That is a dream room for sure. Wow!
Those are really great looking amps too. Part of the connection to these is seeing the lit filaments, right? I've often wondered why tube pre's aren't made the same way, especially a premium product like the Dude, a little window or means to see the tube, perhaps even exposed. With amps you don't have a choice, but I would think even on a pre you'd want the visual cue.
