This is all great discussion but doesn’t it come down to your ears, budget and preference for the love of music. Budget and listening preference will ultimately be the deciding factor. If person A has a budget of 50 - 60k he’s not looking at Class D period in of story. I went down the class D route a few years ago when I first purchased my Maggie’s and told I needed a amp with at least 300wpc. So I ended up buying an Audio Research DS450M monoblock amp that put out 600wpc into 4ohm load. At the time for 12k and looked like a pretty good way to go, but after a few years of trying to recreate the sound that made me fall in love with the Maggie’s I knew the amp was my problem. Could it play loud an emphatic- yes, did my Maggie’s produce an audible sound - yes, was it musical to my ears, I would say no. But again that’s preference. I was mislead by dealer and the internet that led me to believe that Maggie’s required brut power it wasn’t until I decided to let my ears be the judge and bought a class A amp that puts out a whopping 95wpc. I’m not saying class D is bad I’m just saying that for my system and listening preference I went class A.
