hey guys currently got cambridge audio 840c cd player, cambridge audio 640R AV amp with tannoy r2 speakers. I heard the cd & amp in the shop sounded really good but sounding thin & lacking bass with the tannoy R2 speakers. Am thinking of upgrading the speakers to the B&W 684 speakers, Any advice guy. Oh cables interconnect Van den hul the wave. Speaker cables 8VS kimber cables. thanx
