Agree, USB3 has higher chance to run into compatibility issues. (After installed USB3 PCI-E card to PC, you need to download specific driver for this card, and the driver often run into trouble supporting USB2 and even USB3 devices. From my experience, usb3 == trouble)
I don't see the benefit of using USB hub, or USB PCI-E card. I guess Gary's intent is to let all DACs connected to the computer at the same time. But when A/B switching the DAC, you still need to go to computer settings / playback software settings and select the new device. That will cost 5~10 seconds.
I would rather only keep 1 DAC connected to the computer, and unplug, plug usb when switching DACs. This will only add extra 2 seconds (on top of the time needed to switch software settings).
