To be fair, I was slightly wary of spending so much on this type of unit but I went for the full blown matrix version versus the 'standard' HDMI because 1. I did not want to have to have separate power supply for the modules behind the TV's and 2. I took the decision that it was probably worth future proofing my system given how quickly things change in this dept! Having said that, I am so glad I did given all I can say is that I am seriously impressed. I literally just plugged in the source's into the back of the matrix, turned on the power and had HDMI quality instantly. Although my house has also just be rewired with Cat 6, I don't utilise the 4K part of the system as yet but all the IR's work (once you've located the receiver's on the hard drive/sky boxes!) very well and it's as if I have full HD picture on the TV with the sky box just feet away (my boxes are in a cupboard under the stairs and 'run' 4 x tv's.) I reckon you get what you pay for in life (most of the time!) and although the price of this type of equipment will surely come down (again!) as more and more people start using/wanting it, I am happy to pay what I have for the picture that I have! Lastly, I cannot rate Seb at A Class highly enough either. He was always on the end of the phone and was even emailing me back on a Friday night/sat morning when I was struggling with something. His knowledge is very impressive (as you would expect maybe!) but his customer 'service' is in a different league to what I experience most days. Seriously impressive.

I contacted A Class Technology requesting advice on 4x4 matrix's that would be appropriate for my home installation. Seb processed my query, he provided an excellent service and always provided an instant reply. He provided me with detailed advice and clearly explained the options that were available to me. After discussing my requirements I was recommended the AClass 4k2k 4x4 matrix. Seb and I collectively comparing this product with its competitors and it was clear to see that it was considerably cheaper and provide more features, so I decided to purchase the product. Seb continued to provide excellent after sales support to aid me with the installation. I would strongly recommend the services of A Class Technology.
