Re: Neptune EQ
You make an interesting point about HDMI 1.3 and the A/D - D/A issue however there isn't ONE high end company with it enough to have HDMI 1.3 working right in an AV preamp (exclusing Denon and Integra) let alone to do room correction on it.
The question you have to ask yourself with Neptune is - is the audio difference from HDMI for your movies more impactful than tuning your speakers to your room. My money is - having had every room I have ever owned professionally tuned with EQ - that they EQ will make a bigger difference.
Further down the road - I would bet that an HDMI 1.3 version would be reasonable. For now - its now. CEDIA this Sept will tell us a lot.
