user. :D

TOSlink tops out at PCM 24/96 and does not do DSD at all.
Hence, IMO, is not a "contender."

If it sounds different and there is no difference in the measurements then either your ears are fooling you OR you aren't measuring the right things OR your equipment isn't sensitive enough. Given the multiple reviews all reporting the same sonic improvements, I don't think you are fooling yourself. So, what do you think the difference is?

Today's measurements devices are more precise than our ears.
A big red SNAKE OIL ALERT should be shown if the gear's measurements clearly indicates no audible (positive) effect.

That makes it a nice little gizmo for the cable drawer if it doesn't work out.

This is Great 1980s Peg Board stuff for the Audiophile shops to help out with their paying Rent.

Back in the Day, little parts like this carried my Esoteric Audio Salon thru slow months of Summer.

Audiophiles love these little trinkets.

Monster Cable had a Full line of his kind of stuff, all were good sellers.

Jason Stoddard at Schiit is the onlyist one that po-po's all this junk.

The rest of us in the Business know fully well that Audiophiles are all about trinkets "moving the performance needle" after they shot their Wad on the Big Gear.

Litz headshell wires, tip-toes, Cramolin, directional Interconnects ( with Arrows ), Stainless, Nylon, Alum. headshell screws, Headshells by Koetsu, Fidelty Research and many others.

I had a 40' Wall of this stuff, all Audiophile rated and specific, it's amounts to a complete product line in and of itself. And, it's at least 50 points, plus nobody returns this stuff.

I even had customers that collect interconnects and speaker cables.

Phew, this IS HighEnd Audio ( the hobby ) : the Neurotic, Psychotic tendencies mechanically enabled.

But now we have Apple iTunes and DACs. Not a lot of gizmo stuff for "the" Wall.

I say: let em have their fun, nobody's gonna get hurt by this thing. Besides it's Audioquest taking over from Monster Cable, somebody gotta make and sell the Gizmos.

Noel Lee at Monster scored his Big with the Beats Headphone, it's time for somebody new.

Hi John, I know the Remedy Reclocker is USD$350 more expensive than the JB and it only does Toslink and Coaxial. But since you have used premium DACs, cables, etc, USD$350 is really not much.

Have you heard the Remedy? Would you prefer it to the JB?

Based on my experience (I also have the PS DirectStream), no single piece of gear (other than Speakers and matching Amps) makes such a great difference as the Remedy Reclocker, assuming one is to spend up to USD$3,000 on gear (I'd rather pair the Remedy with a USD$500 DAC than buying a USD$3,000 DAC and don't get me started on cables!)

Sorry for not talking about the Jitterbug, but they seem to compete.

If there is one question about the Jitterbug I would like to ask, it would be:

1) For my PS Directstream: Do I buy the Jitterbug + a 2m USD$50 USB cable or a USD$1,000 Audioquest USB cable?

Thanks!

IMO if it doesn't pass DSD, it's a non-starter.

I'm running audio files from my computer to the AQ Jitterbug, to Schitt's Uber-Bifrost and Asgard 2, through Senn HD650's, to my ears. JA was right, the music sounds great.

The Jitterbug is unbelievable, which many people will agree, but I say screw the measurements; trust your ears.

I guess the computers JA used had good quality USB.

I can measure the difference in the quality of the USB digital audio outputs of my Mac mini (Late 2012) and my Toshiba laptop (Satellite P-50A). Even when I unplug the power adapter from my Toshiba laptop, the output from my Toshiba laptop is of poorer quality.
(Difference in jitter side bands or in spurious tones? I am not sure. It would be safe to say spurious tone.)

I measure it by looking at the spectrum of analogue audio output (20Hz – 20kHz, 20Hz – 50kHz, or 4kHz – 14kHz, etc.) of the connected outboard DAC. I used two $80 - $150 AD/DA converters sold in the musical instrument market: Behringer U-PHORIA UMC204HD, Focusrite Scarlett 2i2. Each product has both AD converter and DA converter.

Still, it's a nice product that offers an audiable improvement for basic users and for portable machines - that is if AudioQuest will ever snap out of their shell-shock and start shipping it before someone else invents something better - and many companies are planning to...

I have used the JB(X2) on 3 different systems for 2 days: My HiEnd system via a Benchmark USB DAC, my kitchen computer with a NuForce uDAC through Bose self powered speakers and my desktop office rig a Nuforce iDAC through a Zen Triode 3wt. amp.
I sincerely cannot tell the difference enough to make a $49.00 difference.
I have a considerable lot of money tied up in my HiEnd rig and have been doing this for 30 years so it's not about being cheap. Many times I have noticed improvements with various tweaks..
I'm just saying the packaging alone cost more then the JB itself.
This is NOT the way to keep the HiEnd industry on life support.
Perhaps 10 bucks or 2 for 15 bucks might make it so I don't have to pay the return shipping.

Ok, I've seen the measurements and all. I understand that science says this device does nothing, however, my ears tell me different. When I no longer have the sound of my mouse tracking, or keyboard typing, or hard drive working through my speakers.....somethings working!!!! It's dead quiet when not playing media!!!! Sounds better overall as well!!! I don't know what this thing is doing scientifically - and frankly, I don't care - it got rid of the annoying mouse/keyboard noise!!!!! Well worth the $48 I paid for it!!!!
