depending on the music and how was mastered sitting at tweeter level can make it more or less enjoyable....sure it meant to be at tweeter level all else being equal but the synergy of the rest of the room affects that too.
I found the synergy of moving to a koetsu rosewood platinum cartridge made a profound improvement to how music is portrayed in my system and made it less sensitive to seat position or the mastering of the record....the koetsu just makes music sound right (even if not great mastering)....no product is perfect though as the koetsu is more finicky to records that are poorly pressed or manufactured
