It only makes sense doesn't it ? A receiver is (in most cases) a series of compromises.It attempts to fit a switching matrix,preamp,processor,tuner and amplifier into a somewhat more compact chassis,while hopefully (at least in theory) making its various features and functions more easily utilized .
While convenient in many ways (at least functionally) ,the most compromise is usually in the area of amplification.As you are in agreement with me on the subject of " the value of good amplification" I also am in agreement with you when it comes to the F.T.C..I think they should introduce a stricter and more standardized way of rating surround sound receivers' amplifiers. Manufacturers should be required to post the true power output of a receiver's amplifier with all channels driven and it should be full a full bandwidth rating - from 20hz to 20khz . I believe that this will allow the consumer to make more informed decisions, while also allowing the consumer to see the value in higher quality amplification.
Also I believe that good clean amplification shouldn't be exclusive to the high end. There needs to be a better variety of affordable, high quality amplification, from recognized brands, and not just internet based companies.If I could afford it , I too would utilize separate amplification for every channel,my wife would think I was crazy but oh well I've been called worse...LOL.
By the way in reference to the extra, left over channel in the aforementioned systems, what do you think of( if so equipped) either bi-amping the center speaker ,or even run two centers ?
