I would say either the cable doesn't meet USB standards, or isn't exactly 5m and is a little bit longer(maximum length is 5m).

Probably true - if the cable packaging doesn't have USB logo they probably havent passed testing/certification to meet the USB spec.  Pretty odd though as I have hacked up many USB cables, even turned a SATA cable into USB and it worked (not well, but they worked without glitches or dropouts).  Hell even some really goofy audiophile cables can still work in some cases (I don't really want to name names).  Must be some bad mojo going on in those cables.

im tired reading does usb cable make any diffrences or not.  wanted to test it out myself , is there or can i hear any differences between very cheap and a little higher priced "audiophile" usb cables, higher priced cable - dh labs usb cable is also silver coated while other one - supra usb cable is tin coated copper ... but as it turns out dh labs doesnt work at all like one usb cable should work :( btw lenght was exaclty 5m so must be some other problem. but i already got refund. i have no interest to get third broken cable from dh labs so my testing is over for this time :)

I think seeing as 5metres is already pushing the USB spec it will accentuate any flaws in the cable. All my hacked together cables were really short so any deficiencies didn't affect performance in an obvious way like dropout, glitch etc.

Could be bad/cold solder connections. 5m is also pretty long for USB.

i mean there is sound, music is playing but with crackling sound all over the music, 5m seems long yes but there are also 10-15m usb cables, why are they makeing them if it would not work ? :)

My understanding is that USB cable typical range is 3-16ft (5m). However, there are USB extenders which may be active:

How far away from a PC can I put a USB device?

Answer:
With the maximum of 5 hubs connected with 5m cables and a 5m cable going to your full speed device, this will give you 30m of cable (see section 7.1.19 for details). With a low speed device, you will be able to get a range up to 27m, depending on how long the device's cable is. With a straightforward cable route, you will probably be able to reach out 25m or so from the PC.

Soo good that I've found this thread!

On an another forum there were an argument about USB cables used for interconnection between the PC and the outboard DAC.

The topic was: is there any difference between a 99c printer USB cable and a snake-oil-horrendous-price one. The argument haven't finished yet.

Recently read an IT-book that said the digital data consist of packages that have a values 0 or 1, transferred between two points. The only difference could be the clocking of these two components that can interfere.

So really: how can be any difference between the cables? It maybe absorbs the noise coming from the PCs USB interface as it uses switching PSU?

"Either it works or it doesn't" is a motto that applies to a lot of digital audio. If there is a problem, it's rarely a subtle thing. I think people try to carry over truisms from the analogue era where good sound meant dealing with layers and layers of slight imperfections. Digital is much more straightforward.

Agreed.  Kinda nice, though, isn't it?  Remember when you'd grab a fresh pancake of tape, only to discover it was from a different batch than you calibrated with, and you lost 2dB at the top end just by swapping tape batches?  Yup, all the time.  Or how about tweaking record head azimuth to the last gnat's eyebrow, only to discover the right channel was biased wrong, and you had now mis-adjusted the record head az because of it.  Yuck.  Or you wanted to intercut a take from the tail of a reel with one from the head, but your Ampex 350 had so much slip that the takes don't match in pitch.  

 

All in all, we have nothing (literally) to worry about once a cable will do USB2 or USB3, we're pretty much happy campers.

 

OK, sorry, all of that was just an analog vent and purge.

I used to have to calibrate and set custom bias for each and every roll of three stripe mag I ran. I'd get halfway through a reel and check source against playback and notice that a glob of mag stripe came off and embedded itself on the heads. Fun!

I don't know anything about DH cables, but I was very pleased with the 1.5 m Pangea AG cable that I had. Probably on par with the Kimber AG cable. It had less grain in the 5-10Khz region and smoother dynamics over the Lacie Flat cable.

 

I have now upgraded to a Revelation Dual Conduit cable, and I'm stunned at the improvement. Everything said about this cable on the internet is true. Very significant upgrade.

Oh boy. Lemme grab some popcorn.

I use the USB cables that came with my external hard drives. They work great with crystalline clarity and soundstage that is so deep, you can measure it in fathoms.
