Cayin RU6: R-2R USB Dongle DAC with Head-Amp

[dakchi]

The GU Craftsman for the win, with deeper harder hitting bass, more detail and bite in the mids and highs, bigger/deeper stage expansion, and a blacker background. The DD Hifi was very similar to the stock Cayin cable, being a bit smoother in the mids and top end. Now, I am interested in seeing what some higher end offerings will bring. . .

Where did you get it from? I can't find it in Aliexpress

But... it isn't an analog cable... Ok nvm, taboo subject haha...

Let's not go there. I have a feeling I know which camp you are in and it's all good either way.

The amazon photos make the wires look a different color than your earlier photos!
I wonder if that is due to lighting, or whether these guys change the wire material depending on availability (and thus may sound very different)...

Just different lighting. The guy that make cables for GU Craftsman has been using the exact same 6n silver wire for years, and has nothing but positive reviews. I wouldn't ever share a link to a seller that did shady stuff like that.

No mystery here. USB cable should have a 90 Ohm characteristic impedance. If not, you get signal reflections (readily visible on a 'scope) which affect different components to different degrees. Different amounts of shielding may affect things as well. I've tried the OE cables, which use proper USB 2.0 spec shielded cable, and noticed a bit of difference from the stock cable as well. I highly doubt that the braided silver cable is to USB spec, but it something is more sonically pleasing, then I don't see why it would matter.

Is there anyone tried it yet?

what justifies such price tag for a very short cable!

Shielding and quality of materials used in the conductor mostly. It's a common myth to believe that because a signal is digital it has perfect integrity and coherence... this is plainly false.

Its price tag apprx $95 for a Furutech's product. I think it is usual.
Cost comes from both brand and processing tech.

I snagged one of those silver gucraftsman interconnects myself and tried it out, and while I haven't done a/b testing to see if I hear a difference, I have noticed that it's improved the battery life...I suspect the lower impedance of the silver is causing less drain.

Love my OEAudio USB C-C cable as well. No sonic differences noticed, except no iPhone power issues, and less noticeable interference. I will never understand how cable material affects bits... but I guess if you hear them you hear them. Enjoy the music!
