I'm not sure how deep your qualifications have to go to say, "The workmanship simply appears to be quick, sloppy, potentially unreliable and possibly unsafe for the reasons Braillediver described." But for the record, I am not an amp maker, but a hobby builder of pulse width modulators, stepper motor speed controls, LED flashlights, and telescope control systems.
My core argument from the beginning (speaking from my marketing background) has been that the internal photos of the amp do not inspire confidence in Singlepower's products, at least for me and a few others here on the forums. Rather, they raise concerns about quality and perceived value--things I know a little more about. My point has been that when your product looks sloppy, random, fragile, and possibly even dangerous, it matters little if it is actually otherwise. It is what the customer or potential customer thinks. I'm fully qualified to assume that role, as is anyone else.
But before I go (again), let me say that the almost single-voiced defense of Singlepower products by owners of its products, Mikhail's demonstated iron-clad satisfaction guarantee, the numerous reports saying these amps sound truly awesome (especially at their price points), the fact I can only uncover one report where a connection failed, the lack of solid proof these don't meet Class A specifications, and the simple fact that they are darn good looking on the outside has me reconsidering my less measured knee-jerk disgust at seeing the amateurish-looking insides.
In other words, I think I may eventually go through with my plans to purchase a Singlepower for my own use. I'm a sucker for value and agree to a large degree that it is the sound that matters. As a potential future customer, it would be even better if Singlepower responds to the concerns voiced here on this forum and cleans up the insides of their amps. And that has been the whole point, has it not?
And now, in the spirit of trying to inject more humor into this thread, please identify Singlepower's signature point-to-point wiring from the following photos:A - B - C - D -
