Replaced an older Sony unit -- Fit into current rough-in flawlessly.

Manual is good.

Unit works as advertised and has performed flawlessly.
I like the various sound profiles and adjustability if I want to "customize" the sound output.

The amp seems to drive two sets of speakers at volumes that I'd never challenge.

Only grip: The off button is a bit "obscure" compared to what I'd expect; and, the CD advance tracks is a bit non-intuitive
