i will be sending my ref 9s in for the se upgrade, to me its a easy choice, if you don't like the nuforce sound go and buy something else, and post on their web site your thoughts, and leave this one to the people who bought nuforce products and like them, i work in the behind the seens world and know what goes on with electrical and machanical operations, where most people have no idea, its magic to them a/c, elevators, cars, heck just fliping a light switch, in this real world all is not perfect, but we try to make it as perfect as possible, like in the case of the reviewed ref 9se, yes its going through changes for the better, it was not for sale but was early production models, the review really sold me on the upgrade as well as johns info, hopefully i can plan to have it done while on vacation so i wont miss any music time at home, jason if you read this maybe you can give some info on the turnaround time for the upgrade of the ref 9 to se status,
