I'd just like to reiterate, you might get some really interesting discussion on the pass labs section of diyaudio. As you can tell above, Nelson's designs are cited both as evidence in support of paralleling devices, and for simplifying and getting down to minimal parts. Because of that, the crowd over there is actually supportive of both approaches and might give you some additional thoughts once the thread here runs its course.
Paralleled Transistors
Is there any truth to the argument that many paralleled output transistors, despite strong attempts to match closely, will smear music signals as they are not identical. How about those designers. using only N channel mosfet pairs rather than complimentary P Channel devices? Just curious whether using larger more powerful Mosfets, and thus fewer pairs, is better in any way than let’s say 12 smaller pairs (24) per channel? Thanks for helping me to understand.
