I own both the Sansui 717 and 5900. Audio quality is good on the 717, just fair on the 5900. Neither are particularly good for DXing though it is about time that I upgraded my aerial. My Fisher FM-1000 is by far the best of the several tuners that I own; DXing with a dipole is easy and the audio quality is out of sight. I have owned most of the Mac tuners as well as the REL and the Fisher is just my favorite.
