Any High End Tube Preamps with *gasp tone controls?

Transcendent Sound "The Fixer".  I believe it is zero gain. I know it is a kit, but there are folks on the Transcendent forum who would be happy to assemble the kit for you for a fee.

You will be shocked at the sound quality of the Transcendent amps and preamps.

Interesting ltmandella and much more affordable. It doesn’t mention if it has XLR or rca and they only put in a pic of the front of it. 

If you like affordable vintage, the SP3a1 is hard to beat.  Costs less than Mac preamps, and based on my experience with a 110Z and C20, easily outperforms them.  The ability to defeat the tone control when it isn't needed is a sonic bonus.

I’m with you! While not considered high-end, I still use an NAD 1300 Monitor Series preamp with 6 bands of eq available to shape sound. I use them regularly to optimize sound (to my ears) depending on the recording, as we know all recordings are not created equal.

I also tend to use eq differently for vinyl and digital in my system, usually defeating the eq for vinyl and adding some sparkle to digital in trying to replicate the vinyl sound.

As an older gentleman, I also find my hearing is changing and that I need a tone control, I have therefore incorporated a Schiit Lokuis 6 level tone control into my system. It is fully balanced in & out (RCA's are also there for my tube amps when in service). I find this is very useful when playing some older vinyl and poorly recorded items. The only drawback is that it doesn't have a remote like the Loki Max, but it was only about $500 which is reasonable (Price was $300.00 plus taxes, delivery and duty).

I have used it for about 3 years and find it invaluable in about 10% of those recordings between my hearing and the sound of the recording that requires some minor tweeks in my judgement. It has a tone control by-pass so flipping the toggle to "off" is all that is required for most listening. I find any alteration in sound quality with the unit installed is so small, given the benefit provided, as to be insignificant. This is just my experience, I would probably opt for the Loki Max today, just for the convenience of the remote.
