Reference my post earlier regarding Ifi iUSB, I can confirm that with the Gemini Cable and Purifier, it makes a substantial difference. Plenty of reviews etc... out there, it's more money I know but it really does make a difference.
I believe it that a cleaned up, or removed power from the usb would benefit the digital signal from interference.
So I am interested in trying this on my HA-1..
BUT..
From what I have observed,
The "IFI Gemini Usb Cable" is actually redundant(!)...
as the "IFI - MICRO iUSB POWER SUPPLY" does the same thing(removing usb power),
While also replacing it with a separate power supply that they like to give special hyperbole descriptive names to...
To state that both solutions sound better together, means the one is not doing its job of isolating the source usb power, as that is the only thing they perform in common.
So if you like to have a clean USB,
Do you need to get BOTH the wire AND the power supply?..
For $200 each? (!)...
Why do that?..
Why spend about $400? For both??...
When you have an actual BETTER solution for just $100..!!!
What's the schiit I state?
The "WYRD USB DECRAPIFIER"
From schiit is arguably BETTER than BOTH (!)...
How?
Not only does it separate and add it's own power supply to the line,
But ALSO has a USB repeater to "regenerate" the digital signal
ALSO you can use your own preferred USB cables instead of some forced use of a "Gemini Cable"....
Will common sense prevail?
Up to you!
