Just an update and a thank for all the helpful advice.Having got the speakers positioned right and found what seems to be an ideal cdp(Kenwood 8020) I am now a very happy bunny and can't see me wanting to change anything until something breaks(which seems unlikely).
The offshoot of my search for hifi has led to my son having a very enjoyable rig of a Cambridge cd4se/Rotel 820/MS20i pearls which play his current marshall amp driven tunes very nicely.
Thanks again
Steve
