From almost the first moment I heard the 808.2 and 7200 combination it sounded special. The sense of scale, dynamics, clarity, clean bass and pure, extended treble were all apparent. Of course, not all this was doen to the 808.2: the 7200s played a part as well, including their bass alignment. But an extended listening trial at home over nearly three weeks only confirmed my impression that the 808.2 was doing something special.
Is the HD621 the fairest test of Meridian apodising? There seems to be general agreement that there are differences in ability between the G08.2, the HD621 and the 808.2, so not all apodising and upsampling are equal: hence the new 808.3.
And George's point that there is more than just apodising to the 808.2 is surely correct.
