Hello Francesco
It's good to hear you like your 1500. I suspect you don't see a lot of talk about it because most of those here have either a KN 2000, 3000, 5000 or 6000. But I believe your keyboard would be similar (though less features) than one of these models.
This group seems to have gone on vacation for the summer. For some reason, no one is talking about any Technics stuff lately. Too bad, too - I always like to hear what other's are thinking about.
Tom
