Really loving the Conductor 3X Reference after installing the 2 classic opamps with the vivids. This takes away the ess DAC treble glare and gives it lush and body in the mids and bass. Super smooth now with the Susvaras!

Other than the opamps giving me issues in the I/V stage with static noise, switching it to LP is fine for the time being until I get that figured out.
