Frank, You hit on exactly what I am getting at. The objective is to upsample and retime jitter-free. What difference does it make if this happens in the HD621 or the 861v6? The only answer that I can come up with is that the 861v6 has lower jitter. But I have not seen anything to back that up.

DSP6000, DSP5200, DSP5500VC, P300W, SW1600, G68, 568.2, HD621, G57, G55, Oppo BDP-105.
