    Just a heads-up to anyone who might run into the problem that I had, if you have a DAC directly connected to the ZA3, and you're hearing very audible distortion on some songs, you need to use a preamp in-between the DAC and ZA3.

    This is my 2nd experience with a passive 2 channel set up, so I wasn't aware this was a thing and could happen. Was getting pretty bad distortion (crackling/crunchiness) and thought it was either the new speakers or the ZA3, turns out it was the Cyan 2's hot output through XLR. Using the Midgard as a preamp fixed it completely.

    Yeah, that would work. Measure the FR out to 100khz or so to see the whole filter response.
