Question about Tone Controls + Equalizers


So I wanted to get opinions on Tone Controls.

I listen to all my music including LP's with Tone Controls defeated.

Why do I do that, you say? Because when I started on this journey I had the impression in my mind that in order to be an Audiophile, you have to listen to all music in it's purest form otherwise you are degrading the sound (I know, a very novice and naive mentality). 

So my first questions, do you all listen to LP's with tone controls on or off (if you have the capability in your system)?

My second question is about equalizers and in particular the Schiit Loki. If you have Tone Controls in your system, is adding a equalizer or tone control system useless or does it interfere whit your built in Tone Controls? Would you have defeat the Tone Controls on your own system in order to use the Loki or could they work with each other? I am not sure.

Do you all think a device like the Loki could possibly help fine tune your system sound? Is anyone using it in their own rig with LP playback?

That is what I would use it for, LP Playback, if I ever got the Loki or anything similar.

Thanks

I use the Loki when a recording needs some help, otherwise it's out of the system but ready to be hooked up when needed. I've used all sorts of EQs in pro audio and recording over decades, prefer the "purist" approach in hifi with no additional eq, digital or otherwise, but that Loki is an amazing thing when called on....great product.
I don't use tone controls with vinyl playback.  My pre-amp does have tone controls but i don't use them.  I do use the digital equalizer in iTunes for a very few early digital recordings.   
Thanks everyone for their inputs and suggestions.

Always looking to learn about how a system can be improved even though we may not all agree on the approach we can still learning something new, at least I do.
My "Tone Controls" consist of adjustable vertical blinds in front of the 12" windows behind my speakers for the high end and mids, plus removing the grills.  For the bass, I use a separate, but matched amp and preamp for subs, with a double pole double toggle to switch or remove bass crossovers, for the purpose of keeping things in phase while having the ability to add harmonics for old, crappy recordings, especially on LP.  Yes, I did measure the center of the main and sub magnets to place every thing in the same plane.  If you have an extra amp and preamp, give it a try on subs..
LOKI works great for me. I use it most of the time because in my living room my speakers have too much bass despite positioning adjustments and bass traps. So I tame the bass a bit more on many recordings with the LOKI.
its easy to defeat During use,  and doesn’t add any noise to the signal as far as I can hear.
If i were you I would defeat the tone control on the amp if I had the Loki in the system.
Simply a bargain. Check out the Audiophiliac review on YouTube for Steve G review.
