may I please ask...

Are your speakers still as per your signature, i.e. a 5.1 surround system?

Yes they are.

When playing Dolby Atmos material are the various fly-around and height channels lost, or folded into the 5.1 speakers?

They are folded into the 5.1 sent to the speakers.

Does the Atmos soundtrack sound different from a conventional DD5.1 soundtrack?

Yes it does ...I just ran a quick test with a Dolby Digital Plus with Dolby Atmos music track of James Brown "Superbad" when it's playing Atmos JB's vocals come from above and behind, without Atmos the vocals sound from behind.

With my current connection layout couldn't really compare the Nuprime decoding Atmos verses the Nuprime decoding True HD I will have a futher play tomorrow and run some tests smile.
