Hate to be a kill joy but it sounds like you might have a system turned on many hours of the day, many days of the week.
I think you'd go through tubes rather quickly with that many hours of usage each week. Maybe a hybrid design would give you the warm sound you're looking for with less tube issues.
While vinyl might be a nice thing to do at certain times, I'd also add in a music server you Can load play lists and let our do its thing for hours while guests come and go.
Or they could add their own choices via ipad.
The point someone made about the sweet spot is a good observation.
Also I'd do 4 subs around the room for even bass with less nodes.
