if I remember correctly the technical specs are quite the same - but I did not have a chance to listen to both of them; I thinks the main improvement was about saving energy (hello EU!)
how much do you get the 8000 off? I bought mine 50% off - so if somethings breaks tue to age I have a little amount get them repaired...we are talking about technical products which WILL fail one day so if the price reduction of the old ones is only a little off I would prefer the 8002...
