I may be late to the party, but I own a Holo Audio May KTE paired with the Holo Audio Serene, and in my system they’re staying put for the long haul.
The May is extremely detailed without ever sounding harsh, and it’s certainly not soft or dull. I’m feeding it via a Holo Audio Red over I²S, which is clearly its intended signal path, and the synergy is outstanding.
Previously, I ran a PS Audio DirectStream DAC fed by an Eversolo DMP-A6. While I genuinely enjoyed that combination, my current setup is clearly on another level and has become my reference.
