USB cable over 5m?

[Guido Del Giudice]

I would like to connect my Mac to a Lead Audio NF DAC-384 using a 7m USB cable

 

I also have an iFi USBpower so the power supply would be separate for the USB signal

 

Before I go and search for a quality 7m USB cable is this even possible?

No. The USB standard is for 5M maximum without a USB extender, which if used is likely to cause increased Jitter which will quite likely degrade audio quality .

Why not try it and see?

Standard is standard ... but I noticed Supra produces USB2.0 cables of 0.7m, 1m, 2m, 3m, 4m, 5m, 8m, 10m, 12m, 15m lengths.

If anyone is using lengths over 5m, with or without active extender: what are your experiences?

Correct ！ This is the only right choice that far superior than other solutions

The Corning is excellent in this application but it is not the only solution. Side-by-side, I have a 30' Shunyata that is equal but different.

[AnotherSpin]

I use Corning Optical, no issues so far.

ok, ordered....will report back

That looks similar to those Monoprice has. Those work up to at least 82.5 ft (25 m). I have a 15 meter one I use all the time. No issues at all. 192khz/24 bit no glitches, dropouts or any other problem.

Perhaps that explains a lot ? (grin)

The best USB cable is no USB cable, or the shortest possible USB cable ,with wherever possible no noisy +5V from the computer in it !

No. The USB standard is for 5M maximum without a USB extender, which if used is likely to cause increased Jitter which will quite likely degrade audio quality .

 

That is the maximum that guarantees you standard USB performance. But I've successfully used a 7m cable without any problems. However, knowing that I was exceeding the standard, I did buy a better than average cable.

The problem is that not all USB cables, despite what they may have printed on the jacket, are really USB 2.0 compliant.

I have seen USB cables where the data and power leads aren't individually twisted pairs, and a 5M long USB cable that didn't have any screening (!!!), presumably to reduce capacitance and make sure it worked.

That was my point about buying a good cable.

He can safely use a USB to CAT5e Balun to extend the run. The DAC will reclock the incoming signal and successfully remove jitter therefore successfully reconstructing the data-gram.

I've used, multiple times, both USB and HDMI extenders with zero issues.

I haven't tried this one but I trust Tripplite:

I got this one and it works perfectly
