I am new to the world of separates and have just bought the cd5001/pm4001combo at RS. At present I am using bi-wired gale monitor gold speakers (using basic QED cable) in a room 3m x4m. It is certainly an improvement on my old Teac CR L600, which will now be consigned to the bedroom. My first question is this: would a change of speaker to a WHFISV 5 star pair e.g.Tannoy Mercury F1 custom, Wharfedale 9.0/9.1,Mordaunt Short 902i, Monitor Audio Gold BR2 (budget £150) be a noticeable upgrade as I was thinking of getting Tangent Evos for the bedroom? If the upgrade would be worthwhile which would be good for 70s Folk (Joni Mitchell, Cat Stevens etc) Jazz and some choral classical? I have read on the forum that a subwoofer could be added to the amp for classical. If so what would be good and (excuse me for being technically limited) where exactly to the red and black sub woofer wires go in the back of the amp? I would like to run a second set of speakers to the kitchen. Would this have to be sacrificed for the subwoofer? Any help gratefully received.
