The metal box that surrounds the power supply in most decent receivers is called a Faraday cage and its purpose is to shield emi from the rest of the analog pre-amp signals. Digital signals are a little more immune to emi than the low level analog signals. In these designs, you would be very hard pressed to here emi interference coming out of your speakers even under no signal conditions and at full volume.
Yep, I agree with everything you said, and am aware of this approach. It is used in computers as well as in amplifiers.
I disagree. The whole a/v chain is as good as it weakest link so if you hooked crap up anywhere in your chain, then your gonna hear crap coming out of your speakers. I think the whole thing revolves around balance and if you have certain quality of speaker, you want to ensure that the rest o fthe chain is of similar quality to get the most out of your system, unless off course, you have a planned upgrade path in mind.
I find that the largest level of Crap is from the speakers themselves. I have heard my speakers on a $400 A/V Receiver Sony Receiver (when they had $400 4Ohm Receivers), and it sounded wonderfully. I also had used a $60 5 disc CD-Changer for the test, and a $100 DVD player. They both sounded amazing.
I really beleive that you should spend ALLOT more on your speakers then on your AMP, or AV Receiver. But I guess this is a case by case situation. I am sure there are some REALLY bad receivers that wouldnt make anything sound good
The problem with low quality Amps (or AV receivers) seems to be clipping at high outputs, and not sound quality. These rules change when your talking about more expensive speakers then the Sub $1000 (a pair) speaker ranges I am talking about.
With the digital tech improving in AV receivers and the introduction of distributed digital video with new standards such as HDMI, HD-DVD/BLUE RAY, and the evolution of communication between components that will most certainly come... I beleive that the time is right NOT to spend allot of money on a high end A/V receiver, unless you have the money to upgrade in 4 or 5 years (which I dont).
I acknowledge that my aproach and views are not the only valid ideas out their, and that everyone has to make their own choice... Audio is just like choosing your favorite hamburger

You can not use weight as a reliable method for estimating power output capability. At less then 50lbs, the Behringer EP2500 amplifier outputs a measured 2,100-2,400 watts(depending on frequency), unclipped, into 4 ohms.
You can also use weight as a reliable method of judgeing the mid and base drivers quality. Of course, as with the above example, this only takes you so far.
Maybe the cheaper amps should include a BRICK enclosure that will allow BOSE (and other) salesmen to add BRICKS to their components, to make sure they FEEL like they are high quality. I can just imageine the poor shmo that finds a cinderblock in his "high end" receiver.
