PrimaLuna Preamp Upgrade Question


I have owned a PL Evo400 Integrated for the past few months. I love the amp, but am considering diving deeper into separates. I've been eyeing a Primaluna Evo Preamp to hopefully unlock more separation and presence.

I'm curious if anyone has any experience with owning a Primaluna Integrated and then adding a Primaluna Pre Amp using the HT bypass. I understand this is a possibility, but I'm curious of the added benefits and or drawbacks. Is there is a general consensus it would be greatly beneficial, I would eventually sell off the Evo 400 integrated and go full separates. 

If you don't have specific experience with PrimaLuna but have been in a similar situation using a bypass in an integrated I'd also love to hear some feedback.

+1 for @tablejockey  comments.

only additional comment is you have not heard what the PL Dialogue P can do until you replace the coupling caps with copper foil caps. then you jaw will hit the floor....
Pulled the trigger on 6 12au7's, which ill start with the driver tubes and then the flanking tubes. I also skipped over the KT88's and went with Tung Sol KT120's. Should have them early next week and excited to experiment and compare. 
Add me to the list of "tubes before separates". I own the EVO300 and swapped all tubes: power is GL KT88s and preamp tubes are a combo of NOS Radiotechnique and NOS Telefunken. The upgrades to the tubes made a sizable difference, enough to satisfy my ears and not think about any other changes. 

There is a good thread here about integrated vs. separates and although many agree separates have benefits (less cross talk, interference, etc.), PL does build their integrated quite well, and my philosophy has been to look for improvements elsewhere. To my surprise, one of the biggest benefits to date has been a good linear PS for my DAC!

Happy trails!
I have a PrimaLuna Dialogue Integrated paired with the Aria 936s’s. I too found myself in the same mindset of upgrading within a year of the new system but never really considered separates. I chose to upgraded the system by adding two subs, high-end replacing all cables, power cords, and the power conditioner. All replacements purchased in the used market (except the subs). Most impressive and surprising was the SR Powercell 12 UEF power conditioner. It was my second addition to the system after SR power cord for the integrated amp and I was taken aback with the improvement! In fact, I was underwhelmed at first, though, after bout 15 -20 hours of listening, I was dumbfounded. It was remarkable! Without getting into a bunch of adjectives, I basically now have a different system as far as soundstage and clarity compared my original system less the upgrades.

Now if I ever replace my Primaluna, I doubt I’ll consider replacing cables, power cords, and conditioner.
There is a school of thought that, assuming you will included high-end cabling and power cords, separates require purchases additional sets of cables and power cords. Everyone’s budget is different but certainly, something to at least consider.

I too must echo that speaker placement is paramount.

Cheers and good luck with your journey!

Edit:  I forgot to mention that I rolled some tubes as well.
