Listening to Jay-Z's Kingdom Come and then Roger Norrington conducting Beethoven's 9th last night, I was struck by that perennial, nagging thought ; how can I improve my system to make the most of these and other recordings? Though both discs are somewhat distinctive musically,they both sounded hemmed in and less than euphoric. What next? Any suggestions out there on what might be a good upgrade route? Current set-up: Arcam CD92 Chord 64 DAC B&W 1NTs Arcam A85/P90 NAD 533 turntable Chord Signature interconnect (DAC to Amp), Van Den Hul The Second (P90 to A85), various Merlins elsewhere, QED 350 speaker cable(bi-wired). Some discs sound great, others not so. Help!!
