Can someone explain what the difference is in the NAD software upgrade version 2 from 1. My dealer has explained that it does not have that much impact on the performance but provides for certain bass mapping and programming capability such as renaming devices, ect.. The reason I ask is that I a considering the purchase of a 753 and I can purchase the old version for a lot less money. My dealer is willing to sell me either, but felt that I would be more than satisfied with earlier version.
the new version is the way to go as it suposedly fixed the hiss/hum issues check the other post on hiss hum issues, and later if you need to upgrade from version 1 to 2 you are looking to pay extra 150-200 so go for the new one.
