I just tried the Audioquest Jitterbug in my system between my ultrabook and Devialet. It seems to remove some grunge from the USB connection. Of more interest is that I feel that it has improved clarity a bit by dropping the noise floor some. Music seems to be more relaxed with much better pace and rhythm. On my system, it feels like almost analog-like. Not profound but easily noticeable.
Is anyone using the Jitterbug? Does 2 jitterbugs make a difference?
