Another great review by Brooko, thanks!

Looks great, thanks!

Any chance that using the line out on this would be noisier while connected to power source than the dap alone running from battery? 

I can't see how it would be. Might show up on a scope - but doubt it would be audible.

When I plug the X5ii into the dock the digital coaxial output is muted, so you can't use this dock to integrate your player with your hi-fi. This is a major floor and means the player has to be removed from the dock to play music through my hi-fi.
