It is refreshing to see these types of articles. Of all disciplines of human interests and hobbies, Audiophiles are one of the most stubborn, misinformed, anecdotal and delusional bunch. Of course I am generalizing, but every time I engage in a discussion about audio quality, it is a losing battle. Not because of lack of data or supporting evidence, but because of the fundamental dissent for data driven arguments. Yo…

Of course they’re anecdotal - listening to music is a subjective experience. If someone really thinks their music sounds better after adding $100 cable lifters and taping $50 bags of rocks to their $10,000 system, they are automatically correct . Their ears, their hobby. It would be like saying that something can’t work because it’s a placebo - even if all they’re getting is a sugar pill, if the symptoms went away, t…

Much of this is cultural driven by a historical time when we didn't have the tools to measure this stuff, and reproduction was so bad that nearly anything that changed the sound in any way could be argued to be an improvement. Those days are long gone, but the culture remains. Getting good sound out of an old victrola--which were very expensive--truly is an art. Getting passable sound out of today's average off-the-s…

Wait, what? The “volume” of MIDI? I’m guessing they’re not referring to cc#7...? (Also, I’ve never encountered a 9-pin MIDI connector. 5-pin maybe?)

The majority of all active speakers produced nowadays are Class-D, it's nothing really new (and the fact they are super cheap). No idea how this guy wrote this article and didn't come across DIY Audio (or he just didn't mention it in the article). There is a tonne of information here: https://www.diyaudio.com/forums/class-d/

If your listening needs don't involve more than 10-20 watts, inexpensive Class-D amps can sound really good through a pair of good speakers . And because of their efficiency, an external power supply only needs a handful of amps (much lighter). Win-win for me.
