Rogue SPhinx would be a nice fit into my second system if needed someday. By the time I need to change there, I'm expecting affordable tube/Class D integrateds to be even better and more common than today.
Personally, I would also love to build a second system around a nice VAC tube integrated someday, but not using tubes in the power amp makes for less maintenance and using Class D amps opens up a lot of choices for good speakers in a smaller package that might not work as well with a tube power amp.
