Describe the "new HiFi sound"?

Recently had a discussion with an audio friend over the word "musical" and what this word means to each of us with regard to sound from different amplifiers and speakers. Some debate too.  And, reading this other comment on Agon once in a while...how some equipment has the "new HiFi sound".  

ASK: 

Can someone describe this, in your words, what is the new HiFi Sound to you?  Examples? Or, opposites of the new HiFi sound, what does this sound like?
