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.


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.
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.
