I, too, have followed this company for years, and bought a pair of Callistos just a few months ago. Roy claims even the Eos I will outperform the Callistos, which would be mind-blowing as the Callistos are absolutely amazing. Plus, Roy is a great guy.
I guess I should add this, too. Generally, I'd be irritated with buying a product, then having it discontinued and having it replaced by a better product at a lower price. However, I enjoy my Callistos so much that, honestly, I have a hard time believing that Roy is able to do this (and at this point, I'm so satisfied that I don't have an itch to upgrade). Roy hasn't steered me wrong yet, so I'm excited to check out his new offerings.
