Audio Research.  Used to be quite the synergistic match with ML for Thiels.  Pretty sure it will work well with your Revels.  Keep us posted.  Best....

Initm, thank you, understood. There are so many rabbit holes to go down in audio. As soon as you think you have your pre where you want, then you begin to question your source, or cables, or whatever. Therefore, I have a question for you: when you listen to music do you often find it difficult to turn off? If so, then you probably don’t need to change anything. If you don’t, then you must find the weakest link. I actually got lucky when I replaced my pre and found the sweet spot. Music is VERY difficult to turn off now. Not that I have a perfect system, but for now I’m feeling good about it.

I would look at the Shiit Freya has SE and XLR, can be passive, tube or solid state changeable on the fly to suit your flavour.
Has remote volume, 4 inputs, and has maybe the best volume pot ever, 128 positions microprocessor-controlled relay-stepped attenuator .
All for $699

And you can send it back if not happy.

Comes with some pretty good creds by the designer Mike Moffat who made Theta Audio what it was when it was on top.
