FM Tuner for audiophiles-is it a bad idea today?

Only if you don't also get a decent antenna. 

I use FM tuner (Carver tx-11a) still for content not available elsewhere.  Special or hosted programming on public radio, etc.  Stuff you can't get with good quality streaming which does not include most published music anymore.

Had it on all Saturday afternoon.   My wife wanted Christmas music on the local station.

Bad for me. I purged mine years ago.
May be good for you.
There are NO stations here that are not available streamed, breakfast, lunch AND supper.

It's true most stations are streamed and will be a better option if fm signals are not strong and reception is noisy but resolution of many streamed local stations is not great and can vary so it still depends.

A good FM tuner will definitely help pull in the weaker stations clearly. The Carver is very good at that.

"The station I listen to spins vinyl, KCRW."

yyzsantabarbara-
I wasn't aware. Being in SoCal, I typically toggle between KJZZ & KUSD. Now and then I'll catch KCRW playing something cool, but since it's not a dedicated music station, it's a random pick when turning the dial on the Mac MR71.  

Radio is very different than 40 years ago. You have to dial in the public stations which require a good directional to get many of them.The public stations are the only way to hear "new",obscure,"deep cuts" or anything different than the commercial junk, and it's not full time. My 2 go-to's are pretty much all that's left dedicated to music full time.

The only drag with PBS is the guilt you develop during pledge week, if you're not a contributor.
