Befaco Stmix 4-Channel Stereo Mixer v Erica Synths Black Stereo Mixer V3

Befaco Stmix 4-Channel Stereo Mixer Module v Erica Synths Black Stereo Mixer V3
Any thoughts on these two mixers?

Befaco Stmix look good and has good functionality - I heard the Erica Synths Black Stereo Mixer V3 is very quiet,

Has anyone tested them - know what the befaco is like noise-wise?

Not heard any noise. It's just the usual op amps in a mixer with only 1:1 amplification so would take some serious bad design choices to make it noisy.
Nice module. Using left input only gives you mono. Aux in is handy.

I use both mixers. They are excellent (and no noise problems on the StMix!).
My most frequent configuration: StMix and/or A-138s as sub-mixers (either of which can end up on a stereo effect: reverb, Data Bender, etc.), and the Black Stereo Mixer V3 as the final mixer before the Listen IO output module.
Some details differ (see the manuals) like a 5th input on the Befaco or the merge of mono channels on the Erica Synths.
The choice will depend on the context of use.

thanks - appreciated :)
