Audioquest Jitterbug USB Filter
The USB connection has become much more widely adopted in audiophile circles with the recent acceptance of the computer as a high quality music source.
It is true that computers can deliver audio with much greater resolution than many traditional hi-fi components but as with all things they have their particular drawbacks. With computer devices in general it is often the issue of radio interference and electrical noise generated by power supplies in particular that spoils the party.
This is why Jitterbug was created. By placing a Jitterbug between computer USB interfaces whether between memory device and PC or PC to DAC to name but two the RF and EM interference is carefully removed. This allows a more stable transfer of data packets which in turn yields a less two dimensional sound with much greater warmth and realism. It only takes a couple of seconds to install one so why not give it a try?
