What defines mid-fi versus high-end?

Mid-Fi: Any component not worthy of being included in Jay's Audio Lab $500K system!

Nowadays, lots of so call low budget speakers, amps, cd players, turntables, etc that are very very good, that actually produce High Quality sound. What is High Fidelity? That is very subjective. Some of this so called hi-end stuff sounds like crap. To me, it is more fun seeking out the lower cost stuff that performs way above its price. A few examples would be, the Sphinx integrated, the wharfedale diamond 225’s, Elac b-6 (the original one), the music hall mmf-7, the Marantz cd players (take your pick), mine is the hd-cd1, Akg k550’s, Graham slee novo, Musical Fidelity v90 dac, audioquest type-4, etc etc etc...you are getting a good slice of the High Fidelity pie for not an insane amount of money. I mentioned just some components I have first hand knowledge of, those that I have heard. I'm sure there are many many more. 

I recently jumped back into audio and put a system together for under 1k.  Tekton Lore speakers,  Rega Brio integrated amp,  Schiit Modi dac via and older NAD dvd/cd player I already had.  Definitely not high-end but the combination works well and I’m not wanting for more.   Mid-fi fits me fine I guess. 

I'm going to link to a video presentation from Merrill Audio talking about his GaN amps.  To me it's about how he talks about audio that's  important.  Things like  he doesn't have a power switch because it affects the sound.

These are the intricacies that mid-fi just doesn't address.  As I said in the last time this was question was posted.  You'll know the difference between mid-fi and Hi-fi when you hear it.
