What are some of the better tuners out there?

I have a  Magnum Dynalab Etude and an Onkyo Integra T9090 II.  Both are great, the Etude has a little more body. 

Yes, there are radio stations available on streaming.  While I'm a fan of high res streaming services like Qobuz, most radio station streams are very poor quality and don't come anywhere close to the sound quality of a good station played on a good tuner.

fmtunerinfo is where you'll find the big tuner shootout and lots of other good stuff.
