I received the new ifi spdif purifier, and it is impressive:
It comes with the iPower power supply and a minitoslink to toslink adapter. You can use both the toslink and coaxial output simultaneously. My expectations were low. IFI advertises the purifier mainly for cheap media streamers and components like Chromecast, etc. In my case I have an Oppo 103 with custom linear power supply and ethernet streaming using fiber media converters to a soekris r2r dac, so I didn't think the purifier would do much. But I've been impressed with previous IFI products and Music Direct has a great return policy so why not.
Although the spdif purifier does not offer quite as dramatic an upgrade as the fiber media converters, it nevertheless raises overall performance up a notch. Mainly increased realism of the instruments, which I attribute to the reclocking. For other folks who don't already have a lot of isolation/linear power setups, I would not be surprised if they experienced even better results. Someone at CA had positive review for their Bryston gear, so don't let ifi's marketing to cheap end mislead you.
Definitely worth trying for the $180.
