Hi Scott, when you say you are using a schiit eq I'm assuming you run the analog outs of your CD into the Technics. Instead of that, you could replace it with an ifi itube2 or some other tube buffer made by Decware or Fosgate?
My bought new itube2 has been in service 24/7 for a little over 5 years now. Highly recommended but you might have to buy used. I paid $375 and one of my best buys for musicality yet still highly resolving that songs or dialogue on TV, words were much more coherent but only use in unity gain otherwise the upper mids slightly harden (no sibilance, just a sense of hardening). Highs and cymbals still so natural no hint of fatigue and I wouldn't say mids & upper bass was warmish, but body of instruments fully fleshed out.
Alternatively, have you tried using the CD coax out into the coax input on the Technics, thereby using the Technics' DAC. You could then experiment with different Coax cables which *DO NOT* present music or sound the same. I use an active powered Acoustic Revive, the best depth and layering I've experienced in digital but they are hard to find these days. It was revelatory compared to Silnote, Hi-Fidelity Cables Reveal, and others I can't recall now.
Even as audiotroy says your Cantons can be bright, you might be able to flesh out more musical body out of them. Best of luck!
