I saw a youtube of the Chieftains with the great Derek Bell ( see http://www.youtube.com/watch?v=WQd51OItvTU&feature=related ) and noticed his playing position. There’s a good long look at about 1:40 on the linked video.
His harp is medium-sized, and he has it standing on the floor, with the kneeblock at the level of his chest.
I’ve been taught to set a harp up (with harp feet, etc.) so that the kneeblock is about at ear level.
Now I’m just a beginner and who am I to question the great Derek Bell — but can you tell me more about that? Where’s your kneeblock?
