I use Zu Soul Supremes and I doubt that I am even using 1W.
YEP! And very often well under 1 watt of power. My typical listening levels are C-weighted SPL of 65-75 db with occasional peaks to mid 80s. In reality (Seated 10 feet from my 94 db sensitivity speakers) using small fractions of a single watt. Even with the rare listening at higher levels (Peaks 90-94 db) no sense of strain. However I want to preserve my hearing as best I can.🙂
