Please do listen carefully and read this review very careful to understand it .However I am ask you and anybody please don't be foolish to spend you money on the expensive HDMI Cables isn't worth it, you are just waste you money. I have said that because from the experience and read a lots of rubbish about HDMI and lots of rubbish from customer services on the high street shops just ripping you off. whether you believe me or not don't spend anything over £20 to buy HDMI cables. If you do I can guarantee that you will regret and won't get or see any difference from similar cables for just £4.99 that could give you better picture quality.
I would recommend you always buy the proper original HDMI From the same manufacture of the your product to match the calibration in another word setting of the item from manufacture, do to those cables are tested against their product and calibrated for the best picture quality.
Eg. if you have Sony TV buy Sony HDMI cables or if you have Panasonic TV please do buy Panasonic HDMI, this are the only way or the best way to enjoying you product and picture quality. because they have been test and calibrated to match the best picture quality from you item. But not because of buying expensive cables and you won't never ever get the best from you product.
However , Panasonic cables are the best and excellent for the Panasonic product like blu ray and Tv ,100% you won't disappointed it will give you the best picture quality.
many thanks for reading my review.
