I think these are bad rumors circulating again. I was told that they are made in the factory, using extra wood from making the other harps, and using one piece rather than laminated layers.
I tried them all and they all sounded good. There were no duds or exceptional instruments. They may need more time to age than fancier models, but they sound good to begin with. They are simpler looking than the carved models, and that seems to be the main difference. Their construction is more like a regular harp than the 85 line.
