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.
