I have owned a 350A Reference stereo amp, and presently own a pair of 150A Reference monos. IMO, the 150A Reference monos are a significant improvement over a 350A Reference stereo amp...larger image, lower noise floor, overall more refined sound.
This of course was in my system, so YMMV.
The 150A Reference monos also produce double the power of the 350A Reference stereo (500wpc versus 250wpc).
