Passive Monitor Controller- Take 2

Some time ago, I sold my Crane Song Avocet (which was awesome). I was doing less and less music work and more and more electronics, so it was time to simplify. I built a very simple completely passive monitor controller with just the bare minimum features. It was just for me, so it was not pretty but functional. It has a stepped attenuator, polarity, L& R mutes and Mono.
 

Monitor Controller by Esi - the MoCo.

Today I recieved my MoCo, a monitor controller from the German manufacturer Esi. It is passive and can handle two stereo sources and two pairs of monitors.

It sounds very neutral, and is extremely quiet. It also has L/R swap functionality, mute and mono. Two things to consider: it has no status lights whatsoever and the housing is made of sturdy plastic.
