Aside from the already peculiar wide range of non-substitute but acceptable output tube and voltage regulation alternatives in the Mini-Torii, don't you guys find it curious that it can also take as wide a range of input tubes as 6N1P, 12AU7, 12AT7, 12AX7 and even manages different spec rectifiers at the same time (i.e.,, EZ81, EZ80), when absolutely all such alternatives are definitely deemed as not substitutes in the valve literature? Amazing! I wonder what are the (if any) trade-offs involved.
Sounds like a cliché, but this really implies having the possibility to change your amp according to your mood, room conds, cables, ancillary equipment changes, etc.
The only constant here is the low-power/high sensitivity speakers' scheme. Everything else is modifiable. In fact, I bet the ZStage (great concept!) can even further enhance the already incredible family of possible scenarios in a truly significant way ... A true trigger for tube-holism and an endless source of creative interest!
And the music, Oh! the music ... such sounds. All of the above would not mean anything if the end result wasn't the enhanced enjoyment we all share from our music. Err.. you can tell I've been without my amp for long enough now
