More power, more better when comparing apples to apples is pretty spot on. The best example of this I’ve ever heard is when I added a second Devialet to my system go from a 200 to a 400. It was an instant wow. Same technology all around, just more power.
But now I use a Luxman 590, 30w class A and will never go back.
The type of power seems to me to be way more important than the amount of power.
