The Teac has now arrived. Setup required installing a kernel extension / driver of some sort. (Without a driver, it would start playing, but would rapidly wander off into weird distortion, like it didn't know what clock rate to feed the data into the D/A.)

Overall, seems like a solid box. And it's got a U.S. warranty, versus needing to ship back to China...

At this point, it now firmly shows me that my 20+ year old bookshelf speakers (2-way Paradigms) aren't all that good any more (boomy, muddy, etc.) and need to be replaced. Sigh.
