Well, Vince........
I have built amps using several of the new self-oscillating amps modules. I have also heard some of the competing brands using the same modules.
Maybe because I have spent 20+ years trying to build conventional amps, that I am more tuned to the differences between them. I built open-loop designs, and they are perhaps more prone to revealing minute changes in power supply design.
As for the Class D ones........
They seem less prone to power supply changes. While the guys who design the modules are all convinced that theirs is better than the next guys, my beta testers say something else.
Yes, they can tell A (module) is different than B (module). Although, press them to say which they prefer, and they all come up blank.
For conventional amps, it is usually easy: "This one has more bottom end and dynamics. I want this one." You do not hear that much difference between the various Class D modules in that regard, so it makes it harder for them to chose.
If I am not mistaken.........you probably have speakers with a very low impedance. Could be that what you use mates up
better than with other amps that you have tried.
Personally, I am not fond of a certain brand into low-Z loads. There is too much interaction between the load and the output LPF. There are other brands that claim to have solved this problem. Ask me in about a month or two: I should know by then.
