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

The Supratek Cabernet DHT is truly a wonderful pre amp, have been using it now for some years and hope for it to be my end game pre.

For sure there are a lot of happy Supratek owners in the world and I believe it once was one of the biggest threads on this forum

Unfortunately Michael Maloney has some health issues and I am not sure if he has any pre amps left for sale.

Wow gentlemen's, you have all given me a lot to sift through. All wonderful advice and I will start my research looking to see what options you’ve all suggested pairs the best with my Parasound SS Amp. 
I think I’ve come to realize that this pre amp selection is an important one to say the least.  I will report back once I’ve made a choice, purchase, and opportunity to give proper feedback!!

Your amp I believe is fully balanced and believe it may sound best that way, which is why I didn’t mention the LTA MicroZOTL, so you may want to consider a fully-balanced preamp in your search criteria.  FWIW, and happy hunting!

There are a lot of great suggestions here. I will definitely agree with the Aric Audio Motherlode II. The XL is the balanced version. IMHO, this is my endgame preamp. Aric builds some wonderful pieces. 

Bobby: I have the PrimaLuna Evo 400, I wanted it for the balanced connections option.  I’ve used it with a few different amps, but currently use it with an Aesthetix Atlas hybrid amp.  In a word….BLISS!  You can pick these up on the used market for roughly $4k, it’s a beautiful unit, incredibly well built, very heavy and well deserving of the accolades in my opinion.  Don’t let folks dissuade you that it’s Chinese, only the labor to assemble is Chinese as all the parts are first rate materials and the lower cost labor keeps the price down.  My speakers are the Vandersteens Treo CT’s and I’ve had numerous folks from our audiophile club by and rave that it’s one of the best they’ve heard.  Give that PL Evo 400 a shot, I think you’ll love it!
