Is this enough power?

Surely!

Happy Listening

speaker and amp specs tell only part of the story and the power needed varies based on design etc...

keeping this in mind, looks like a decent match imo

If the speakers are of moderate phase angle, you're good to go.

Large phase angles or large phase angles at impedance mins will tax the amp.

A key factor is the dynamic range of the music you are listening to (the difference in volume between the loudest and softest notes). You mentioned listening to classical music. Well recorded, minimally compressed classical symphonic music can often require 1,000 times as much power on brief peaks as on soft notes (1000x power = a 30db difference in volume).

So I would expect, for instance, that the system would have problems dealing with the bass drum on many of the older Telarc recordings. Likewise for some (many?) well engineered symphonic recordings on other labels.

Jazz and chamber music I would expect to generally be no problem.
