I guess this would be possible - but I have a Pioneer LX08 for Blu Ray and Arcam DV137 for DVD and SACD. Whilst I gather there is huge support for the new Oppo I struggle to believe it would handle music as well as the Arcam. Also I would be resigning £1800 worth of perfect kit to a bargain basement price on e-bay. Thanks for the suggestion though - and when the time comes to change my kit I will definitely be looking at a universal player.
You could bite the bullet and buy a HD equiped pre pro and spend between 1400 and 2300ish. It means leaving Arcam. But Audiolab, Rotel, Marantz should be able to 'help' out. You'll end up having to do it anyway so it seems a bit pointless to buy a MCH switch for a short while and then ditch it.
Eg
Audiolab 8000AP, 8000x7 for 1400ish
Audiolab 8200AP, 8000x7 for 1850ish
Rotel 1570, Audiolab 8000x7 for 2050ish
Marantz AV7005 for 2350ish.
All will do HD audio (the Audiolabs are LPCM only though, which is all you need anyway for HD audio) with the bottom three allowing 3D and the bottom two coming with HD audio decoding on board and video processing. The Marantz being fully loaded with all the toys.
The Audiolab 8000x7 power amp can be had new for 650 at the moment so it's my power amp de jour. Though I bet you could get other decent makes second hand for 500ish.
Just a a general vent, ideally Arcam would sort themselves out and provide some lower cost alternatives but I refuse to spend 3500 on a piece of kit that is a bit short on the features list or worse still 2500 (a premium price for a receiver) that is pre-out less thus not expandable and will require a back to base refit to provide 3D capability.
I can give them a pass at lower price points but the current price points feel like they are taking the proverbial with the feature sets they offer and then adding insult to injury by not providing analogue MCH on the new bluray player or any indication of a SE version which would have been an upgrade path for existing Arcam owners, well frankly they can bugger off.
