It's now in the unused USB port of my JCAT USB card. Although subtle I didn't like what the Jitterbug did inline. It's hard to describe exactly how but it seemed to decrease sound quality which mainly resulted in a loss of clarity or a very subtle increase of distortion, mainly in the highs.
Will listen with the Jitterbug in it's new position till I feel like it doesn't add anything or, worse, detracts from enjoying music.
hi,
JCAT usb card is newly constructed for USB audio. Jitterbug is just one more handicap in the chain. I don't think it is doing any good in the inline chain.
The main problem is in USB POWER line of 5V. It can be dirty, but it is hard to filtrate it after it leaves the computer USB port. In my five years, dealing with USB audio, I found that the best solution is to use so called "Y" or "V" USB cable. Data pair wires are plugged into the computer USB and power line pair is connected into the very good quality linear 5V power supply, and than both of them into the Devialet USB port. This way you don't need to use JCAT card any more.
For my taste the sound was better with computer USB port and external 5V PS than with JCAT USB. So, I'have sold mine JCAT.
This is not an advertisement, just to get some idea what I meant to say :

ofcourse after five years I DIY my silver cable and power supply according to my tastes.
