That could be a number of things such as placement , room acoustics or could be entirely true , what I am talking about is putting all the players side by side and really testing them which u can't do with id companies which is a turn off for me among other things such as crazy bs claims like these are as good as these and so on . I'm going to try and find some one in my area with 800 or 500 and listen for my self , but even that is hard to compare given different rooms and equipment etc
