What does "Sounds too Hifi" mean???


Lately I've been reading this phrase on various forums, and have no idea what they are talking about. What is the "hifi" sound? What does it mean when something "sounds too hifi"? Does that mean it doesn't dissappear, that you are aware that the music is being made by "equipment"? Is this term in the audio glossary?!!!

With psychic power and primal intensity,
sound too HiFi means you will feel fatique after long time listening. you will notice about this.

take your time to test.
hi fidelity or hi fi is a good thing....a lot of hi end audio is overly analytical...at a music venue bass is fast and loose(when did you ever hear an acoustic or electric bass that was tight?) and a horn players' runs will make your hair curl....too much of hi end isn't like listening to live music at all....hell,even anne murray is loud in concert.
...it's when you don't know how to describe precisely or more specific or haven't enough vocabulary or combination of all above you can say instead: "HiFi", "NotHiFi", "NotTooHiFi" and "TooHiFi"...
accentuated highs & boomy bass is sometimes associated with that vernacular "too hi fi" when compared to a more desirable flat response
