^^ The pair that I auditioned were sold months ago. Ironically, I could have bought them at the time. I think I wait and see what happens with the oppo. My reservation is buying a revision #1 hp from a company that has not been in the hp game (correct me if I'm wrong about this).
You're right--this is a first generation product. Definitely something to consider. I like long warranties, like 3 years from Audeze and 5 years for major Schiit. I wouldn't buy a new product with a 1 year warranty.
