Looking for Tube Pre Amp Advice


Without getting too deep into every bit of my equipment I’ll ask for thoughts and advice regarding tube pre-amps

I currently have Parasound Halo A51 Amp. I’m using 4 channels(bi-wired) to power my PBN M1!5 speakers. I currently have a Parasound JC2 BP pre amp. 
Denafrips Terminator DAC>Sonore Signature Rendue-SE>Morrow Series 6 cables (XLRs and speakers)

Id like to try a tube preamp and keep my current amp. I’m looking for a little more holographic sound stage. Everything currently sounds great just would like alittle more depth. 
was looking at a PrimaLuna EVO 400 (dedicated pre version). It has a theater bi-pass

Im aware this is a tough question and matching solid state to tubes makes it even more complex… I did see great reviews on the Prima Luna and that’s about my price point for this

Another recommendation here for Aric - I didn't have room for the 2-box Motherlode, so I got the Super 6SN7, and later sent it in to Aric for the additional upgrades, which he said should get to about 90% of the performance of the Motherlode. Haven't heard the Motherlode, but the upgraded Super 6SN7 is a big improvement over the stock version, and I liked the stock version about equally with the LTA MicroZOTL level 3, which I'm now selling. Aric himself is a pleasure to work with, too. 

Hi

I’m not using vinyl. Im 99% streaming Tidal and Qobuz. All cleaned via sfp fiber and ddc with Denafrips Terminator at the end 

EAR Yoshino 868PL but if your bdget can push out further the 912 Two Tube pre-amps that will go toe to toe with anything at any price and phono stages that will best most standalones.
