@big_greg , offers excellent advice. When it comes to tuners, like real estate, it comes down to; "location, location, location"
FWIW, IME, Magnum Dynalab’s own cheaper (though still somewhat expensive for what it is) previously called "silver ribbon", presently called SR-100 worked better than their own more expensive ST-2 or the Fanfare equivalent.
While the Magnum Dynalab’s tuners are very good quality, for under $300 you might find better value from some of the offerings from Luxman, Denon etc..
Again, consider what @big_greg posted, and seek a tuner that has favorable specs for your particular needs, whether that be sensitivity or selectivity.
