Gorgeous cabinets!
Are those Field coils? I see only two speaker wires and none for any electromagnets?

The combination of very rich people and unobtanium objects makes for crazy prices, try get a Cetron 300B for example...
Beauty is that there are alternatives costing pennies to the pound, and frequently they are as good or nearly as good. I recently listened to some Audio Note 300B amp, and sure it was nice and had something special it sounded 'like a 300B amp does', rich and lush as 300B typically does. We listened to some (admittedly probably pretty rare) 100$ mesh tube a while earlier, and that had spooky lifelike qualities to it that make me value it higher than a 300B.
Problem usually is that the alternatives are no drop in replacement, especially with tubes, so you need to either design from scratch or do some (sometimes extensive) modifations.
