Who Here Owns a Sansui 919? Please describe performance vs other tunersi

Are you referring to a TU-919?

The tuner on my 9090DB is better performer  than my McIntosh MR-78 by a long shot, and the Mac is no slouch.  I would imagine the TU-919 would be similar.  Sansui is very sensitive, and extremely quite.  It also never drifts and I’m using nothing more than a dipole antenna.

You're McIntosh tuner obviously needs repair, alignment, or adjustment for this result that you report here to be factual, accurate, and true.
