Good point. I think it’s not been said enough that just having power doesn’t equates good sound. Barring inefficient planars like the he6/sus etc, it should not be the main criteria for an amp purchase especially for dynamic driver headphones. I’ve ran my starlett with planars like arya, rad0 etc with great results despite having measly power output by today’s standard.
2W is plenty for most headphones out there and I’m glad to see more manufacturers coming out with less powerful amp focusing more on quality transformers and implementation. One amp I would like to hear in the future is the Ampsandsound ovation and that is peanuts compared the 2W your wa23 produces.
