"What we really need are amplifiers with variable gain stages."
Yup.
I know there's been a few done but I have no idea how well. I vaguely recall PS audio had products with what they called a "gain cell" or something like that but I've never heard one.
As far as I know the "standard" for home audio has always been 1V for line-level interconnects so I was surprised when CD players were 2V. Marketing in action I suppose. IT'S NEW, IMPROVED, 6dB more fun right out of the box!
There's a lot to be said for deliberately mis-matching impedances from a design and compatibility standpoint but I've been toying with the idea of building a chain focused on preserving as much signal energy as possible all the way through. Probably won't make much difference but might be a fun thing to tinker with.
