Do any still use an older high end tuner from the past?....

I came across a Kenwood KT 5500(1979) in pristine condition. Truly an entry level tuner, but, according to my technician it has alot of the same components that Kenwood used in their higher end models. It just has a cheaper chassis. We cleaned it up, re-tuned it and installed blue LEDs so it would match my existing modern equipment. Works just fine for me as I only occasionally listen to the radio.

Luxman T-110. Still working and looking great.

Still using a Sansui TU-9900 for 42 years now.  Sounds great with WBGO Jazz station out of Newark NJ.  Available on the web as well (of course), its a listener supported station, hence no commercials, but the occasional fund raiser. 

I use a Mitsubishi DA-F10 (bought new) every day, as well as a Nikko Gamma 20 in the office. We have outstanding FM in our area: an NPR cluster offering separate jazz, classical, college/progressive and mainstream public (talk) stations. Available streaming as well, of course. A part of life I would be saddened to lose.

I have a Magnum Dynalab Etude that I listen to every day while working from home.  I live a long way from the big broadcasters, but have a rooftop antenna and get pretty decent reception of the local NPR news/jazz station.  I also have an Onkyo T-9090 II and a Marantz ST-17 (which is not quite as "high-end").

Both the Etude and the Onkyo can deliver close to CD quality with a good station and a good signal, both of which are a little hard to get in the remote area where I live.
