Here's another thought, along the lines I mentioned.
You could buy something like a newer Harmon Kardon (Stereo Dave's in Oregon Mod's these, also) AVR 247/347, with DCI Faroudja processing, 1.3a HDMI and Dolby HD and DTS Master, 1080p vid switching, EZset Parametric EQ (tune out the nasty peaks in your room), same 100db sig/noise specs as the Arcam,
multi-channel inputs, and and overall superb sound quality in an otherwise budget receiver line!
Actually, the tonal qualities, clarity, detail, and lack of coloration (even similar warmth range - although the HK is a tick warmer, if better balance I think) of these stellar sounding little Av receivers is superb! I think the best around for mass manufactured AV receivers, personally.
You could then spend a few hundred bucks buying one of these, and add a superior set of amplification with a used mult-channel amp! (which, BTW, will stomp the amps in any receiver with careful selection. Plus less electro-magnetic interference, less noise in the sytsem, better dynamic range, etc). Not to mention, yes, you can get these moded for even more refined sound!
Anyway, it's a consideration to your all-in-one solution, with older technology you're considering.
Personally, I wouldn't consider any of the older receivers, with no current tech EQ, no HDMI 1.3a, no HD codecs, No 1080p vid(???), and limited power, ideally, etc.
Maybe this helps, maybe it doesn't. But it's more info to toss around
