OK, my Pioneer 717 has just died, so I need to replace it and something with SACD and DVD-Audio seems sensible. I already have Sky+ so don't feel a DVD-Recorder is worthwhile (did think about it though!). I see that pioneer do two models but I can't see too much difference between them. both are multi-region by handset, both do all formats. The 757 has the Firewire link and progressive output but as I don't have the matching pioneer amp and my tv doesn't do progressive scan, both these are useless (until I can persuade my wife to let me get a projector and buy a new amp!) Is there any major reason (improved picture/sound) to go for the more expensive one? The 300 quid price differential will pay for the 3 pairs of interconnects needed for the SACD/DVD-A analogue linkup!! Or, is there anything else I should really be considering? In case it helps, I have a Yamaha DSP-A1 amp, with Philips 36" CRT TV, B&W CDM 1SE speakers with CDM CSE center, Kef Coda 9 floorstanders at the rear, and a Rel Strata III sub.
