Im hopefully now changing my speakers to Monitor Audio RS8's, RSFX or RS1s for rears and the RSLCR centre i was wondering whether to get the RSW12 sub or keep my Rel Stampede which i know was a 5 star award winner a few years back im guessing the monitor audio will integrate better in the system is it a better sub? Ive always liked the Rel. Im also guessing the RSFX are better as rears over the RS1's? Thanks
