Tube Pre amp with tone control suggestions


Hello all. 
I am considering going to a preamp with tone controls. I know its not the purist point of view but wth it's all about what I like to hear. I have an Audio Note M6 with Phono right now, considered pretty good but I miss tweaking that bass or treble on certain recordings. My solid state gear gives me that ability and I like it.
My thoughts are a few Mac's like the C20 or C22 or the MX110.

How about up to $5k on the used market and it doesn't have to have Phono.
Thanks in advance for any suggestions.

All excellent suggestions. I have several Subs I have put in and out. Don't really want to go to sub route. I have a good sub and it definitely does add to it
, I have various speakers that I can use cornwall's tannoy mg12 a few others. I know none of these speakers lack the bass when being put to them. I will look into that $149 option.
The Schiit Loki is an excellent EQ, but can only be used in a single-ended setup. It is the most transparent analogue EQ I've ever heard. 


Interesting. My amps are single ended, Audio Note P4 mono block's, but I am not sure about the pre amp
As a couple of others have already, I'll also throw in my recommendation for the Luxman CL-38. I bought the standard version a few years ago and liked it so much I bought the SE version. Both models sound beautiful in my systems, and are well within your price range on the used market. The great thing about Luxman's approach is you can select the shelf frequency for both high and low, and the boost/cut isn't 'out of control'; it's tastefully done. And when you don't need the tone control, simply hit the defeat switch and the circuit is removed, given clean straight-through line signal.
