I've owned the following tuners- Onkyo T9090II, Dynaco FM3, Magnum Dynalab MD105 and McIntosh MR78. I also had an MR71 in my home for a few days but it wasn't working right.
The T9090II was the most sensitive, somewhat dry sounding, the FM3 the least sensitive, with a bloated mid bass and rolled down treble. The I owned an MD105 for a while and thought it was quite good, and now I have the MR78 which so far I would say is the best tuner overall I've owned. I find its multiple filters and selectivity are genuinely useful. Note that the MR78 has been recapped.
