Audioquest Jitterbug - snake oil or upgrade

[britain4]

Just so happens I got a Jitterbug for my birthday this morning - a quick A-B listening comparison through my Grados reveals a very nice albeit subtle improvement to soundstaging, deatail and it's tightened up the bass just a smidge. It's a subtle one but worth the money in my opinion. I should say this is with the original Dragonfly 1.0, hope to upgrade to a Red soon, and we'll see if it brings similar improvements there.
