HiFi vs MidFi


I’m a relative noob to the audiophile scene, having just invested in an integrated amp and upscale (for me) speakers.  From time to time, I hear the term “MidFi” for some components.  Is there an objective or just largely accepted definition for this term?  I’d be curious to hear feedback on what constitutes HiFi vs. MidFi across various components.

Take the world finest amps/digital (Jadis' $$$$$$$$$ DACs/Drives) /Phonos /linestage/preamps. 
Hook  these components to any midfi speaker,,take your pick...and what ya got?
Midfi sound.
Now take a  super HIFI (like I have) speaker and hook it up to a  Sony system, cd player/receiver, and ya got hifi.
I've tested this out folks. 
Not saying nuances in the all jadis system are not there,, indeed there are stunning nuances. 
but the real hifidelity is inside the speakers. 
No 2 speakers sound alike, All tube amps, pretty much sound the same to my ears.

And the acoustic control of a room count for nothing?

All tube amp sound the same? Ridiculous... an Atmasphere tube amplifier, a garage 1217 tube amplifier and a Berning ZOTL are the same for your ears?

No gear sound the same at all.... Be it speakers, dac, amplifiers...

Acoustic treatment and control designed for a specific speakers/system are the way to hifi....Not the gear in itself by itself alone....Electrical and mechanical controls are also mandatory...

Pick the speaker you want and associate it with the right gear and put it in a controlled room designed specifically for it and you will have Hi-FI...

Obsession with speakers or any type of gear is only that, obsession... This is right if you are an audio engineer this is called passion.... But to reach hi-fi we must know elementary acoustic and elementary mechanical and electrical facts for a rightful embeddings of the gear /system we choose...

There is no best amplifier, or best dac or best speakers.... Only different needs and trade-off....
Fidelity's definition is faithfulness to a cause by continued loyalty. No matter what level of fidelity you are at, if you do it for the music, you are on the right track.

when i scan replies to a given post, there are some usernames -- once i see them, i simply keep the page scrolling right past the jibberish, don’t even read em anymore

remember the old dilbert comic strips? "blah blah blah blah blah blah room treatment" ... and so on

good for our sanity and positive attitude to treat those similarly, i think  🙉
