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.

Very interesting and informative posts .....thank you to all. I recently auditioned a Danish Gato amplifier which uses one pair of large N Channel Mosfets per channel.(200/400/700 wpc) The sound was very pleasing, with a natural tonality, similar to a class A Gryphon type sound. Curious!

Thanks again for the helpful information! I guess paralleling transistors is the more favorable approach when intermediate and high power is desired. Brands like Gamut and Gato are the exceptions, using one pair of large N- Mosfets per channel.

This is off topic but I wonder if someone can briefly explain why my high power class A Clayton S-2000 amplifier draws 6.2 amps when first turned on and then drops to 4.2 amp draw after 25-30 minutes....perhaps it is stabilizing its class A bias?  Thank you to all respondents!
