The three levels of "fi" you list is sheer genius. (just an elbow in the ribs for some holiday fun). Peace to all.
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.
