Good link.
Those kind of 'quality' numbers don't impress me as much as the raw data, however. I like to see both impedance against frequency and Phase Angle against frequency combined into a 'Smith Chart'. This says it all, electrically speaking. Phase Angle is the 'missing link' in the good load / bad load debate which rages in the speaker postings. My current hungry panels, though no less than 4 ohms, are really not a bad load. Moderate phase means that more amp power actually makes it to the room as sound.
For some reason, people really LOVE numbers. All those awful sounding Japanese amps from the 80s, with incredibly low distortion numbers and high NFB didn't alway sound good, or sometimes even 'right'.
Is it time to begin discussing power supply regulation? A couple generations of NAD equipment ago, you could get an amp with an astounding 6db of dynamic power. So, what do you want? Pure RMS with little headroom? Or would you like a smaller RMS rating with huge peaks? I have no answer, only asking the question.
Enjoy whatever you end up with, That's all that counts!
