Hi Recently bought a Cambridge Azur 640A V2 CD player and what a difference to my current system. Took some time to run in, but since then, very happy with it. It has since rekindled my enjoyment of music and I'm starting to get the bug to improve the sound further. Present system comprises of Denon PMA-350 Amp Mission 763 floorstanding speakers Systemdek 2x900 turntable with Rega RB250 arm and Goldring 1012 m/magnet cartridge These are all 16 years old, due to the last upgrade I did. Cambridge Audio Azur 640C CD player I am thinking of upgrading the amp and speakers, but will obviously be using both source components. Probably use the turntable as much as the CD player as I have a large vinyl collection, so the new components will have to match this as well. I am wondering if the Cambridge Audio 640P pre amp would make a great difference to this turntable for it's price of £60? Looking to spend approx. £500-£600 in total for the amp and speakers, new or secondhand, not really fussed. Music I enjoy is mainly rock, and some pop, such as Queen, Free, Madonna, Dido. The room where the present system is located has a suspended timber floor with heavy curtains, which I think does cause some problems as the bass does sound muddled and does not feel quite deep enough. Any suggestions please?
