Just checked up on the specs, and seems they use 12AX7 and 6N1P's which should easily last upto 10,000 and 5,000 hrs respectively. Easy to obtain and are not too expensive. The design accommodates tube rolling, so one can replace the stock chinese tubes with better ones, for a noticeable improvement and can add different flavors to the sound. Has good power at 150W/8 ohms. Goes to 250W/4 ohms, which is close to doubling, so shows a healthy and robust power supply. First 10 W in class A, which is what most of us actually use. Considering the possibility of tube rolling and high bias class A design, I think it is safe to assume, that it wont sound bright or shrill ( Infact i think this will sound rich and lush ). And this comes very close to the holy grail of tube pre + class A power combo, in a single box.
And the best part is the build...simply impressive. If this was built in japan, or Europe, we could look at easily 3 times the asking price. Anyways, I will stop now, before I start sounding like a Vincent salesman
