I install a lot of Integra's. I haven't noticed any degredation of signal quality. Even on the 'low' end of there reciever line. The 5.5 (msrp $600) also upgrades all video inputs to component, allowing you to leave your tv on same input for all sources.
I've also had problems on 'low end' sony's. You might want to steer clear of those.
Enjoy your H.D.
