Curious: how much headroom do you get with those? This has been the big downside of most USB audio devices I've tested, including those with balanced I/O: they max out at around 0 dBm. This is largely due to the limitations of the USB power connection (+5 vdc @ 100 mA max), whereas a true 'pro' balanced output requires a bipolar +/-15 vdc power supply to achieve the accustomed headroom of around +20 dBm.
