Preamp under $2,000 used

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.

4hannons, Thanks for response, yes I do have a hard time turning off, some things sound amazing, its broadening my listening scope of music. Cables are pretty good, Kimber speaker cables and Audioquest Columbia RCA. Yes you are correct you can also rethink or read reviews on different components and cabling and wonder, I think some things may be irrelevant once you get to a certain level of good components/ cables just a matter of opinion.

Thanks to all for feedback, Conrad Johnson sounds like a great option and a few others. I was really hoping for more feedback on Levinson since my amp is Levinson and Ayre or Parasound- solid state type preamp. Although this has perked my interest on some tubes suggestions. 
Oh and if anyone has not tried Tidal HiDef it's pretty amazing. 
Thanks! 

Initm, I’ve never owned Conrad Johnson, but heard it recently at a dealer...very rich and full sounding, but a bit too soft, I like a punchier sound with dynamics and detail. Music should be fun to listen! I currently own tube and ss pre’s. I don’t notice ss is any quieter than tube, if that’s a concern. Getting advice here on Agon is great, but only takes you so far, at some point you just have to jump in the pool. Please keep us posted on your interesting journey.
