Considered DIY switches for my speaker systems but people kept pointing out the hazards and damage which could ensue. The QED switch seems to be the answer, works very nicely and not that expensive.

Bought this last month as an alternative to a btech b12 which never worked properly. I can now have sound in just one room or both rather than having some sound in both

For a number (approx 12) we have bought from Richersounds as their service support and advice has been excellent. First purchase was a pioneer plasma 55inch, and today Alan at their London Covent Garden delivered again the service we have enjoyed...

A neat unit but wiring it was a real pain with limited working space and fiddly terminals. Volume on one set of speakers was very poor - but since for now I was only wiring two sets I used the third block and they worked fine.

Does what it says on the tin. Nicely made at a sensible price. Only used it for a short time so lets see how it performs over time.

I've used this now over the last few weeks and it is so easy and versatile to control the sound between different zones. Definitely recommend this.

This replaces a cheaper product which drove me nuts as it didn't work properly. As I listen to the radio a lot it makes it so much easier for me. I am really pleased with it and so glad that I bought it, now listening is a pleasure.

Bought a cheaper alternative, which, together with its warranty replacement, both gave problems. The QED unit works perfectly & retains excellent sound quality.
