??? Where Does "High End" Start ???

 There are terms we in this hobby use to describe certain characteristics of the components or sound evoked...Without fail,the terms entry level,mid-fi & high end will show up in component reviews or conversations regarding equipment components...
 So exactly how do we define these terms in absolutes?I understand there are components that,in this day & age,outperform their asking price in orders of magnitude but even if they do,they will invariably be tagged as entry level,mid-fi or high end simply based on their asking price..
 Assuming entry level starts at say $500.00 per component,where does that end & mid-fi start,$2500.00 per component,$3500.00,$4500.00,$5000.00?
 How far does that pricing structure go until you consider a component to be "high end"?
