I need to find a quality solution to connect my surround speakers to my 5.1 amplifier wirelessly. To keep my wife happy I have agreed to find an alternate solution to stringing speaker cable across the front room. I have seen plenty of 2.4ghz solutions but frankly I have not been impressed by any 2.4ghz devices as they tend to pick up alot of interference and they really screw up the wifi network. I don't need a lot of range since the front room will be relatively small but signal quality is priority. Can anyone recommend any good solutions for this?

Wireless surround is never actually wireless at all. In fact you can creat more of a wired mess using wireless speakers. The speakers require a signal in order to drive them. While the signal is sent "wirelessly" from the front to the back, you still need to send the signal from the wireless reciever to the actual speaker. Plus, the wireless reciever must be powered, and therefore have to be located near power outlets.

Find better ways to run your wires to the back, either by utalizing trim around floors and doors, or using decrative covers for the wires.

i think Wireless surround actually is amuture in performance right now ( unless the cost is dosn't matter )with people have plenty of 2.4 ghz signal in the room

There are a number of problems with this. The first is that you want to send an analog signal. This means either sending the signal digitally (which means your signal will undergo d-a conversion at the amplifier, a-d conversion at the transmitter, and then d-a conversion at the receiver) which will lose quality as a result of the amount of a-d and d-a conversion taking place, or sending it as an analog signal (which means any interference will degrade the sound quality).

The second is the fact you don't want to use 2.4ghz. The reason many devices use this area of the spectrum is because it's unlicensed. If you use a licensed area of spectrum you have to pay to license it in every country you want to sell your product in. Since using unlicensed spectrum is cheaper, virtually everything from microwave ovens to wi-fi to cordless phones use the same area of spectrum. You are going to have trouble finding a cheap device which doesn't use an interference prone area of unlicensed spectrum.

The third is as said, each of your speakers needs a power source to drive it. For the price it would cost you to get a transmitter and receivers for each speaker you could probably pay an electrician to put wallplates next to the speakers and run the cabling from the speaker back to the amp through the wall.
