Look, guys, manufacturers design PA amps with very specific applications in mind, such operation in public settings and open spaces. They don't do this to be different. They do it because it allows them to design and build a product that fits it's designed purpose without having to worry about achieving SOTA, or even good results, in areas where it isn't needed.
As you move from a public space to the average home, the importance of certain performance parameters change. These include:
- High output. You no longer need hundreds of WPC because the distances are small and the ambient noise is low.
- Power efficiency. Home users aren't plugging into highly branched/taxed circuits of some old, hoary, dance hall. Home circuits are very conservatively arranged in order to be fool proof. Indeed, successive National Electrical Codes make it exceedingly difficult to overload modern home circuits.
- Strength in middle frequencies. Helps in getting the gist across iaw Fletcher/Munson, but the low noise of private homes allows, and indeed supports, critical listening. So linearity of FR becomes more important.
- Grounded gear is no longer critical because homes are classed as enclosed weatherproof structures. Double insulation is more than sufficient to meet electrical safety needs, especially since there is a much smaller risk of ground lifts (routinely used in PA because there isn't time to trace group loops) and moisture that can lead to electrocution in public settings.
@amirm's Test Results show a great deal of how the difference in design philosophy result in higher SINAD, lower SNR, and roll-off in FR for the PA amps he's tested. He, and people other than me, have talked about a variety of issues that make them less than ideal in most home settings. The manufacturer's even go so far as to talk about their designed purpose. These are real things, guys. It's displayed in black and white for us. So what is it about these issue that you're not getting?
Consciously ignoring test results, manufacturer warnings etc. to justify your own biases is one thing. Arguing with people who point out the obvious is another. Hence my original post on militant stupidity, which was not directed at anyone specific despite the now obvious fact that a few people are trying their utmost to display it.
