I have just invested in the monitor audio S6 fronts and SLCR centre, which are currently winging their way to me. I have got an option to get some RSFX ( the new model but as far as I know only cosmetically different) at a good price. This would be as a replacement for my Eltax HT2 bipolar rears. Is it worth upgrading? The HT2s are generally well regarded, but would they be outclassed by the MAs? Any input greatly appreciated.
