My interpretation is NuForce are suggesting to avoid the cost of getting the best from HDMI at the sink use analogue output from the player and benefit from their analogue mods -

"Extracting high-quality audio from Blu-ray players is problematic. The HDMI signal interleaves video and audio data which, upon decoding, produces an inherent jitter as high as 7nanoseconds (For comparison, a good CD player's jitter is in the picosecond range). In practical terms, it is difficult to properly decode HDMI audio without employing extensive reclocking circuits, thus pushing up the cost of a good HDMI audio pre-processor.

The simplest way to improve analog audio performance is at the source."

I think the reference to "jitter" relates to their DAC implementation and not HDMI or SPDIF output per se.

" * A sophisticated clocking scheme to suppress the audio data jitters � inherent in all video-based players � for all eight channels. An ultra stable VCXO generates audio clock that is completely asynchronous from the transport's clock. The result is a theoretical jitter of < 3ps (RMS) on both PCM and DSD streams."
