YES I have it. very very well made. great materials and emf isolation.  works well with
their usb power station, which it is was developed for.  is it worth it?  if you are using a usb
dac that doesn't have power from an external source, YES. the cable delivers external battery
pack power to the dac, eg. i used an Apogee Groove with my iPad and the cable made the ipad
not refuse the groove like it did before when connected to an external 1300 amp battery pack.
 
for other applications,?? you decide...but a thoughtfully executed and designed and made product!

How are you finding the Groove? Is the sound quality improved when using battery power?
