It really depends how loud you need them to get.Guys i got the B&W S684 s2 as front speakers in my 5.2.1 setup.
They are rated 25W - 150W into 8ohms on unclipped programme according to the specs.
I m happy with the performance so far with the T758 V3 & the speakers, when using 5.2.1 material i wonder if they are power starved? Should i add a power amp to my setup? if yes which Nad power amp you guys suggest?
Thanks a ton.
P.S- i m a noob when it comes to power amps.
B&W quotes 87dB/W/m sensitivity and 8ohm nominal impedance, falling to a minimum of 4ohms, and suggests amplifiers from 25W upwards will be sufficient to drive them.
At a distance of 3 meters, with 57 watts of amplifier power (and 3dB of headroom left on the amp), these will produce 92dB. That is about as far as this AVR will push them.
If you need more than 92dB, an external power amp would be needed.
