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.

I’m thinking of starting a go fund me page for tubebuffer. Maybe with some help,we can improve his quality of life. No one should have to suffer like that.

Where you stand on this, depends upon where you sit..

Seems like a term made up for insulting others. I bet there are many so-called mid-Fi systems that some enjoy more than those who buy to impress their friends.
