Why compare monoblocks with higher power (and cost)against stereo amplifiers with lower power (and cost) thinking it reflects on the absolute amplifier quality? The only thing that can be determined is which is a better match for the speakers being used.
And yes, the more powerful and more expensive amplifiers may be better by some definitions but that does not diminish the performance of the lower power/cost amplifiers when appropriately matched with speakers.
