PSX to HDMI to Soundboard
Cable to HDmi to Soundboard -- HDMI to SOny bravia .
Would using high speed cable for PSX to Sounboard enhance PQ or AQ?
I don't believe so. As long as you are using HDMI cables or in some cases an Optical cable ( for Audio) you should be okay with AQ and PQ. The only other caveat are older 1.3 standard ver HDMI cables don't support 3D. You would need the newer HDMI cables to support 3D. ( the key is to avoid using the old component cables with the 550W to process audio)
Also, it can be hard to tell by the markings on an HDMI or package if its high speed or not since manufacturers use different labeling criteria. Best to just try out what you already have like you mention. If however you are purchasing new HDMI cables then look for the 1.4 version in the specs ( sometimes called High Speed).
Another way to look at HDMI cables for PQ:
"-Standard-speed HDMI cables are rated
up to 1080i.
-High-speed HDMI cables are rated
well above 1080p."
Some cables will do more than what they are rated for, but again depends on the manufacturer--hence my recommendation if you look to buy new cables to just buy the latest inexpensive 1.4x standard/version to cover all your bases.
