Brrgrr, So far, I havent heard an amplifier that couldnt be improved by upgrading the stock tubes. So, that might be enough for you; it frequently was for me - at least until I found and could afford a clearly superior amplifier. As a rule, I consider it highly advisable to seek out the right tube set for any amplifier.
Tube rolling can be chancy, expensive and frustrating; all of which become worthwhile once you find the right set. I tend to think of the manufacturer supplied tubes as a sort of blind date chosen for consensus appeal. I appreciate the effort, but only I am listening to my music with my system in my room.
