Bruce,
I totally agree with you concerning PL and the fun rolling tubes. I own the Dialogue Premium Int and it’s built like a tank and sounds great.
I tried a variety of tubes with this amp which I purchased from Upscale. I ordered it with KT120s but they were too harsh.The stock EL34s were better but a bit bright for my tastes.I also tried the GL KT88 which had a slightly better bass but again a bit bright. I decided on the GL KT77 which have a beautiful midrange and soundstage, good bass and not bright. Since I own stand mounted 2 way speakers, I added a JL Audio E110 sub to supplement the bass using the PL line output.
I called Upscale concerning different pre-amp tubes and they recommended NOS Cifte 12AU7 tubes based on my tastes. At first I replaced the 2 front tubes but I found it sounded even better when I replaced all 6 tubes. I also tried the Brimar and the Mullard CV4003 but they were also bright for my tastes.
Enjoy
