How can I go about using an eq on my Dali MS 4.

 What are you using for speaker cables ?  Owned those speakers in the past and found them very responsive to cable choice. 

Some modern amps don’t easily allow the insertion of EQ into the signal path.  So please share with us what amp you use, and also what your comfort level is with computer technology, because DSP based room/eq is a thing that might help…or terrify…you.  The Schiit Lokius is what I use, and it is super simple if your gear has the right connectivity.  McIntosh has some models with similar facilities built in.

I’m using a McIntosh MQ112 Environmental Equalizer.

i only use it for old song touch up, not for room EQ. It’s very clean and trust the quality. It has a bypass switch, and usually run it like that, unless some songs need touch up.

Been using the brilliant Schiit Loki Max for a few years and it works perfectly. I  rarely need it but when I do, it works. Remotely.

Add in the Charter Oak Peq-1. No noise, completely transparent. You’ll keep it a long long time. Amazing pro finishing device. Really useful for music you love with less than optimal recording parameters. Find it used if even possible.
