I used Sea Change to test the i5. This unit reminds me a lot of that device, but with improved Android capabilities it would seem. It is passing the Miles Davis Kind of Blue test very nicely. I may be dropping this Chord Mojo concept I have been keeping in the back of my mind. This unit seems to do the trick so far. Now we need to see how it handles streaming sources like Sirius XM and the Synology server before coming to a final conclusion but so far; so great. Nice silent background with the FLC8S for people concerned about hiss issues in general. Nothing specific to Cayin implied, some people just worry about hiss and appropriately so.
