I think you have captured my experience, though I am not using a preamp or aftermarket DAC. Being as your testing the Amethyst, should I assume your not using the Pre/amp discussed earlier? With that, where in the chain are you placing the Trinnov?

One of the things that I liked about the Trinnov is the ability to make your own "Trifield". So with a bit of skill, you can use LRC on stereo audio. Not sure if your test environment has the capacity or the desire, but its something to consider as well.

Looking forward to round two of your review.

Primary: MD600, MS200 (SpeakerLink to AES), Trinnov ST-2, Ayre V6-xe, Salk SS8 3x LRC.
Secondary: MC600 (whole house).
Zone one: 568.2, G57, MS200, Spatial Hologram M2SE.
Zone 2-6 (Awaiting assignment).
