Rather than comparing a cheap passive attenuator to a expensive attenuator, your comparing a 50k pot to a 10k pot, what about the goldpoint-sa2x compared to a cheap 10k pot attenuator like the jbl nanopatch.

Topping dx3 pro .

Anyone know how these compare to there main competitor the edifier s1000db?.

XDUOO X20 , is cheap and has loads of features , measurements here: https://reference-audio-analyzer.pro/en/report/amp/xduoo-x20.php .

The jbls are pretty good http://noaudiophile.com/JBL_LSR305/

The 2.1 in the box systems aren't the best, the budget 1's are just awful, the high end 1's are much better but for the money you can get better performance with separates. speakers...

Why do the golden ear crowd like such pricey badly engineered low fidelity gear like https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-audio-gd-r2r11-dac-amp.5779/...

Trap

The usb in a dap and pc are built to the same spec otherwise you wouldn't even be able to copy files to the dap. Like you say theres 0 evidence a dap or pc sound different over usb and a cable certainly won't change anything. Both should sound transparent. The dap has the advantage in couple of...

Apparently now to determine whether theres an audible difference between usb cables we need code?. Measuring thd, jitter etc isn't scientific enough, even though the tests are repeatable and 1 was done with nearly £3000 hardware that is even used by the manufacturer's of dacs.

His gone from trying to convince us usb cables make a audiable difference, to no one could possibly know.

I'm only interested in how a usb cable would affect the sound quality we hear ,so we would measure , jitter , thd , signal to noise etc. These measurements have been posted and show no audible differences to prove otherwise you need to post measurements or any objective data rather than just...

102 pages and no objective data showing usb cables having an audible effect. Just the usual rubbish about science doesn't know everything and can't prove anything.

Psychology is the only way to make sense of this site, go and read some of the threads in the main forums there is some very strange cult like behavior going on.

At least after 99 pages we have all finally reached an agreement.

So the only time a a usb cable makes a difference Is when the dac defective spending silly money on a cable to fix the problem is madness replacing the defective dac seems like the most logical solution , measurements show even the cheapest cables work fine and are the best performance your...

I think as it was pointed out a few pages back to even perceive the ultrasonics they have to be a at a really high spl a spl level you wouldn't listen to music at because your ear drums would explode, ultrasonic content is inaudible and un perceivable in music playback.

Theres no chance a cable is gonna effect ringing since it has no oversampling or reconstruction filters, we are left with noise , distortion , frequency response and timing, what parameter do you think is missing where the cable would measure a audible difference?. Obviously the person you...

You've just dismissed all the objective data supporting theirs no audible difference between usb cables, but haven't provided any that supports your argument that there is.

Objective data shows theres no audible differences between usb cables, http://archimago.blogspot.com/2013/04/measurements-usb-cables-for-dacs.html . Even with a poorley designed dac highly sensitive to power and USB conditions the cable has a larger effect but still not audible...

They have a low impendance only 28ohms, so require an amp with a low close to 0 out impendance, to get them to sound there best.

Would an upsampling dac have less ringing than a standard dac with a standard filter, since upsampling dac use different filters with a slower roll off.
