That's why I (and Mrs L) have experienced the following in our 15+ years of her politely supporting my 'hobby'
>> play a well known CD on the target new item (speaker, player, whatever)
>> hear something you never heard before and go "Wow!!"...enjoy it immensely.
>> Go home and check the same CD on the existing kit and, guess what, hear that same thing you never heard before.
Why ? Probably as suggested above, once heard you can't un-hear. The brain knows it's there and fills in. It is then all about the ease by which we hear it and that's the big bit about ears/brain/perception/fatigue.
For me, it doesn't take anything away from enjoying the experience by understanding it a little better. It probably makes us a little wiser in the demo scenario.
George, get that demo organised asap !!!
