A/V receivers with preamp out jacks can send processed audio data to an M3a multichannel amplifier for a dramatic increase in power and quality. Many of the latest multi-channel receivers contain high quality preamps and processor chips. You will not need the amplifier section for most or all of the main system, so the less expensive, low power models are ideal. A hi-value option is to use the 3 channel series for the 3 front speakers where approximately 65% of all power is required. This takes a major load off of the receiver power supply so it can provide higher current levels to the surround channels.
