USB noise filter, jitterbug or ifi

USB jitter reducing devices are not for reducing jitter from a memory stick to the DAC, but from a PC to a DAC.


The only other benefit, ground loop reduction, isn’t really an issue in an attached memory stick.

(1) Erik provided you wise advice.

(2) FWIW without prejudice to his comments in (1) above, I bought the AUDIOQUEST DRAGONFLY USB DAC to bypass the crap POS sound card in my laptop. Prior to buying it it, demoed both the AQ DRAGONFLY “Black” and “Red” models with the the AQ JITTERBUG .

MY TAKEAWAY:
(A) I found miniscule ( if any )  to nil improvement in audio reproduction with inserting the AQ JITTERBUG with either model of DRAGONFLY USB DAC.
(B) = I passed on the JITTERBUG.
