Currently running: 2 NAD 2400 thx amps, NAD C165BEE preamp, Emotiva DAC, Klipsch Chorus I's and JBL L60ts for my music system. The system is strong, warm, but seems a little dull and lacks detail. I was thinking an amp upgrade might unlock or wake up the system. I am considering maybe the Emotiva Basx A4 power amp, inexpensive and the SPECS look good. Is it reasonable to expect the new amp to sound better than 30 yr old amps? I appreciate any suggestions or comments.
