My summary opinion: The SOURCE is vastly more important than the Tuner or Streaming DAC setup.
This seems to be a resurrection of a fairly old discussion string, and I have learned & experienced a few things since the discussion origination with regard to tuners and streaming. I believe all of my comments should fall within proper decorum for Mr. VanAlstine's circle.
First, tried a few different tuners attempting to get good / better sound from local radio stations when living in Omaha, Nebraska, and Minneapolis MN. I tried an older Aadcom, decent Kenwood receiver, a stock Kenwood 7500, and lastly a very nicely refurbished Scott 355 $$$. This last unit "should" have offered a sublime listening experience, but it just didn't happen. I really wanted to enjoy the local Christian Radio station ( KTIS ) with good fidelity , but the sound quality was only mediocre with anything I tried.
During my quest for great radio on some road trip through Ohio and Kentucky I had the pleasure of finding Mama Jazz
https://www.daytondailynews.com/news/local/radio-personality-mama-jazz-dies/AHAx6dvHGYVO1utfz12ngK/ and the sound quality on my car radio was glorious ! Wow! If this radio station was local, I would indeed listen to it. Amazing!
I then realized the most critically important part of having great sound quality over the radio was the SOURCE. The public radio SOURCE for Mama Jazz was playing excellent recordings AND I believe had excellent broadcast fidelity too. It was truly amazing. Unfortunately, this excellence is NOT pervasively present with other radio stations - including my own beloved Christian radio station. I love the content, but the quality was mediocre. And, the radio station broadcast is perhaps 10 miles from my home.
So.... I ended my quest for great fidelity from my local favorite radio station after multiple tuners and many failed attempts. Since Mr. VanAlstine and I both live in the same metro-area, perhaps he might be willing to share his enjoyment or difficulties.
If "you" find a great sounding local radio station that you really enjoy - wonderful! Buy a great tuner! Use a great tuner! Enjoy a great tuner! If you live in southern Ohio or Northern Kentucky in the USA, there is likely a terrific local jazz radio station. Mama Jazz has passed, but the terrific radio station fidelity might still be broadcasting.
Then, streaming.
This was similarly difficult, BUT there are vastly more radio stations available streaming than radio broadcast. The likelihood of finding an enjoyable streaming radio station is better than local radio station because there are soooooo many more streaming stations! It would seem like streaming music FROM a radio station would be simple, easy, and cheap - nope.
About 6 years ago I had a discussion with a gentlemen at our church who was involved in the streaming audio and video broadcast for our Sunday church service. He explained that the cost associated with BROADCAST streaming for audio (and video) was expensive. I vaguely recall the cost was about $2k monthly for decent quality streaming broadcast - depending on the number of subscribers using the service. I am sure the environment has evolved digitally, but bandwidth is not free.
Where am I now with regard to radio and streaming....
1. I enjoy Minnesota sports-talk radio mostly and occasionally the mediocre quality of KTIS Christian radio. Perhaps my most enjoyable listening is sports talk radio on a humble radio while tinkering with a car in my garage

.
2. If I want quality, I stream TIDAL music. The quality of streaming music from TIDAL is extremely good.
Also, on the fringe on my knowledge and understanding.... several years ago at the Minnesota Audio Society monthly gathering, a sound engineer provided insight to the "loudness wars". He explained that artists want their music to sound louder so it "stands-out" from the rest of the music on the radio. The result is considerable compression and clipping for the music peaks so the average loudness of a particular music track is increased. The sound engineer also explained that overseas the radio standard was much better for the audiophile - mandating the average loudness for a music track at much lower level than in the USA. I believe the USA had no mandate for radio loudness averaging at the time, but England (maybe Europe) had a legislated / legal mandate with the average of about 23db. So, the gents across the pond in England / Europe should have much better radio - at least with regard to loudness and clipping.
Hopefully my comments might be of some help for the potential radio enthusiast
