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

Most expensive tuner I have on hand (among several, including a tube stereo Scott) is a McIntosh MR77. In present use is a Mitsubishi (Diatone) DA-F10. Here in the Tampa/St.Pete area the only quality FM stations we have are WUSF 89.7 (NPR and Late Night Jazz) and WSMR 89.1 and 103.7 (Classical) . The rest of the dial remains a musical desert of commercial dreck!

The Mitsubishi DA-F10 and DA-F20 offer outstanding sound quality. And can be found for around $150 or less!

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.
