The Sony XDR-F1HD is very good in stock form. When modified by the XDR Guy, it is ridiculously good. Sensitivity and selectivity are unbelievable. The sound quality is top notch as well. I have a Philips tuner that is out for modifications/rebuild. It will be very interesting to compare the finished Philips to the XDR. The Philips has an unbelievable, sound quality wise, AM section. Never before has AM sounded so good, to these ears.
