Hi, I have a pair of Kef Q30's and an old Marantz PM47 amp that I have not used for a while due to various moves and the demise of my Marantz CD46. Basically I want some opinion on whether I should upgrade this current system. Maybe get a new CD player like the Marantz CD6002 now, and at some point in the future look at updating my amp to a Rotel or Marantz model. Or should I maybe head to Richer Sounds where I can get a Marantz CD5001 and PM4001 system for £150 and maybe also treat myself to the MS Avant 902is (£100) or MA BR2s(£150s - Sevenoaks). That's a whole new system for £250 to £300. I'm really not sure how my >10 year old Kefs stand up to modern bookshelf speakers. I just want a system where I can hear a good separation of the instruments and a natural sounding frequency range. I listen to classical music, a little electronic music and acoustic stuff too. Thanks.
