ayre ex-8 2.0 output transistors

Looking at the ex-8 2.0 and the Aesthetix Mimas. Noticed ex-8 weighed about half of the Mimas. Investigated and was told that the ex-8 uses twice the output transistors so they can be biased at a lower level resulting in lower power consumption. Because of this less heat is generated so heat sinks can be removed resulting in lower weight. Does anybody know about this architecture and its effect on the sound? Is it unique to ayer?
Thx.

PS - I'm confident I'm my resply, above, but it's also fair to say, NEVER JUDGE AN AMP BY IT"S WEIGHT! :-)

Personally a huge Ayre fan, but it's got such a unique sound signature you will easilly hear which of those two amps you really want to take home.

Bias level isn't really a function of transistor count AFAIK, but different transistors may be well biased a lot colder.

The Sanders amplifiers use these as well. 

What the extra output transistors gives you is less of a need for feedback.
