Mine right now is
LG PK350 50 inch 1080P Plasma
A used Denon AVR-1910 amp but its a lovely sounding amp.
Very musical think I even like it more than my stereo one which is a NAD C370.
The NAD C370 seems quite boring now where as the Denon AVR-1910 I seem to here more detail in any music.
NAD C370 uses Wharfedale XARUS5000
And my 7.1 set up is kef carina 2 4 speakers , KEF Cresta Centre Speaker SP3322 which seems decent to me.
The back surrounds are JVC SP-E5 which don't have no bass response but is fine for back surround effects.
Sub is an epos els and a SONY SA-WP890 for a bit extra.
I have had
Pioneer VSX 817
TEAC ADG 200
And the AVR-1910 is the best I have heard yet.
I use a Sony RDR-HXD890 for PVR and an 80GB Fat PS3 for Blu Ray.
For downloads I just connect my PC.
