i remember in the 80s when i bought my first integrated amp (some Sansui model) with 125 W/ch.
i used it with speakers of about 86dB sensitivity.

got rid of it within a year because it could not even reproduce a solo piano at live levels; but i remember that the low frequencies were good and the rest too.
i liked this amp a lot, but not the low power.

i then bought a Hafler 500 which i still use.
