What will a preamp do for me?

Missing in the chain below is a preamp - I use the DAC to control volume.  This is my only source and will be for some time.  What could I gain by adding a preamp?

I have Thiel CS 2.3s driven by a BAT VK-55, sourced by PS Audio PW DAC, with bridge II, mostly tidal.  The DAC serves as a preamp in terms of volume control.  Mostly Audioquest cables, amp power cord is Cardas Clear m, all fed by PS Audio upc-200.

I am am hoping to improve the highs, which sometimes sound smeared, too much sibilance; would like more air and clarity.  Loud rock sounds flatter, less dynamic than I’d like.  I am not willing to give up the deep detailed and beautifully resonant mids.  Willing to spend up to $3000, used is ok.  Totally balanced is a must.  Not currently willing to entertain the idea of different speakers - my goal is to make the 2.3s sound as good as reasonably possible before moving on to other speakers.  It’s easy to find a really good preamp in this price range, so much so I am almost paralyzed by the choices.  Aesthetix , Ayre, ARC, several BAT, Parasound and more all have apparently excellent models in my price range.  Patience would put Atma-sphere and PS Audio within reach.  Which is best for my situation?  There’s no way to audition all of these, how could I avoid getting on a preamp merry-go-round?  Or should I spend my money elsewhere?

The actual answer is in the listening. No theory is going to replace actually LISTENING to whatever gizmo or notion you have hooked up. Sure you can argue theories all day.. But the answer is in only one place. YOUR EARS, listening to whatever.
I own several preamps. and regularly use more than one at the same time. So I can say I am ANTI-(add whatever fancies you). yeah they become ’tone controls’. Why would I care what somebody else calls it? the sound is all I care about. Right now I have my $40 used disc changer to my $7000 SACD player as DAC, to the Threshold FET10 line level, to the Conrad Johnson ACT2, to the Bryston BP-26 (which has the only XLR line out to the amp) SOUNDS great. I can leave off the Conrad Johnson and lose little, but it just has that last extra bit of greatness WITH it in.(probably second harmonics added)

I’m not convinced an active linestage does anything needed, but might create a sound that sounds more dynamic
Could only sound more dynamic if the passive was hobbled with a serious impedance mismatch. As an active line stage cannot in any way improve the dynamics of the source.

George, I did say "create a sound that sounds more dynamic" not that it technically is.  A little fatter bass often conveys increased dynamics.  Passives seem more constrained in " creating a sound" but I'm interested in auditioning the Benchmark unit to see what they achieved with the best passive components.

To the OP, I will chime in....." Loud rock sounds flatter, less dynamic than I’d like ". Loud rock is not Thiel territory, and, with a tube amp ? Not to sound crude, but you have it all wrong. I am also a convert to passive, as I no longer want to "color " my recordings or hear less " detail and information " from my recordings with an extra gain stage or 2 that I do not need. I am the happy owner of a Luminous Audio Axiom II Walker mod unit, and have never been more pleased with what I am hearing from my recordings. Elizabeth.....3 separate gain stages ( Threshold to CJ to Bryston ). Really ? Enjoy ! MrD.

elizabeth, are you running your source signal through three different linestage preamps daisy chained and at the same time or I’m reading it wrong? Highly unusual setup.

Yes, I'm curious too, 3 preamps in series???
