The last purchase to complete my home theater is a two channel amp: The top contendors are:
Anthem MCA20 (225wpc / 190w x2 all channels driven) for my fronts use the MCA30 for center and rears.
Anthem PVA2 (120wpc / 105w x2 all channels driven) for my rears.
Crown or Behringer 200+ watt pro audio amp for my fronts / MCA 30 for my center and rears.
My question is how important is it to have matching wattages between speakers . amps. Already my fronts have 4db Sensativity Difference meaning i will have to turn the other channels down or turn their channel up. Does this mean i should get a higher wattage amplifier, in which case maybe i will have to adjust the levels less.
What happens if i have 200 watt amps for front 3, and 100 watt for rear speakers, does that mean my output will be limited by the lowest amplifier rating? or does that just mean that there will be less headroom and more distortion on my rear channels then my fronts? Can i easily get 75dbs with little to no distortion from a 105 watt amp from speakers with 90db sensativity
I have an SPL meter, so calibration won't be an issue, i just want to make sure i can set it at THX levels (75db) and not be introducing any bottlenecks in my system by having too many or too little watts on my new amps / to my speakers.
