After researching several tuners and their test results by fmtunerinfo I posted my question at one of their sites.They told me my NAD 4300 was as good, if not better, than the ones I had asked about. That really surprised me as I had my heart set on a Phiiilps AH673. Loved the look of that unit.
Thanks to this thread, I know now to get a Godar antenna.
All the best,
