I'm with Marius, if you an you toss up some jitter measurements comparing various USB cables and how the impact either the SPDIF or i2s streams that would be insightful. I have yet seen a review where such a thing has happened.
BTW, what's on that page that you consider BS when compared to the USB specification? The article provides a light, but reasonable description of bulk and isochronous transfers that line up with the USB spec, so they do indicate there is some cause for concern with cables. They quickly disprove that by showing no detectable transfer errors with either cable and the reader now knows the data will arrive safely for any good cable. They even provide the user with a method to test errors on their system. As I mentioned earlier they didn't provide any jitter measurements, both sad and typical for any audiophile magazine. What I find alarming are the manufactures that claim improved sound by reducing jitter or increasing reliability, both of which would real easy to test, the price tag attached to those unproven claims.
The article doesn't discuss synchronous, adaptive vs asynchronous USB DACs, and their effect on clock regeneration, but it did seem like they were attempting to head down that path, they briefly discuss it here
http://www.alpha-audio.nl/2011/06/de-usb-kabelmythe/. On a side note, both articles do a reasonable decent job dissecting the Tentdac b-Dac while explaining some of the USB audio jargon.
Continuing the side note, the Tentdac b-Dac uses a few mature chips that date around '03 and updated in '06 in the design: PCM2702 which is an adaptive USB to I2S/SPDIF converter and DAC (PCM1792) if one wanted to read the data sheets at Ti.com. If any USB cable would shine over another seems like the b-DAC would fit the bill with the 48/24 max USB port. Of course the B-Dac's linear power supply and with it's extra detail on retiming the PCM stream from both USB and SPDIF inputs make it a solid Dac.
I do think most USB Audio fan's would discount the USB port on this product since it's limited to 48/24 playback. If you like to mod hardware, this DAC is rather interesting, you can ask for different output stages and even the clock used to time the i2s signal on either a 44.1 or 48 kHz multiplier.
