Pros: Small, feature-laden, jitter measures LOWER than advertised, sound improvement was significant.
Cons: You can buy the Audiophilleo 2 for almost half the price if you don't need the features and get the same sound quality.

They also allowed older DACs without USB to be used directly from a computer in a manner that improved over the usually low-quality optical or coax S/PDIF outputs available. I scratched my head for a long time over whether to buy a Halide Bridge or something from Empirical Audio. While I pondered what to get,...(read more)
