We're getting into the weeds, but just so you know an amplifier can be both minimalist and reliable. But 'minimally engineered' is a different thingMinimally engineered (or as I prefer to call it, badly engineered) amplifiers lack unconditional stability, short circuit and other protection, and whilst may operate OK under controlled circumstances, are flaky and unreliable. Properly engineered amplifiers will stand reasonable abuse and be long-term reliable.
Sadly certain 'boutique' manufacturers make a feature of how fussy their Amps are to create a mystique to cover the lack of proper engineering.
I don’t see the hifi industry any more of a fraud than any other. Sure plenty of dirtbags, but that’s 10% of the population in general. And as far as adding some credibility back to reviewers, we are back to that 10% again. Also , applying exacting science to something subjective is a fraud in itself.
Well, I'll agree that feedback loops to increase gain are a non-starter, with few exceptions.Nelson is a perfect example of minimalist engineering, and it’s seems to be common knowledge that feedback loops to increase gain and hifi typically don’t mix. More so in Phono stages but in general as well.

So, you gave away your 2000+ dollars for a very questionable product from this company for example:I've been on these forums for quite a while, and while I don't believe everything that is being said here, I'm constantly catching myself believing in the fraud.
Case and point - I spent well over $2000CAD on a Pre-amp (with >$500 on tubes for a Freya+) and a Denafrips Ares II, think that I will have an amazing setup with these two items. I've been listening to them for over a year now and I consider them to be great.
Lo and behold, I decided to buy a SMSL DO200, for around $399 in the last 11.11 sale, and plugged it in. Immediately, I heard a lot worse sound, lack of bass and something's wrong with my speakers. Thinking to myself ah ha! I’ve made the right purchase decisions.
I then realized I had wired the left and rights wrong, so I fixed it and what a surprise, everything returned. More deeper bass (if you see my other thread about lack of bass with my R11's), room shaking response, a sense of excitement that was sorely lacking in the Denafrips and Freya combo, and just a sheer sense of "speed". Drums felt like they hit me with force, whereas in the previous setup they were dulled a bit. Although we are talking 99.9 vs 99.8 difference. The price difference is almost $2500 vs $399.
The more and more I realize, maybe this industry is just a load of fraud? Even using my wife as a test, she likes the SMSL far better (her hearing range is far better than mine actually, she can hear things I cannot, like small high pitched sounds in the music here and there).
TL/DR - basically, I spent $$$ on equipment that did nothing but burn money, all replaced by a $399 DAC that does it all. I'm also using mono LA90's which are amazing as well.
My question is - is the rest of the audio industry just full of it?
Feedback, if negative, decreases gain of the amplifier. Positive feedback would increase the gain and the chance of instability. Bootstrapping a driver stage would be an example of that.Well, I'll agree that feedback loops to increase gain are a non-starter, with few exceptions.
BTW, Mr. Pass does indeed use feedback. My J2 has about 20dB of global feedback.
