Loyalty can be caused by many things. I was a Technics fan (hence the name) since the AX-7..with KN5000 as my favorite..I immediately regretted it the moment I sold it when I got the KN6000..especially because the KN6000 came damaged (parents hand carried it away and somebody dropped a bag in the middle of it breaking about five keys and damaging the internals...I tried to repair it, but the composer kept lagging..) I so loved the user friendliness of KN5000 particularly the composer...I would take that composer's friendliness over all the pretentious complicated stuff we have today. Many years ago, I brought my 5000 to a studio in Oregon and when the guy played me five chords on his guitar and put me on a hot seat "Show me what you can do". I whipped up a song in maybe about five minutes tops. Got a deal to be a recording keyboardist for a couple of his songs on the spot. I haven't found any thing that comes close to my KN's user friendliness till today, and (you can call it an excuse) that definitely is one of the major reason why I played less and less..I briefly got back in with Korg Triton but that was not the same, until I finally stopped playing in 2010 (except when needed like funeral, family party, etc). But yeah, I was loyal because I felt it gave me what I need no fuss no muss. Last year I managed to get a 2600 (5000 is impossible to find), but it was not the same, the sounds definitely sounded outdated and the touch was horrible...I guess you could say I was loyal to the KN5000 not Technics...(haven't tried the 7000 though).
