Eh... not big on modern tube gear. It mainly strikes me as a fad to fleece people out of money, and often (A) doesn't sound much if any better (a lot of lower-end modern tube equipment even underpowers the tubes... and as a matter of audio "purity," transistors are better because they have lower distortion), and (B) is priced far above what any difference from conventional solid-state gear is worth. The big exception, of course, is guitar amplifiers, where solid state gear is very apparent and the "tube sound" is almost universally preferred.
What I *do* like is taking old things and making them useful again, reducing waste, and choosing things that are built to last. That led me to start getting interested in antique radios, which I've always liked from an aesthetic standpoint. Sure, the big 1938 Zenith console in my living room doesn't have anything approaching the features or the treble response of even a low-end modern receiver. But it's been working since 1938, which means both that it's kept out of the landfill and that it's one less modern piece of junk that needs to be made, if and when something goes wrong it's easy enough to fix that it will likely far outlast me, it does its job, and it looks damn cool doing it.
A modern component would have more features, and sound "better" (subjectively, of course; I don't want to get into the accuracy vs. warmth debate here) while it works... but it's got no character to it, no history, and when it breaks in five or ten or twenty years it's done. The Zenith is all point-to-point hand wiring with standardized, documented, and easily replaceable components. With proper maintenance, it could effectively last forever.
That's sort of our philosophy with a lot of things. We try to stick as much as we can to mechanical clocks, hand tools, human powered implements (one of the family heirlooms we're inheriting is a treadle sewing machine, and I've also been looking at buying a pedaled scroll saw), we cook with cast iron, and we ride bicycles whenever we can. I've even started using a straight razor, both for the cleaner shave and because I was sick of having to buy and throw out disposables all the time. I'm not opposed to the new, but it's not as interesting to me. I like things that tell a story, and my greatest appreciation is for things that are built to last. Few things are, any more.
It's a lifestyle as much as it is an aesthetic.
