Jitterbugs from Audioquest and the Regen

Ok, I now have 2 Regens, 2 Audioquest Jitterbugs and a Schiit Wyrd.

The Regens are powered by a Linear power supply with a y adapter and are using the USB hard adapter.
While the Schiit Wyrd is using a .5 Pangea AG USB and is then plugged into the first Regen.

I'll give them a few days with them together before I provide my impressions.

Here is my conclusion with the Schiit Wyrd, Regen, and the Jitterbugs in my system.

First off, I tried every single configurations with these units.
The 2 Regens plugged together using the hard USB connection and the 2 Jitterbugs plugged into my Bryston BDP-2 provided the best overall sound quality. And boy does it sound great! Very deep soundstage, but also very natural sounding throughout.
Funny, I found out with all the gyrations that I made, was that my linear power that I use to power the Regens is sensitive to power cords. I ended up using a Mad Scientist power cord that was plugged into a Bybee power purifier.

The Schiit Wyrd just wasn't as good as the Regens or perhaps it just wasn't synergistic with the Regens. Every time the Wyrd was in the chain the soundstage became out of focus. Vocals that were centered became all over the left, center, and right.

I even tried the Wyrd in front of my external hard drive and I still didn't like the result.
So, the Wyrd goes back for a refund. I would have kept it if it showed it's worth somewhere in my system.

I have been using an iPurifier for almost two years. I remember when I first tried it, I immediately noticed an improvement in musicality that made it easier to listen to computer audio via usb. I recently received a Jitterbug and placed it in an unused usb port on my Mac. The music was clearer but there was a slight but perceptible loss of loudness and bass. Then I tried the jitterbug alone between my Mac and usb cable (i.e. no iPurifier at the dac end of the usb cable) and the sound opened up, the stage was noticeably deeper, and more detail became apparent. There still may be some shortfall in bass but I'm not sure about this yet. There was no change in loudness so that would appear to be due to the combination of the two devices. Very different from the iFI iPurifier which now sounds like it is filtering a little more than it should. I have not tried the Jitterbug and the iPurifier together on opposite ends of the usb cable though. Btw, Audioquest does not recommend doing this. I ordered a second jitterbug just to see what affect, if any, it may have when used in an open usb port on my mac with the first jitterbug on the usb cable. I have not tried the Regen. I refuse to go crazy with all kinds of band aids for usb audio. Think I am at the point where it's just not worth it. I'd rather futz with my turntable.

Ozzy et al - had the Jitterbug a couple of nights now...maybe 16 hrs or so on it. Have to say, so far, I'm not hearing any improvement with it. Set up is exactly as described in my 8/15 post above. Will give it some more time before deciding whether or not to return it to Music Direct - but out of the box, "nada". I should comment that I don't leave it plugged into the MBA 24/7. I put it in when I'm going to listen to music with headphones. Headphone listening can go 2-3 hours. Glad for all for whom it works.

Just an update.
I had the iFi Purifier and the iFi USB power supply.
I found that they did not work well with the Regen.

To me the Regen is the best overall improvement for Audio. Adding another Regen adds another layer of depth. And then adding the Jitterbugs improved upon that.

I have also noticed an improvement in my UHD 85" Samsung with a couple of the Jitterbugs installed in the open USB's.
The picture becomes even more 3D like.
