I currently have a sony dav dz500f but because it is very outdated it dosent have an optical and therefore i cannot play dts tracks off my ps3, i thought about connecting them to my Yamaha DSP 630 amp but it has a rated impendance of 2.7 and the minimum is 6 ohms on the amp so i have heard it is unsafe connect it, seeing as my current setup is virtually use less i have two B&W DM 302 speakers that i am going to use as my front two speakers i am looking for two rears, centre and a sub not too expensive but good enough to deliver a decent amount of bass and give a good cinema experiance.. any suggestions would be great.. Thanks
