USB cable over 5m?


Recommended Posts

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 .

 

How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file.

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

Supra cables - HDMI cables for 4k, Digital Video and Audio, USB, Cat7+ Ethernet, Fibre Optic, Quadrax, LoRad power cables, Sword Analogue and Speaker cables

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.

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.

And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality.

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 !

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.
