Lets look at that a little more carefully. (I was just looking at this myself)
The USB 3.0 SuperSpeed transfer protocol supported by the UAC-2 is ten times faster than USB 2.0 and six times faster than FireWire 800.
So what… this is a two channel device and there are already many 32 channel USB2.0 devices around. Speed is about throughput so no advantage in this case.
The result? Low-latency (2.2 ms roundtrip @ 96 kHz / 32 samples)
Actually, this statement is inaccurate. As discussed above, 2ms of that are just because USB.
for improved performance from your DAW software,
Ah no, actually both 2.2 ms latency and 96k SR will make the DAW work harder to remain stable and still be able to use many plugins. Lets call this misinformed rather than Lie though.
and a stable data stream that is unaffected by computer jitter
Nothing to do with USB 3 and everything to do with the internal clock in the audio device itself.
What’s more, the extra bus voltage carried by USB 3.0 (900 mA, as opposed to the 500 mA carried by USB 2.0) allows for the use of higher-end electronic components such as the advanced preamps and converters in the UAC-2.
a couple of things here, many USB 2.0 connectors allow as much as a 2 amp draw (2000mA) already. Also 900mA is not much when it comes to high quality preamp circuits. And 5 volts is already not enough for many. A good presamp has it’s own (Known quality) power supply. Computer power supplies are about as dirty as can be imagined… Did you notice the use of “higher voltage” when talking about current? can any of the rest of this statement be trusted?
Realistically the only advantage to of USB 3 over USB 2 is that “10 times” as many channels can be transferred at the same latency as USN2.0. If you hold your mouth right…
