Ok, you lot have a lot of explaining to do to my wallet!
So far I have....
LISST's
The "Made in Canada" stock tubes that came with the Lyr2.
On order I have
1974 Matched pair of Voskod Grey Shield 6N23P's
Matched pair of Dario Miniwatt Gold pins, Date codes F8J2 & F9A3
Is there any other tube to get that will be ground breaking without killing my wallet?
I would recommend that you listen to the ones you have so far. You have a nice set to start. Decide what you like and do not. Then read more of the posts to determine if any other tubes share the traits you enjoy.
The Dutch boys would tell you to pick up some made in Heerlen Holland Amprex E88CC. The Telefunken and Seimens are great too.
It will come to personal preference.
Enjoy your growing collection...
