For my suggestions you would need to go used ... Musical Fidelity A308 or A32 or A3 integrated amps. When I moved up from a NAD C320BEE to a MF A3, it was like wow and I played cds all the time. Now I have Prima Luna tube amps in 2 of my systems and even with the 30 second warm-up feature, I warm-up for longer as the tubes sound less scratchy, if I wait.
