I have a prologue 2 that I Love. I tried many combo's with this little integrated. I know everyone's system is different but man did I hit it. I am using gold lion 12ax7's rt 12au7's and gold lion kt-88's. dh lab cables and a virtue audio piano m1 player (sleeper awesome player). man at first I put the gold lion's in with some mullard 4003's to much warmth and I had a pair of 1965 rt 12au7/6189's from uncle kevy @ upscale and it opened up the sound stage very nice. Very happy. I also tried a pair of mazda/cifte 12au7's that were nice also but I liked the rt a smidgen better. very cool....Btw The biggest upgrade I have ever done with this amp is change out the caps and put in audience auracaps holy shit!!! open it up everything got MUCH better and refined....

Have you tried v-caps yet? They are very impressive, but large and difficult to locate if the real estate is limited. Jallen

I had a power tube blow 2x ( 3rd owner and JJEL34B tubes :( so Kevin suggested sending it to Mitch in LA. I had him replace the caps with Hovland Musicaps since he had it there and it opened opened up the sound and seemed smoother after they broke in.
I use EL34 with RCA Cleartops and Tungsram 12ax7. I tried the GL 12ax but too dark for my tastes. I did use them in a 15wt EL84 amp and they sound great there lol
but at a price.
To infinity and beyond!!!
yes there is, I was first looking at Jensen copper & oil but to much $. I had to consider 2 things I had a budget and room inside the amp on the autobias board. The auri caps made a Hugh difference. more air sound stage tighter bass detail separation inner detail just everything was A LOT better. The change was very dramatic compared to the stock solens.
You should have used the Russian K40y-9s or the Russian kbg's...These are military grade caps that are sold for a fraction of their actual value being surplus not to mention they aren't metallized and are hermetically sealed..The larger auricaps don't sound too bad although I don't care for stranded leads going into a cap due to separation and moisture over time..They do have some paper in oil like qualities tho in their sonic nature which is a good thing.
When problems become increasingly difficult,we can always rely on our collective knowledge and seek relief.
What caps did you replace with Auricaps? The two coupling caps?
Vinyl + Tubes= Bliss
the 2 coupling caps and the 4 on the auto bias board
