Its performance improvement quotient is minimal at best (if at all) to nil, even with its own AQ mini-DAC stablemates, the AQ DRAGONFLY or AQ BEETLE.
I passed on the JITTERBUG in a head-to- head bake-off (in...out) with these mini-DACs
- as a secondary “filter” link with my high-end mobile cans with the DRAGONFLY; (just upgrading the cable was a better result) and
- also as a further added-in “filter” link with the BEETLE for my TV output via a top-end Toslink cable. The high-end glass Toslink cable swap-in was a better choice than the JITTERBUG again.
MY TAKE
Everything in this hobby is built to its pricepoint. The audio performance follows in lockstep. This is no pathway on the Yellow Brick Road to audio OZ.
