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.

I bought an mx110z, one of the best purchases ever made. Extremely versatile old-school, balance, tones, optional low volume 'loudness', 

Terrific sound, great tuner, great sounding Phono, two phono, ...

this helped me decide

McIntosh Mode switch is a great help when balancing your speakers, setting anti-skate, playing mono lps thru only 1 speaker ...

If mine died, I would replace it without even loooking at anything else.

I use SUT for MC cartridge to keep using mx110z's phono!

IF you want to keep an existing preamp or integrated amp, lacking some features, this Chase RLC-1 provides remote volume, remote balance, remote treble and bass, so you make all adjustments from your listening position.

It’s S/N is 120db, no one can tell if it is in or out of my system.

None on eBay now, this one was sold but it shows it well

It also has built-in fletcher musnon ’loudness’ for bass boost at low volumes, only engages at low volumes.
I use a McIntosh C2500 tube preamp with tone controls, love it.  
I have a Luxman  CL-35 III. These were manufactured in about 1975. They sound good, but not as good as the CL-38. Additionally the CL-38 has built in SUT and a remote control.

Try using to search for it.
The  Schiit Loki is an add on which costs $149. I have never heard it and am in no way associated with it. But It may be a less expensive alternative. Another alternative MAY be  a subwoofer. However that depends on your speakers . IE, my speakers have very good mids and highs but lack bass. Generally I set the subs and forget them. But every now and then I just need to tweak the lows or highs. Too much bass kills the highs. Too little bass takes away the punch. But again, my system is at a good place where it works for me. Not sure it is for everyone, especially if you are fighting too much bass as it is.
