<< I have the Pioneer DV 79i player and TSX59i receiver and have them connected via iLink. Really is outstanding sound. >>
The question I have is whether it sounds better than simply using an analog connection. There are only two reasons that it could:
a) The digital-to-audio circuitry in the receiver is better than the comparable circuitry in the DVD player. I doubt this is the case.
b) If you are using special digital features in the receiver (such as room correction), then any analog signal would have be re-digitized, processed, and then reconverted to analog.
But if you do your time delays and bass management in the DVD player setup menus, with no further digital processing in the receiver, I would expect the iLink and the analog connections to sound very similar.
<< Sad that the licensing fees killed iLink and is replaced by HDMI though based upon what I have read HDMI does not do such a good job on Cds of all things >>
iLink is $15,000 per year, plus it is ridiculously complex for what it needs to do. That is why it was never used by a high-end manufacturer.
HDMI is broken for audio from the get-go because there is no separate audio clock signal. The audio clock is derived from the video clock. I was in discussions with the main forces setting the HDMI standards and begged them to include a separate audio clock signal.
They refused to do so. Do you know why? They had already designed the connector and there weren't any extra pins left. It took another year or two before HDMI came to market, so there was plenty of time to make a change to the connector. But they couldn't be bothered. (It's kind a crummy connector anyway. There isn't any latching mechanism and it can fall out easily if the cable is not super small and super flexible.)
Oh, and by the way, HDMI is $30,000 per year -- $15,000 for HDMI, plus $15,000 for HDCP (the copy protection that is mandatory for using HDMI with DVD players). So don't expect many high-end companies to make HDMI DAC's either...
