I'd be very happy for some comments on this 
This is my current setup:
1) ... this gives very crisp and clear sound :-) ... despite it is analogue!
 iMac >> AirportExpress >> Analogue  >> BS9000 >> Analogue >> BL5 
[advantage is that I can listen to music without having to start the TV]
 
2) ... this gives considerably worse sound quality :-( 
 AppleTV >> HDMI >> Beovision7 >> Analogue >> BL5 
[advantage is that I can have music, images, podcasts, movies etc]
 
How can I improve the sound? 
a) HDMI + S/PDIF from AppleTV 
b) Component + S/PDIF from AppleTV
c) What about digital input direct to the BL5s? Can I connect both AppleTV and the AirportExpress?
 (and digital from the BS9000 as well?)
 
Thanx!

PS In what way could a Beosound5 improve the situation?
