I have recently purchased a Naim CD5x and was wondering what would be the next move. The player is great with an almost analogue sound on some discs but i would like to explore its potential. I know its responds very well to the the Flatcap 2x but im also aware that its designed to work with the better amps. The problem there is whether to go the integrated route ( nait xs) or the pre-power route (122x and 150x). I have heard that the synergy with the nait xs is extraordinary. Any thoughts? Also im aware that my viennas dont suit the naim electronics prefectly. Would this route bring more gains. Any thoughts would be appreciated.
