Update to my original review.
"My original review was about the delivery process, none of which was the company's fault, it was down to Royal Mail in the UK. The equipment is very substantial for relatively small speakers and despite having some trouble with my ARC control on the TV HDMI socket ( it only worked in and not out) the unit connected perfectly with the optical cable. connection via the unit to the speakers was seamless, the sub woofer not working was down to the delivered item being set to wired and not wireless, once the switch was flicked everything works fine, indeed having heared the sound without the sub and then with it, the sub definitely packs sufficient punch for the room its located in. The room i have the system in is quite small 7m by 5m and within this area i have to say that the sound is terrific, and i am very pleased with the equipment. Main use is currently for surround sound music via blu ray remastered audio and its 5 stars from me. Well worth the money, definitely would recommend to others."
