Suddenly last week the wireless features failed for no reason

Great features.

Good features

The night sound is a nice feature to normalize volume and the speech enhancement helps with the dialog as well

Being able to seamlessly run music through the system is a great feature as well.

Tried the Zvox 670 (muddy out of control sound) and new Samsung MS750 (decent sound, good features, weak bass)

and it's an easy install, as well as being nearly invisible under your TV.
