Ray, I did some style downloads from the PR903 to the KN7K some years back and had no problems loading and playing the files. I think there were only four or five different styles with two of us comparing the styles back and forth until we found the new ones. I can't quite remember what the problem was, even though a Technics rep told us they weren't interchangable, but it seems the KN7K styles wouldn't load and play in the PR903. Different sound engine? Anyway, the amount of time spent on doing all that work just wasn't worth the end result. It's like upconverting old KN styles where we had to use a hex editor to change the header codes. Just a lot of time and effort that didn't always work out. Anyway, never say never - until technicsplayer says it can't be done! Have a great New Year!!
