Perfect Voltage Source -- how important?

Dear All,

I have a question regarding the ideal of an amplifier behaving like a perfect voltage source. Reading some amplifier reviews, and some of JA's very informative measurements, it would seem that some of the more expensive ones do indeed behave like the perfect voltage source, ie doubling their power from 8 into 4 into 2 ohms speaker loads. I also notice that some good and/or expensive amps don't (or can't) -- Chord Electronics is a case that comes to mind. Most of their amplifiers seem to be real powerhouses, but I don't think any of them (apart perhaps from one
