Thanks for all replies. Gave me a lot to think about. After much (and I mean much) consideration and brain bending deliberation with significant other I have decided to ditch it all and start from scratch.
Yesterday the drawer on my TEAC VRDS10 refused to open again (motor runs but tray needs pulling out). This together with crackles and drop outs on the Cyrus 2 pots (requiring application of switch cleaner and frantic twiddling of input dial for temp cure) pushed me towards retiring the old set up rather than fixing. It has provided 21 years of almost daily service. And I mean it has had a hell of a lot of use. So, soon I shall be sticking them back in their original boxes and I'll decide what to do with them later. But I'm looking for a complete change, so have pretty much decided to keep only the cabling.
After looking at all the opinions on dedicated vs combined set ups I'm going for combined. It has to be the way forward for me. 'We' want the space freed in our small front room really (and SO insisted on this and she is actually right on this one and I agree). So pretty much set on getting a Cambridge Audio Azur 751R and Azur 752BD combo and later perhaps - after establising what the 752BD can and can't do - get a CA Stream Magic 6 and a NAS server and rip all my CDs to FLAC. So, really going for a complete change!
Still haven't decided on a speaker package yet, but the fronts have to be good for every type of music but particuarly for acoustic and vocal stuff, but not has aggressive in the high frequencies as as the 751s . To be honest, I've always found my set up to be a little on the bright side...but 21 years later it's a bit late to whine about it. Also, have always felt the absence of the lower frequencies; the 751s can't deliver in that respect....well no smaller speaker can really. But I'm not after deep bone rattling bass in any way (really don't want it at all in fact), because one, I don't enjoy my innards being pummeled, and two, I do have neighbours and I'm a nice fella and don't want to piss them off; nothing worse than putting up with someone else's bass relentlessly booming through the walls! That said, I'd like something that goes down a little deeper than the Missions are able to and something that doesn't audibly bottom out and 'flubb' the notes when they can't deliver like the M751s do.
I do like the surround experience, and I clearly don't want to ignore it, hence the CA AVR, but after spending the bulk of my budget on the Cambridge audio stuff I have to consider the cost of the speakers and the size. SO wants small, unobtrusive surrounds and centre etc. but I won't have a dinky front pair. I have to say, in a small room speakers hanging off of every wall is a bit too much, I get that, but the fronts are for my stereo music so...
Anyhow, if anyone can suggest speakers I'd be much appreciative. Forget the Missions as a guide for taste. The setup was always a compromise really. I started out listening to music through BBC valve amps so I like a slightly warmer sound really, but without the loss of detail.
Cheers.
