Not familiar with your wires either, but as interconnects and cables can make a significant contribution to what level of tonal color is revealed I'd probably start there too. I'd demo a full loom Acoustic Zen as I know them to be very organic sounding without sacrificing things like detail and soundstaging that seem to be important to you. If that doesn't work I might try to audition a good preamp. Not sure how the Bricasti does as a pre, but some systems seem to benefit significantly by using a standalone preamplifier. If you're not tube averse maybe a VAC or ARC pre, and solid state maybe Pass Labs, Boulder, Vitus, Sim Audio. Hope this helps, and best of luck.
Speakers or Amplifier
Thinking about another upgrade and looking for opinions on if I should upgrade my speakers or amplifier. My current system: Aerial 7T speakers, Jeff Rowland M525, Bricasti M1 DAC connected straight into the M525, and all WireWorld Silver inter-connect, power, and speaker cables. My room is 20' x 26' and treated with GIK acoustics. I listen to contemporary Jazz. My budget is 10K.
