AQ JitterBug with high-end music server/streamer and high-end DAC?

The Jitterbug works well for me with a really bad source - my iPhone while connected to Apple Carplay in my VW.  Actually quite a nice improvement it makes there and I think I got it for $49.  I would never use it in a home hi-fi setup though.

I prefer ifi Audio iSilencer3 With iPurifier3 works well with Pangea USB Premier SE cable to Mac Book Pro

I attached a Jitterbug from a Seagate 8 TB HD into a Cambridge Audio 851N streamer and heard an immediate improvement.  The sound seemed warmer and less harsh.  I was not using an audiophile grade USB cable, so I'm not sure if that made a difference.  For my money, it was worth the $69, and added one to my car a short time later with satisfying results.

I've recently added the Audioquest Diamond USB 3.0 to the connection from the HD to the 851N and have not yet tried adding the Jitterbug.  I'm still reveling in the dramatic difference in the sound that the Diamond cable made to my system.

I tried the Jitterbug and it completely wrecked my sound.  It sucked all the life outta my recordings and I returned it.
