danezro: I’ve been reading up on this since my post and I’m not sure if this is an option or not. Can one buy a later Beomaster, such as the 6500 which I think supports Beolab’s as well as the latest remotes, connected with all the other elements of the 5000 system?
Basically yes (except for the Beogram, which would need an external RIAA preamp), but note that they will not look the same even if all are alu coloured. 5000/5500 are brushed aluminum, whereas 6500/7000 are polished. Personally having to watch such a mixup would drive me nuts.
But I agree that at £150 it would be worth getting for a completely separate setup! You'd still need to get some speakers, though...
