The Onkyo certainly ticks your boxes but so will several av receivers for under £200 2nd hand. Just look at hi-fi/video review sites and look for previous years best buys. Sometimes you can still find them new for a fraction of the price of when they won the award. It doesn't make them any less good. I've seen 2007/2008 best buy £1000 receivers sell for £300 new nowadays and hence much less 2nd hand. You can certainly buy what was a full great sounding system which cost over £1000 for under £200 2nd hand.
Onkyo key specs in relation to what your after:
DTS-HD Master Audio, DTS-HD High Resolution Audio, Dolby TrueHD, Dolby Digital Plus Decoding
• HDMI (v. 1.3a) Audio and Video Processing
• HDTV-Capable HDMI (2 Inputs and 1 Output) and Component Video (50 MHz) Switching (3 Inputs and 1 Output)
• Bi-Amping Capability for Enhanced Musicality and Power
DTS®-ES™ Discrete/Matrix, DTS® Neo:6, DTS® 96/24, Dolby® Digital EX™, Dolby® Pro Logic IIx
• H.C.P.S. (High Current Power Supply) Massive High Power Transformer
Independent Crossover Adjustment for F/C/S/SB (40/50/60/80/100/120/150/200 Hz)
And later decent surround speakers sets are even cheaper to buy as on ebay they are collection only normally and go for a song.
My speakers were probably over £500 when they were new.
