Cerious Technologies Matrix USB cable

@lprules1962 What's the dedicaded USB card that you're using? I have a JCAT Femto USB card powered by an LPS and it's quite transformative of my system. Apparently, the JCAT Femto network card with an LPS is more crucial to your setup than the USB card. Having both would be ideal. 

@rgrost I'd like to offer my services as a beta tester for your USB cable as well. I would need a cable at 1.5 meters or greater and it would be tested on a computer with a dedicated USB card powered by a linear power supply. The cable would connect to a USB powered diyinhk dxio pro3z that feeds a custom tube dac. My system's amp is a Pass XA25. 

You’re welcome. That USB card is one of the best values that I’ve come across in this hobby next to V-Cap’s new ODAM capacitors.

I suspect that the culprit to your USB problem is your current USB card. It may be faulty or low quality. Have rgrost send you the original "faulty" USB cables when you install the new USB card to see if the problem persists.

I’ve encountered the same problem before when I attempted to upgrade my computer. It wasn’t the DAC nor the USB cable that malfuctioned. It was the motherboard’s USB connectors. The JCAT USB card took care of the problem once and for all.

You should consider the fact that the problem lprules1962 had with your USB cable was an isolated incident. It's also possible that your 1m cable would not have worked in his system either.

I'm quite sure the problem stemmed from his Sonnet Allegro Pro USB 3.1 card. My Stealth Audio USB T-Select cable doesn't work on my computer's USB 3.1 outlets either. I used the USB 2.0 outlets to A/B test the JCAT USB card.

With all due respect, I think it's too soon for you to limit your USB cable sales to only 1 meter in length. You should evaluate the issue further with other customers that use completely different systems just as you did in your own system.

lprules1962 now has the JCAT Femto card and it shouldn't have a problem with your USB cables at any length.
