I don't think that Hi Fi, Mid Fi or Low Fi can be defined in a way that very many would agree, but since I've seen it referenced several times I figured I'd ask what it means to different people. I hadn't really considered that my speakers were anything but Hi Fi, but after seeing what level of gear is available they just might fit the bill.
I guess I might consider my Focal Chorus series speakers Mid Fi because they are technically a "budget" line of speakers.
Also, it might be reasonable to consider Mid Fi to be having a home theater receiver rather than a dedicated two channel amplifier.
