if you're looking for very good AV receivers, i suggest you do some research and find models which are certified to supply equal, true continouous power to all channels in demand....

most of the models out in the market are not capable of doing this... these models claim that their amps can supply high wattage (100++ watts) of equal power to all channels... but in reality, this only happens mostly for the front channels...

the situation worsens when there is a need for all channels to be driven at high levels... the fronts drop down to 70-80 watts (out of 100++) and the surrounds even worse to about 35-40 watts only...
