Effortless sound comes with a proper amplifier match to a given set of speakers.
Obviously HE speakers need the least amount of quality power to deliver fast, responsive effortless sound without strain.

My 86db large british monitors sounded exceptionally dynamc and effortless being driven by a high current Bipolar transistor amplifier with 300 WPC. The results were literally startling.
