Innuos owners. Chime in

No problems with the app whatsoever. I use Nordost Brahma on my Zenith Mk3 with good results.

On USB Intona Reference plus Isolator have proven to be the gold standard. Use the shortest possible cables. I have a Ginkgo isolation platform under it: very worthwhile.

Pay special attention to your ethernet connection: consider Etherregen plus additional filters unless you can go fiber directly into the Etherregen.

Enjoy!

I have an Elrod Silver PC on a MKII and have tried a few others - they all provided an upgrade from stock, IMO. I agree 100% with antigrunge2 - isolation seemed to yield great benefit as well. I tried Isoacoustic and Stillpoints and actually ended up using Cardas Myrtle Wood blocks as I preferred them the best. 

The Phoenix was the largest upgrade I have made and highly recommend it.

Happy listening!

Thanks for the input!  I completely agree that isolation is pivotal. 

Cable Comaony recommended Shunyata Venom V14 Power Cord via their lending program.
A bit concerned even though it's a loaner. 
1) Shielded

2) It has a filter - actual noise reduction built in. I've tried digital PC for my front end in the past. I was not impressed. The PC had a filter as well . Rolled off the high frequencies. 

I'm considering ordering another power cord from them. This time. A non digital variant. 

As far as usb. Curious cable has served me well. Shortest length possible. I'm using class A, and a tube linestage so it provides a nice balance. Thinking I might order a non digital power cord from cable company. Obviously there will be a difference. Perhaps good. Perhaos not so good. 
All of this is of this is trial and errror

Refarding Ethernet I find it hard to fathom there is a difference with SQ. It's something I'd have to try. Though definitely skeptical. 
I do not stream much so I'm not too concerned with that factor. 

Regarding break in time. I'll guess running nonstop for a week?  How long on average did things take to settle for your units?
