I am looking to purchase an amp which will be used primarily for movies via sky hd, wii games and music via iphone 4. I would also like to future proof for a possible 3d tv purchase. I have narrowed it down to the Onkyo 578 with the UP-A1 ipod accessory and Tannoy SFX 5.1 speakers. Questions: Any other suggestions out there? Budget is £600 ish? Is the UP-A1 compatable with an iphone 4 - the manual only states iphone oe iphone 3g? Does the UP-A1 transfer video and photos to a large tv in good qulaity (I will be connecting 50 plasma to am via hdmi?
