Well, it seems no matter how hard I try, I am never able to get anyone to think outside the box here. Sort of frustrating.

For instance the gold plated metal film Holco resistors a few year back were very good and then the quality went down and down and down. I know a few products hat used Holco at critical location and those products from 1007 and 2007 are so different in sound that you would never believe that they are the same products.
Well, this would be a great opportunity, actually. I don't care about finding a great brand resistor, you see. But the learning is great. We can ask: what applications were these used in? How did the "quality" decline: what physical and electrical characteristics were different. The in the context of the topology, we have learned something.

I have heard no one offering help, only saying "it's impossible." Oh well. It is correct that a person lots of amplifiers every day for many years would have some experience. BUT, I also hoped a lot of people building a few amplifiers each could all get together and accumulate a similar amount of data.

However, if no one is willing to think about it this way or participate, the idea of a collaboration to build a database is a dead issue, I guess. I cannot do it alone.
