"Are these great sounding Computer/DAC systems connected via USB? Is that the only way? And, is it true that USB remains a compromised audio transfer of data to a DAC?"
Yes, USB. There are no technical compromises with USB, just some existing designs that are poorly executed. New technologies always have this effect. Think about the very first CD transport. Complete junk. Now CD transports are quite good because the designers have finally figured out that jitter matters etc.. Likewise some of us have figured out USB.
You can also get great results with networked WiFi devices and a reclocker, but these are typically limited to 44.1 and maybe 96. USB will do 24/192.
Both of these interfaces use packetized data bursts, buffering at the end-point and then establishing a new master clock. Once you have this, the details of the interface are less important.
