There's been a rising trend of new audiophiles who get all their information from bite-sized YouTube videos and thus don't know any of the exceptions to the basic rules.

IIRC, Andromeda bass drops by something ridiculous like 2 dB per ohm of impedance added. It's been documented and graphed, CA themselves recommend an IEMatch, and big-brain KB tuned at least the original while listening out of a Sony DAP with 1.5 ohm OI. It's nothing you can't simulate with a voltage divider like an IEMatch, EarBuddy, or UE Buffer Jack, though, so the $300 cables are still pretty pointless.
