Equalizer in a Hi Fi system


Just curious to hear everyone’s opinions on using an equalizer in a high end hi fi system. Was at work tonight and killing time and came across a Schitt Loki max $1500 Equalizer with some very good reviews. What are some of the pros / Benefits and cons in using one. Just curious. BTW. I’m talking about a top of the line. Hi end equalizer. Mostly to calm some high frequencies and some bad recordings.

Have reached new heights of audiophilism with the aforementioned Alice In Chains album with Wes in big rig. For 6 K you should with decent hi fi gear be able to get this album, which is recessed cymbals and decreased bass kick and forward mids due to loudness wars/ studio compression, to sound great. It’s even greater than before with the use of tube output combined with use of gain and iron pad dials. Great great feature on Wes. You turn up the gain say 3 dbs to slightly overdrive the tubes then iron pad attenuates that extra output. The end result is more resolute saturated mids and better bass heft. Meaning not only does it sound better but you can back off a tad on bass gain, always a good thing with EQ in general. AND every new move you make can be directly instantly compared to your last setting with the stored presets. 
And more importantly, I can be EXTREMELY exacting with listening and instant A-B comparisons as I sit in my listening spot with my Bryston remote and go back and forth with tape loop monitor button, toggling between the sound of my source > DAC > preamp > amp (purest way possible, true true bypass I call it) versus source > DAC > preamp > EQ (active) > amp. Note that pressing ‘Bypass’ on the EQ, the circuitry in this nomenclature looks like this: source > DAC > preamp > EQ in bypass > amp. 
I have been an utter mad scientist for days now with this thing, but what I’m getting out of it is incredible.

I still though stand by my conclusion that CO PEQ-1 is a MORE MUSICAL sounding equalizer. Which, in the end, trumps detail/ resolution for me. 

@tlcocks  It has and is still more of an adventure than I would like. We just got another update and it is improving. A lot of it is my fault. My system, because of its dipole line source nature, is difficult to measure the way their system demands. At this time I am having great success using its crossover and EQ to correct the speakers manually with the room control section on bypass. The DACs and sonic character of the unit are first class. Streaming Qobuz with Volumia is faultless. I got an old Shure V15 V MR and put a Jico SAS/B stylus on it. The MM phono stage sounds great although it could use a couple of dB more gain. 

From my experience with digital signal processing and target curves since 1996 I know exactly what I want to see and hear. I use both my hearing and amplitude measurement to adjust the EQ. I could never get what I want to hear without it. 

I would love to hear what you’ve accomplished thus far. Also, if you ever come to know of someone in Florida doing what you’re doing with DEQX and can demo it then please let me know. I wish you the best of luck with your continued success with DEQX. 
I have had a great deal of fun exploring the various analog boxes. My curiosity over DSP remains strong though!
