I love that they actively seek input from the community, respond, and then implement based on feedback. Then they offer a nice discount to early backers. The request to switch to the Sabre was one such implementation.
On top of that, they have a very competent engineer designing the product, that basically helped write the USB specification, and helped create a world class DAC. It makes for a very compelling product that I believe will succeed and sound fantastic, at a lower price than most competing products.
In essence, and in reality, we are all "investors" to the project, so we all want it to succeed as well. It's a great campaign.
