I currently have a Marantz CD-17 Mark 2 KI Special Edition CD player, which I have had from new in 2001 and have been very pleased with. The rest of my system is; - Arcam A85 amp & Arcam P85 power amp (bi-amped) - Monitor Audio Silver 8i speakers - High quality inerconnects and speaker cables - Denon TU-1800DAB tuner I have always hankered after trying a Naim CD player, as they are stated to have a very dynamic, rhythmical, natural musical sound. I am currently looking at a mint second-hand Naim CD5X on Ebay. Do you think the Naim CD5x will be better than the Marantz? Have had conflicting views from friends. Have not yet found a Naim CD5x nearby that I can A-B directly with my Marantz. Any views guys?
