PrimaLuna ProLogue One versus Two

Question for Kevin Deal:

Since the 12AX7 has "a more important role" sonically, does that mean it does the voltage amplification? I'm confused because at first you said 12AU7 is the driver tube....

Perhaps you could describe the different stages of this amp a bit.
Thanks

Kevin
With all the respect,I had a crack when read your comment on the "cheap-o-stuff".What should we call the Primaluna?
Made in the People's republic of China.What about the cheesy name?LOL.
All the best

Dont look now, but some of the 'Cheap Chinese' stuff is embarrassing the 'Big Boys'. Im thinking of giving the PrimaLuna a shot. Whos using what speakers?....cheap Chinese might be just the thing for this cheap American.

I'm using the One with my Martin Logan ReQuests. Makes the ML's sing!!

Using Audio Physic Yara floorstanders with Prologue I, and am really enjoying the combo. I auditioned the Prologue with Sonus Faber Concertos, which is a superb speaker.
