Primaluna tube gear

I owned a PrimaLuna ProLogue One for a time. The unit was heavy and sturdy, but sounded, well, heavy and sturdy. Granted, the ProLogue One was the cheapest in the lineup, but I had a Sophia Electric Baby amplifier that was a far better sounding amplifier and cost about a 3rd of the price. My 2 cents anyways.

Bought a Primaluna PL2 5 years ago. Upgraded the rest of my system several times sill have the Primaluna.

I am running a Primaluna Prologue Three preamp feeding a Prologue Five amp.
I found the stock Chinese tubes to be lacking.
In the Prologue Three I replaced the rectifier tubes with early 60's Mullard 5AR4's, the driver tubes with NOS 60's German RFT/Philips 12AU7's, the input tubes with 60's Telefunken ribbed plate 12AX7's.
In the Prologue Five I replaced the Output tubes with a new quad of reissue GL KT-88's, the driver tubes with late 50's Sylvania long black plate 12BH7A's and the input tubes with new Black Sable Cryo treated Sovtek 12AX7LPS's.
My tube rolling has really made these Primalunas sound wonderful. They are not leaving anytime soon.

The inspiration for my recent foray into tube hifi (plenty of tube guitar amp experience prior to this obsession) was partly inspired by hearing a Primaluna integrated a friend was raving about and a VTL I liked. Consequently I bought neither and instead bought a new Jolida JD502P amp with the "factory" upgrade mods, and stuck KT120s in it. It's inexpensive, sounds beautiful (I use a SS pre), and the "ez bias" works perfectly. There are zero "official" reviews of the thing and no advertising. Amazing. I think the Primalunas are beautifully made, but based on my informal comparison of a at least a few tube amps, I think this Jolida is a giant killer, so to speak.
