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

The OP was talking about LP playback. Many of you recommended DSP. That means digitizing the LP playback in order to manipulate the signal digitally.  Why would you do that? Use a digital source if you want to use DSP. Use analog tone controls or an equalizer if you are starting from an analog source. If you like the sound you get then don’t let others tell you it’s a bad thing. Try the Schiit. You can return it if you don’t like it.
I use a soundcraftsman octave equalizer in my system. It is 80's analog, but it gives me the ability to adjust, albeit imperfectly, for a given recording/signal source. Cassettes tend to be a little weak in the high-end, while some vinyl is overly heavy in the low-end. Having an equalizer allows one to smooth out the frequency that is heavy or light. The best way to think of it is it makes you the recording engineer and allows you to adjust the material playback. 
How you adjust it is entirely up to you and your ears. 
I change out speakers and gear constantly. Marantz 4270, emotiva pt-100, adcom gfa-555, Onkyo m-508, magnepan 10.1qr, Dahlquist dq-8’s, Klipsch rf-35’s, JBL 4312’s, and my Rusty but trusty Denon dp-1800 turntable. I for some reason adhered to your same naive tone control mentality for most of my life. But a year ago I got the Schiit Loki. I’ve had several pretty lights equalizers over the years. Always thought they added more noise than was worth. But having the Loki I absolutely think it’s an essential piece of gear in my system. It sounds fantastic. No audible noise floor change. It sounds better than my marantz tone controls. And I love being able to tame a harsh recording or speaker with ease.
kphasap,

When using the Loki, do you keep the tone controls on your Marantz defeated (off)?

It wouldn't be advisible to use The Loki and the tone controls from the Marantz at the same, correct? 

Thanks
