Hi again, can anyone tell me what's supposedly the best settings on my Pioneer LX83 amp for great sound for movies,music & TV. It seems to use a lot of different Dolby, Neo & THX settings, but the instruction booklet doesn't explain each one clearly. I know a lot is down to personal taste, but i'd imagine that one format is supposed to be far more advanced than the others. Also it states only use THX if your speakers are compatible. I'm currently using 4 x KEF XQ5s with a XQ2c centre & a KEF PSW3500 subwoofer and presume they're compatible but dont know for sure. Any advice please boys.
