Which Schitt Audio Equalizer operates as a loudness switch for low level listening

If you always listen at low levels, have you considered turning up your subwoofers?

I have a Lokius. I bought it with the idea of equalizing old vinyl, but after upgrading my vinyl playback system, I didn’t feel that I needed it. I barely used it, but it seemed to work fine. Wasn’t noisy, etc.

I don’t like introducing another component and cable in the chain, but it’s supposed to have a true bypass. My preamp at the time had a tape/eq loop. 

I have the loki max and it works excellently. I love it.  Easily will work as a loudness control to increase the bass and treble.   3 presets, balanced and a remote.

With regards to your your other post... I listen at low volumes a lot.  My Zu Definitions IV are very dynamic at low volume.  They wake right up with no need to turn up the volume to hear the extreme frequencies.   Two 10" dual concentric cones with no crossover driven directly from the amp.  Powered sub helps with the low freqs at low volume.  Also, you don't need a low powered amp for these efficient speakers as I am currently using a high powered SS Levenson amp to successfully drive them.

I also have the Loki max and would not b without it. IMO it is much better than a loudness circuit. I have several amps and my Accuphase amp has loudness circuit. The loudness curve sounds terrible to me. In  my situation I need less bass since my speakers are closer to the rear wall than I would like. The Loki fixes it perfectly. 

I, too, have the Loki Max, and it will definitely do what you seem to be looking for.  It's an amazing product, from my perspective.

As a loudness control I would think the Loki Mini would be enough at $149.  Now if you need full spectrum EQ....
