I’m not sure if this belongs in this thread, or the [ZMF Atrium](https://forum.headphones.com/t/zmf-atrium/17438) one, but at this point I would have to say that, for overall enjoyment and engagement, my overall favorite solid-state headphone listening setup to date is the Zähl HM1 (in simple Class-A mode) feeding the ZMF Atrium.
