OK, so here is a theory as to why one HDMI cable can be different from another and so produce a different result. My source of my theory is an advert for a QED HDMI cable in last months What hifi (quote your sources). 'In an HDMI cable the signal changes direction around 4.5 billion times a second, so it is fully accepted that errors will occur.....HDMI products use complicated electronic error correction....simply to eliminate the risk of such errors....'. So QED state they provide 'significantly higher levels of headroom in our HDMI cables-extra tolerance.........to minimise any risk of signal error.'
From previous posts there does appear to an acceptance that errors can occur, but over long runs of cable. QED are stating that errors occur at all times and the action that they take to reduce such errors. Could it be a case that errors do occur over short runs and do QED's claims make scientific sense?
Del Smith, please share your thoughts, cable, your mind or both acting together!
Well...alright then, as it's the 100th post on the subject.
I had 10m of Profigild PGV1010 going into my PJ, at the recent Bristol show (Loved the show by the way)I bought 15m of QED Qunex cable.
My thoughts were if it isn't better than what I have then at least I can move the PJ back a bit so it's not such an eye sore, so it wouldn't be a waist in that respect.
Anyway before going in head first I did a test between the two cables, my receiver has two outputs and the PJ has upto three inputs, so what I did was freeze a picture on my Sky HD box and flicked between two of the inputs on the PJ.
The difference wasn't massive but I did see a difference straight away, and then swapped the outputs on the receiver end to see if the difference might be there.
I then got the misses to have a look and tell me if she could see a difference, her answer was the same as what I thought, so I wasn't going mad.
The difference that we could both see was not the quality of the detail but the vibrancy of the colours, the definition was the same. As for sound, it's not used on the PJ so can't answer that one but I will say that at the moment the inputs to my receiver doesn't have top rated cables but I shall get at least one to test the audio side of things.
Will also try some mains conditioning as well soon.
