two Channel equalizer recommendations

I think the K&T will do the trick. I like what I’m reading about it. Plus it has to have XLR and I like the fact that I can use my own power cord. For that price may as well give it a shot. Thanks again for the suggestion. 

I would not recommend. Graphic equalizers are nothing more than glorified tone controls and just add distortion.  If EQ is truly needed (and it rarely is in 2 channel reproduction other than 250hz & lower where, in my opinion, its a requirement) look into parametric equalizers.  Think of it - an equalizer cannot do anything real unless it has a microphone so it can fist measure the room.  Once it measures the room, only then can an EQ curve actually compensate.

If you want fairly neutral check into the eq popular with mastering studios, as they are doing just this: slight changes to completed stereo mixes. The prices do go up. A great yet lesser known company to look at is Gyraf. They make a 'tilt' eq that you might find interesting.

Oh and a restored and racked Neumann 495 / OEv / PEv or similar from vintage disk cutting console could be awesome

Nike coined the best ad phrase of all time: Just Do It! In a world where ad campaigns change month to month this one was so good it was used everywhere for decades.

Don’t waste time talking, studying, planning, - Just Do It! The act itself is the reward. Just Do It! Kind of long though.

The slogan for EQ is even better: Don’t.

Dear @cerrot  :  ""  and just add distortion "", yes and a parametric eq. does it too and can works for the OP.

Klark Teknik is not " one of the same " eq., as a fact this made/design in England is unique and you can read here:

Its distortion levels are low and KT has the 370 model with even lower distortion levels.

Nothing is perfect always exist trade-offs. Your very good system is an example of those trade offs because you own really good analog rig that through the phono stage you own develops really high distortions but that kind of phono stage is what you like and its trade-offs goes/meet your audio/MUSIC priorities even that that analog signal goes digital in your very good electrostatic speakers. As I said nothing is perfect.
