I'm in the process of buying components for my new system. I'm planning a 5.1 system built around the Monitor Audio Bronze BX system. For the fronts I'm using the Monitor Audio BX6. They are rated 150rms @ 4 ohms, 90db sensitivity. Which AVR do I need to power them and the other components (e.g. BXW10 sub, centre and likely BX1 or BX2 rears)? I like the look of the Sony STRDN1060, it's specs state; 7.2 Ch. 1155W A/V Receiver (165 W x 7 @ 6 ohms, 1 kHz, THD 0.9%) (6Ohms, 1kHz, 2ch driven) THD : 1% (6Ohms, 1kHz, 1ch driven) THD : 0.9% 6ohms, 20-20kHz, 2ch driven : 100 W + 100 W (6 ohms, 0.09% THD) 6Ohms, 1kHz, 2ch driven : 165 W (6 ohms, 0.9% THD) I fear this may not be powerful enough? I was hoping to budget £500 but will adjust upwards if it otherwise means having an underpowered system overall and wasting the speaker potential.
