Need advise on a new amp

7.1 is usually present on blu-rays HD audio, you will not get 7.1 hd audio thru optical or coaxial
it has to be hdmi

the core tracks are normal ac3 and dts which are mostly 5.1 and on the odd occcasion 6.1, which are ok thru optical or coaxial.
and 99% of 7.1 blu-rays are upconverted audio, there are only a few true 7.1 titles, its abit of a waste at this time.
