Re: New rugged USB 3.0 cables: testers wanted

You raise a point I've never understood: why don't they include some form of error correction in audio DACs like the other devices you mention? Then all data cables that met the standard for the application would/should sound the same. Your point on impedance consistency along the cable and shieldin...

Re: New rugged USB 3.0 cables: testers wanted

With respect to digital signal transmission, I can't say one way or the other, although companies like Audioquest often suggest solid is better. I personally experimented with audio interconnects and speaker cable years ago, building identical cables with mil spec silver plated wire of identical gau...

Re: New rugged USB 3.0 cables: testers wanted

Received cable and 7055C - many Thanks - and am in the process of testing.

With particular regard to the conductors carrying the USB 2.0 signals, are you using stranded or solid-core wire?

Thanks, Thom.

Re: 7055-C noise measurements

Haven't heard it myself, but folks on the PS Audio forum are big fans of the Uptone UltraCap LPS-1.2 power supply for the Matrix X-spdif2, if that helps. What happens measurement wise if you use the aux port to power the USB 3.0 SuperSpeed Isolator 5kV instead of using the USB supplied power? Would ...

Re: New rugged USB 3.0 cables: testers wanted

Hoping to buy the 7055-C soon as well, once the exchange rate improves.

Re: 7055-C noise measurements

Further, how do the jitter measurements compare between the 7054 and 7055-B?

Re: New rugged USB 3.0 cables: testers wanted

CORRECTION: Yes, my Matrix X-SPDIF2 that the Intona is feeding does have the USB 3.0-B port. I'd actually love to try the 0.2 m version to keep the link as short as possible.

Re: 7055-C noise measurements

Ah, interesting point. My DS DAC does not even use power from the VBUS, but mainly benefits from ground isolation. In this case, do you think there would be any improvement over the 7054 with the 7055? Thanks again.

Re: 7055-C noise measurements

Thanks. So, everything being equal, when playing audio via USB 2.0 the 7055-C should be ever-so-slightly better/quieter than the -B?

Re: New rugged USB 3.0 cables: testers wanted

Although I'm using the 7054, I'd certainly like to give the cables a test. 0.5m should do it.

Re: 7055-C noise measurements

How does the noise of the 7055-B compare with the -C? I'm curious because the USB 2.0 is plenty fast for most audio data and the designer of the PS Audio DS DAC claims USB 3.0 ports are far noisier than 2.0 because of the higher clock speeds. (I own the 7054, which provides a marked audible improvem...
