Before buying the system I would go to TechnoQ www.technoq.com who have Polk Audio/Boston Acoustics/Denon and also Barzan Digital www.barzandigital.com with KEF/Arcam/Pioneer

You will get much better sound out of a separate receiver and speakers than with that Sony system and also the Polk/Boston/KEF speakers sound much better.

I did the same search over the past week and been to Video Home (LG) as well.
