Bottom Line:   
Superbe amplifier (2013 model).

The hybrid construction with the 12AX7 tube in the preamp stage couple with a MOSFET class A amp is the perfect combination. Nicely built from the outside to the inside. The speakers and RCA terminals are super solid.

The only thing that I would say is that remote could be more precise. I meen the boutons are very picky. The remote itself is a peace of art...

I changed the factory Tung Sol tube to a NOS Raytheon (12AX7A since 1963) witch makes a huge difference. The fact that there is only one Tube makes changes very cheap. I can dream one day to try a NOS Telefunken without saling my house.

Couple with good cables makes the amp just perfect!
Highly recommanded!
