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

I am running a Modafferi-refurbed McIntosh MR78 in my music system.

Tuners in storage are Acoustic Research Tuner, Magnum Dynalab Etude, and SAE 8000. Gave away my Classe Tuner 1.

And tuner sections reside in random other components, like Magnum Dynalab MD208 receiver, Emotiva PrePro, etc.

In my experience the Modafferi modded MR78 and the last Sequerra are about equal and as good as tuners get.  Or put another way they and some of the others mentioned exceed the best broadcasts available that I can find.  Years ago we could listen to live performances that had great sound, but for my environment these are no longer available.  And good luck finding a good antenna these days.

This may not be much, but for other/secondary FM use, the Nakamichi Soundspace 5 radio is super for what it is and for the used prices it seems to bring...and for a bit more in a secondary use, the Nakamichi SR-3 receiver is an early, Nelson Pass influenced, superb receiver for secondary use...or a college dorm, etc. 

Sequerra was pretty good back then, but they broke a lot.  Also, big in the day was the Onkyo T-9090; it was great.  Still going for big money these days.  I have an older Onkyo T-4055, the T-9090 precursor, and it still plays pretty well!

Cheers!

I shopped for vintage high-end tuners about 10 years ago and found out that several of the earlier Kenwoods were excellent, topped by the 600t or 650t. Also the Accuphase T100 and T101 (which is the only one I still have). Also the earlier Sansuis. Anything modified by Modafferi or Antenna Performance is a very good bet.  Enjoy!
