I have 30 year old kit and finally my Mission Cyrus Amp has given up the ghost. Thinking of the Cambridge CX A 60 amp and Tannoy Revolution XT 6F or Q-Accoustics Concept 40 - but not keen on how the Concept 40's look. Room is 4m x 4m approx. Plan to buy the amp first and then audition speakers when I have the cash to go further. Question on the Amp- is it worth paying extra for the CX A 80?? Speakers- any other suggestions- maybe stand mounted??
