There are physical differences in that normally high end gear is better built and uses better components both internal and external.They weigh more, for example i own a dvd player that most people would consider high end and when you pick it up it weighs over 30 pounds, has amazing sound and is the first dvd player that i have heard that could qualify as a high end cd player.It like many high end products is short on features but high on picture and sound quality and it is built in Canada.
Mr.p is right however you need to go out and experience it for yourself, seek out a high end store, us music lovers are friendly folks.
