I am very pleased with my HD621 acquired 3 weeks ago and at peace with the (to me) substantial cost. Many thanks to this forum for a better price via an import to the U.S. from a dealer in France who responded to one of my inquiries on a thread in late December with a favorable price offer. I bought an unmodded Oppo BDP83 at the same time. After installing the HD621 1.05 firmware update I then spent many hours with configuration with the HD621 and G68. I am in bliss with redbook CD sound quality but have found real differences in the quality of SACDs originating from recordings in different eras. I have not spent enough time on DVD-A, DVD or BR-DVD to have much of a sense of what HD621 is contributing to sound quality in those formats.
