I got one for my son and while it is not a full 5.1/7.1 surround sound it really does sound good. He has his x box linked up to it and the effects and voices sound like the thrill rides in Florida. I wouldn’t pay the £800 supposed full price but for £199 on Sky vip they are good. I actually paid £100 new for mine from someone who was selling it still sealed.
I have had one for around a year or so. It is good. Certainly not worth the "non Sky" purchase price. I paid £200 or £250 i think. Good value.
