978-998......Does SEEM like a train going nowhere with limited information on these processors.However having the 990 for some years now and never being disappointed with it's performance I will still hold out at least till the first quarter of the new year.From my recollection that is the time when the 978 will raise it's head. That's when I will take my shot.
Room correction is important however using my Radio Shack SPL meter I see no reason to step up to the 998 just for room correction.
EARS...seem to be the best tools.
At least it my understanding that one will have room correction and one will not. If that is not the difference I stand corrected and that is another reason for peoples' frustration about the lack of information.
