Hi folks,

While looking at some 5.1- and 6.1-channels amplifier / receiver / speaker
systems to be used with a new DVD recorder, I noticed that power is rated
in the format: "xxx watts @ 1kHz @ .7% THD".

Now, I will admit to being out of the technical end of the audio field for a
number of years, but are ratings no longer based on " xxx watts RMS per
channel @ 20 - 20,000 Hz @ .xx% THD" ?

Looking at a couple of stand-alone receivers (no speakers included) found
the same type of rating.

My impression is that this is related to the use of switching power supplies
in the new systems.
Is it no longer a case of 'good specs' but rather 'how it sounds sitting on
the shelf at BestBuy' ?

Thanks for any opinions.
