Tubes vs Solid State - Imaging, Soundstaging, 3D

I think the sonic benefits of NF is pretty well documented and understood as are the drawbacks (nothings perfect).

The fact that it is so widely applied would seem to speak for itself in terms of overall merit.

No NFB would seem to be the exception, not the rule. Those who buy into those benefits versus drawbacks have fewer options to choose from.

That's pretty much how these things work. Any product that is successful over time offers unique benefits.

One must also always keep in mind that there is a difference between theory and application. Theory is well, theoretical. Means nothing until realized in something in the real world you can touch , see, listen to, etc. That's what matters.

In my mind, the things that go into good sound are well documented and understood, especially by the "experts". Why re-hash here? Any assessment here is bound to be incomplete and flawed and affected by biases.

I've heard one of Ralph's amps at a show once with the big CAR speakers. It sounded very good. SO did other's at the show. Each had advantages/disadvantages beyond just sound quality. THings like cost, size, aesthetics, and other more subtle differences in features.

All that stuff matters. A lot of sound quality discussions are mostly about cutting hairs compared to the bigger things that the evidence clearly indicates matters to most.

"Techno babbalo obfuscaturo a mundo. El tubo harmonico supremo."

Eat Oreos. It'll all sound muy bien.

Few things are ever "universally" realized.

Does not make sense to me that such things would be ignored by the experts whose products can benefit.

Its all about the dollar. People often purchase audio gear with their eyes rather than their ears. Then once they are saddled with it they have to justify why so they can feel good about it. Its much easier to design with feedback than without. In the case of amplifiers, the use of feedback is common as it is part of a standard of how the speaker is driven. But the standard ignores human hearing/perceptual rules. I am sure many have seen this link before but here it is again:

In a nutshell the more your equipment obeys human hearing/perceptual rules the better it will sound, the involving it will be and the less likely that it will wind up in a closet or being resold. But if you are only interested in how good the equipment looks on paper you might think global NFB is a good thing.

"But if you are only interested in how good the equipment looks on paper you might think global NFB is a good thing. "

Its an old beaten topic, but actually I think most people, especially audiophiles, are more interested in how something sounds, not how it specs out on paper.

I suppose if its true we have all been brainwashed, or earwashed I suppose as it were (I could probably use on of those) we don't really know that most of our stuff does not sound as good as it might if we would just go with the gear that caters to our ears the best.
