Quick Audioquest Jitterbug review

I usually try to stay openminded. There's a reason for everything.

I guess nobody questions the USB related issues - noise, data jitter,....
I'm not questioning Sjefs experiences either...

If and how USB related issues impact your audio experience is one story.
What's causing these is another story.
How you can fight them would be one more story.

Anyhow. I figured, things are much too complex and differ from setup to setup.

For me there's no other way then try and buy.
Try 14 days and if you don't like the stuff or if it doesn't work it goes back.

Cheers

If you are going to design a filter for HF noise then it should be designed correctly, capacitive coupling will just negate the filtering.
But its a whole new market to milk the gullible of their money....
Of course some real research and information would be interesting from audio companies...
The Wurth connector has the common mode choke, the ESD device and a Pi filter for the 5Vs, nothing earth shattering, just allows designs where this is lacking to retro fit the connector to add the extra filtering or to save space on board designs.
Digital is the new Audio demon, and luckily for the suppliers of this sort of stuff signal integrity, noise issues etc. are not really understood by most audiophiles so scare stories and myths of how bad it all is creates a market to suck more money out of the punters.....

The usual BS marketing quote, how can you put the analogue back into a digital signal (and don't bother boring me with digital signals are analogue, I know but it does not matter at this level, only when you are doing serious signal integrity work), its like the claim silver USB cables sound brighter....
The specially-designed circuit restores the ‘signal waveform’ and puts the ‘analogue’ back into USB audio for a true, life-like presentation.
 
That's nonsense.

Usually "Audiophiles" tell that there is a difference. They are not scared. They just try it.
Then the "snakeoil-prove-it" fraction shows up. Questions everything. "No measurements - No difference"

That's the nonsense never ending game.

If somebody shows up with measurements, these basement-dungeon I-know-everything-better engineers rip even those apart. Why? Because it is possible. And that's the game.


Bottom line. I'm outta here.

Enjoy.
Unsubscribed.
 
No its not nonsense its reality, maybe if some factions of audiophiles got a bit more real things would move forward.
The whole point is to prove a hypotheses, then it can become a theory, until then it is nothing but speculation.
"bottom line. I'm outta here" = you are not a believer I will not discuss this.
 
As I said. Sometimes it works, sometimes it's neutral, sometimes it makes things worse.
There are several factors - and it's always the sum of these - leading to this or that result and conclusion.

If they advertise the device as the universal cure - as you say - they are most probably wrong.
As much being wrong as advertising asynchronous USB as universal cure for every USB Audio associated issue.
But that's how marketing works!

I do also own a RME Fireface UCX. In my case a USB filter and cutting VBus makes quite a difference. And that applies no matter if I run the RME from my ARM streamers (Cubitruck/PI) or my desktop PC. (I'm running the UCX into Adam A5x)
I do have to admit that the improvements became more prominent after I swapped the
rather mediocre power supply of my UCX. -- They' would have killed me if I'd post something like that in the RME forum.
Not to forget. USB cables can also mask tuning effects. You won't get around identifying all the bottlenecks in your chain(s).

Obviously we need to put this discussion into perspective.
Nobody expects such a device lifting your $50 DAC with a $2,5 cable into audiophile spheres.
You might end up with a bit less grain, slightly better dynamics, better separation, blacker black.... ... the ususal.
The more resolving your system, the more you're focussd, the more you'll notice. The usual.


I wasn't even talking about audible differences, I was talking about if it primarily works or not. In most cases I (and my friends) had errors that there was sopmething wrong with the audio device, or that the device was not recognized at all or when it worked there was a lot of distortion with the jitterbug in place. We never even got to the point of listening to any audible differences at all. It simply did not work in the first place, that;s wehat I'm talking about all the time. Not about how resolving a system is to hear the difference, it just has to work before going into that territory. In two cases it worked flawlesly out of about a zillion combinations, that's not what I would call a good score. All I'm saying is that this is absolutely a try before you by device.
 
I'm back. 😀

@phofman. Please don't try to play the smartass here.

The discussions were not just about latency! These where about latency, latency-jitter, data-jitter, constantly changing (SW) load conditions that also impact power supplies, power rails and noise.
And it was me against the rest of the world.
Bottom line - at least to me - there's nothing new on this still ongoing discussion.

Meanwhile there are are numerous audio players and audio distros out there claiming
"audiophile" music playback on all platforms. Volumio, Rune ,Moode, Voyage, AP-Linux,...Most Linux based stuff - you'll find them over here at DIYA - is using MPD as base. You'll still find my 2008 MPD HowTo in the DIYA oldwiki area btw. - The recipe remained the same.

Numerous users are supporting these "better sound" claims. Nobody can really explain it. Nobody intends to measure it. They just enjoy it.
Only die-hard naysayers put all that into the placebo corner.


Just to get billshurvs preoccupied conclusions straight.

Attkinson clearly says that he's not able to correlate his measurement results - which in fact show slight differences - to what he hears. And he states that he clearly hears differences. ( I and 1000s of other USB filter users wouldn't doubt that -- yep, I know - It's all placebo.)
He also states that his measurement gear wouldn't cover issues in the digital domain. I doubt that it would help anyhow. In the end somebody would have to explain how changes in the digital domain translate into changes in the analog domain.
Everybody who'd try to explain it would face shitstorms - as usual. I'm not surprised that you won't see any measurements from those selling these devices. The problem they have to face - If you say anything you'll be nailed, If you don't say anything - you'll be classified as quack. The only way out: Try and ( Buy or Return ).

This will go on until somebody finally nails the subject. I promise, we'll have that very same discussion over and over again until this happens. That's the game.

Enjoy. I do.
