I have an old Quad 44/405. The 44 needs repair, the 405 needs a service urgently. I have a pair of Monitor Audio Bronze BX2s and an Arcam cd73. I haven't been able to listen to music for nearly 2 years. Do I have Quads fixed/upgraded? What would a similar modern amp be and what cost, £3, 5, 700? What amp wouldn't be worth buying for use with BX2s eg Naims, Cyrus, Roksan. I listen to a wide range of music, Billy Cobham style Jazz, progressive rock Floyd, Genesis, Rush, Yes etc, classical, solo voices. I don't listen at loud levels but I want to be able to close my eyes and experience a precise 3D sound stage. For now it is the amp that needs attention.
