Is it worth adding a Schiit Audio Eitr?


I've got an Aurender N100H running to a Schiit Audio Gumby (Gen 2 USB, not the Gen 5) via a Curious Cable and the ISO REGEN powered by the Ultracap LPS-1.  I truly enjoy the soundstage provided by this setup, but I still have a bit more noise than I had when I was using a digital input via digital coax.  Would the Schiit Eitr help to lower the noise floor further.  Does it make sense to add it to the signal path?

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)
