JD,
I changed the rectifiers and input tubes right off, knowing from my previous amp that I liked the 50's RCA 5U4G-ST's over the Rubys, and I can't recall the inputs...maybe bugle boys or cryoset 6N23Ps. This tube preference was corroborated by comparing these tubes in the Torii, but my previous SE34I+ was family sound-wise.
Then since I had bass issues with the Torii's introduction to my system/room, I started playing with OB3 and OC3 Voltage Regulators and some 5AR4/GZ34 pretty fast. More room treatment, speaker adjustments, and very specific EQ in computer were bigger solutions for this, but I am glad I got these other tubes because they helped at the time and also opened a lot of doors for tube exploration and discovery. Finally (with lots of tubes of all types in the cupboard) fine-tuned synergy with various tube combinations is a lot of fun for me.
The JJ 6AC7 in my system/room took a long time to show what they were really about and to me were worth the wait. I prefer cryoset ones, but the "raw" ones sound quite good in my setup too.
Unless you have some system room incompatibility, you will be hearing great sound from the start, but you will also be burning in the amp internals, so it may be that broken in tubes could possibly help you get what you like during the breakin. Easy enough to find out. I always do whatever I can to just love the sound, be it cable or tube rolling, speaker placement, or whatever. It is so easy to roll if you choose to.
Then there are the bass and treble knobs, and the bias and impedance switches. So on the other hand, the amp is voiced well and there may be some merit to burning everything in at once as you get to know the amp.
I don't know what your old amp was, but I think the Torii is so revealing that breakin does not suck, but it is a notable deal in serious listening mode. In my system, everything perceptibly matters, especially after 200-300 hours on the stock amp. So if you do roll, I think it is relevant to consider that the sound you get from the tubes you use will change some after the amp and/or tubes burn in fully, so a subtle like or dislike now may become a different thing in several months. And this becomes even more relevant after finding system/room synergy with cables and gear. At this point, my system synergy is so complete that it will sound great with any decent tube given the right combination.
I just go for the best I can toward my personal tastes and room. But I have been called a tweaker.
