Is it worth adding a Schiit Audio Eitr?

I can't recommend the Eitr highly enough.  I moved from  Curious/W4S Recovery USB decrappification setup - adding the Eitr changed everything for me, and most others who've bought one.  My bet is you'd be letting your Regen go pretty quickly.

You would be better off putting in the USB Gen 5 upgrade board to determine if you need the ISO Regen etc.
I agree. So sick of all these decrapifier boxes the last 2 years and cost I'm going to add the board to the Yiigdrasil.

+1 on avoiding gizmos. The N100H may not need them and can be better without as it was with my N100H/Exogal Comet Plus combo. The ISO Regen/LPS actually degraded the sound quality.

Replaced a MF V-Link 192 USB/SPDIF converter with Schiit Eitr. It's installed between an Aires Mini and non-USB Gungnir w/MB upgrade. I didn’t have a noise issue with the V-Link so no change there but the Eitr did improve SQ slightly. When I went back to try the V-Link, I noticed a reduction in image precision and stage depth; the music presentation flattened somewhat. For $179, the Eitr was worth it to me. Of course, it necessitates a digital coax cable from Eitr to Gungnir that the Gen 5 upgrade direct to your DAC would eliminate.

IIRC, Schitt has a stmt on their web site the newer upgraded DACs do not need the Eitrr - why not ask them?

but you can try it and return it for a tiny fee

I bought an Eitr in August for my car stereo. I tested it in my “big rig” and never took it out. I have planar speakers that typically do not have pinpoinf imaging. With the Eitr, the instruments were in tight focus. Some of my recordings now sounded like they were in mono, until instruments abruptly appear past the loudspeakers. Music is now more realistic and natural sounding. Highly recommended!

Thank you for the feedback.  I like the idea of having fewer than more devices in my signal path, but I may just try the Eitr because I don't feel like shipping out my Gumby again and if I'm not blown away I can send it back.  Easy right.  

I believe this is just a board upgrade/ swap for you... not sure why you wouldn't go that route  vs adding yet another cable into the signal path?

PS.. I've just ordered an Eitr since I have to use an external with the first generation Metrum Octave. I go thru a new asynch converter each year as they keep improving, used a Gustard U12 with Aries mini, then found the iFi Nano to be a better match when I switched to Sonore microRendu (same chipset as U12 but battery vs AC mains power)
