Okay, Kim, I haven't looked, but maybe that's what they mean by devices; if so it doesn't have much meaning.

No, the Denon Link is proprietary and, as noted, works only with a couple of their most expensive players.

That difference in THD is far below audibility. Results vary slightly, but blind listening tests indicate that when using music(not test tones)THD doesn't become audible until it exceeds about 1.0%.

Enjoy the music, not the equipment.
