What to add next? I just bought the Cary to replace a NAD 515 carousel and was a bit disappointed in that the change didn't overwhelm me. I am thinking of changing the interconnect, but to what? Listen to mostly jazz, classical and opera.
I just took a look at the Unison Research Unico, man what a sweet piece! Pure triode input stage mated to a MOSFET output, I'd love to try one out. Looks great too.
As Marakanetz suggests, cables may be the reason, but I think the culprit could be the NAD amp. The Cary is a fine player and would probably benefit from a better amp downstream.
You listen to classical, opera and jazz. At high volumes or moderate listening levels? How would you characterize the sound of your system and what improvements were you hoping for?
The Klipsch KG4s are classics, they might benefit from an integrated like the YBA Integre, Audio Refinement Complete or Electrocompaniet ECI-3.
