erm... Taukeh, I am amazed by the amount of patience    that you have here trying to explain abt digital thingy    It is always good to share.

It is too hard to discuss any further. Btw, I have a few HDMI cables with me as I mentioned earlier. Audioquest HDMI, Giraffe HDMI, Panasonic original HDMI cable (1.3a), Pioneer freebie cable with nice cable jacket, Another one from Sharp, Another one cheap looking freebie cable from Panasonic, and 2 OEM China mari HDMI cable (5m & 10m). Oh yes, there is another one which has been given to a cust. Wireworld Chroma HDMI if my me didnt fail me  Tried all these with my cheapo system.

Maybe my age is catching up with me . My eyes didnt transmit any difference in PQ to my aging brain nor SQ to my ears.

Incidentally, there is a case with these few cheapo HDMI cables. Actually, it were meant to connect to the rows of LCD TVs in the shop. About half of them failed upon installation . No signal. Upon checking, the installer bend these fragile cables to put it through the shelf
