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

I love my Yamaha T-1. It is all analogue and sounds smooth and warm. Has variable output also. I remember in the early 80,s seeing this tuner with other Yamaha separates paired with Perreux amps and ADS speakers, The Tuner sounds great still! 

I run a NAD 4150. It is probably the cleanest tuner I have ever used.

I love radio, have a Mac MR71, 67, 74.  The 71 and 67 sound the best but with the hassle of finding someone to do repair work on them i ended up with an alternative. And I live in an area (Northern Colorado) that has at least 7-8 very good stations

I bought a new CDP with dac-Emotiva ERC4, with a schitt etr spdif i am now streaming radio as well as itunes. The Emotiva has a very rich full sound, not as fantastic as the MR71 but close. May not go back to a tuner except for my cabin in the mountains with no internet.

For years I ran a KLH model eighteen which I had modified by installing crystals in the IF section and got rid of the IF transformers. I also updated the audio portion to sound a bit smoother- after changing out all the filter caps. Regulating its supply helped too, but I couldn't get around the fact that it simply didn't have enough selectivity in the front end (one of my favorite stations is really low power and right beside a behemoth country station). So I'm on the hunt for an old Kenwood...

Kenwood, formerly Trio Electronics of Japan, has long been a supplier of communications gear to the ham radio community, as well as for other applications.  Presumably that has contributed to their expertise in producing some well regarded tuners.
