I have a Rotel RA-05 amp with a Marantz CD6002 cd player and B & W 685 speakers on Z2 stands. Cables are QED silver anniversary with a val den hul the name interconnect. I have got the upgrade bug and having read the mags it seems that a Roksan K2, Cyrus CD6se and ATC SM11's would be good to go. Assuming that i like the sound of this kit, what order would you recommend upgrading as i can only replace one piece at a time. Is any of my kit able to stand being paired up with better replacements?
