Fronts are Monitor Audio GR60s. Centre is Monitor Audio GR Centre. Amp currently is a Yamaha DSP Z9 but I'm going to get a Yamaha RX-A2050 instead. i'd prefer a 3050 but I can't afford the extra cost. My budget for the pair would be approx. £200. Is this doable? They don't necessarily need to be Monitor Audio. Cheers in advance.
