AudioQuest JitterBug USB Filter Review

Full Ack.
Galvanic Isolation of the digital input side of a DAC is 100% guaranteed to always eliminate all "ground loop" type of issues, as it fixes the root cause of the problem.

why they dont include it, i really dont understand. Marantz ND8006 had same issue with my pc as well, same shit noise all around. It's an expensive product but even in it there's no isolation at all. Amir probably used a laptop on battery therefore couldn't observe any difference.

Capitalism encourages profit above all other factors. We should not be surprised that companies take advantage of buyers with more money than sense. This is what they teach at Harvard and Stanford business schools.

The only thing about Capitalism that appeals to me is competition. With some legislated controls, the "profit pirates" will take advantage.


Has Amir tested other USB "cleaner" kit, for example from iFi?

I am still thinking that Amir's tests should be of several sources (PCs Laptops etc.) to see if there is any noise before/after (rather than the effect with several DACs).

EDIT: I see that this review from Achimago addressed the attempt to attenuate "noise" from a NUC

Capitalism makes everything that we enjoy in our lives including this entire industry.

Every form of government takes advantage of stupid people; the idea is to not be stupid.
Anyone who thinks that other forms of markets create better products; I encourage them to show some examples of such innovative ideas and competitive products without any such incentives to do so other than "mandates".

As far as the performance of the product is concerned, if it can eliminate any noise whatsoever, then it should actually eliminate the noise that the system is producing because every electronic device has noise.
However, I do understand what you mean by systems that have large amounts of noise where things like USB can not even be used. I can personally tell you that I did try a couple of these devices in a system that did have that problem and they did not fix it at all.

Three thumbs up to you for that post @Jimster480 !
And I only have 2 thumbs.
