I'd love to answer but there are so many variables it would take a small book. But all things being equal my friend George Bischoff who built triode tube amps(Melos) with over 400 watts/channel always said a good big amp will beat a good small amp every time. Notice the word good which encompasses many things. But it will always include a superior power supply which is costly and can be compromised without affecting standard specs.
Why do speakers improve with more powerful amps?
So, if I have a solid state amp that more than adequately powers a speaker, why do people recommend a larger more powerful amplifier to improve things?
Why do more powerful amplifiers impact speaker sound quality in a favorable way? Is it because more power is reaching the speakers? Mid and Tweeter drivers I was told receive a reduced signal versus bass drivers which receive relatively more power via crossovers. All for the purpose of balancing a signal going to the various drivers.
