I know the Beosystem 10 is viewed poorly by a number of members, and these views are echoed by Tim Jarman in his book and on 'Beocentral'. I feel I should defend the much maligned piece.
I've owned mine since buying it new in the very early 90s and it has performed as a portable radio and occasionally as a sort of tuner/amplifier in a small room with a BG 1700, a CDX and a pair of CX100s. It is very solid, still looks good after 20 years (mine is still mint, with its original box, handbook etc!) and has been used daily with absolutely no problems.
However, after seeing the optimistic listing on ebay recently, and referred to in another thread on this site, should someone want to offer me 995 GBP, I could be tempted!
