Are future improvements in Amp/PreAmps slowing to a crawl?

Interesting thought, it basically wrong and right.  Yes, the circuit topologies commonly used are reaching a limit in refinement. No, there are other topologies that we are just exploring that are proving better.  I and others have heard them, some now posses products based on these new topologies.  They are groundbreaking but they are a new wave of doing things in a world habituated to the old way.

But only time will tell, and it is telling as listeners discover it.

Morphic fields!?!?!? I've been poking around physics for a while now but I've never come across Morphic fields. Sounds like you listen to lots of Coast to Coast AM. In the world of reality we call crap like that pseudoscience. State vector collapse within the framework of the Copenhagen Interpretation certainly doesn't call for magical Morphic fields, and that's the cornerstone concept concerning the observer's relationship with the universe. 

The M-field idea was relevant in biology when it was proposed. Not physics. It’s actually a good idea that wasn’t developed in the right direction and its current incarnation is somewhat laughable, mostly because the new agers broke it. They do that with everything

That's actually not true. Sheldrake would be the first to say Morphic fields apply to everything, animate and inanimate, from birds to fish to electrons to trees to words and symbols. Now, we can do this the hard way or the fun way. 😄

Oh... So it's pseudo-meta-physics!
