Innuos Zen Mini Mk II with an Ayre Codex

Try to insert an Intona Isolator via USB. Alternatively an Uptone IsoRegen will likely solve the issue. The problem most likely relates to timing synchronisation of the USB data stream

Interesting suggestion, so I looked them up. Don't think it would help. My understanding is that the asychronous USB input on the Ayre depends on the clock in the Ayre dac to control the timing by calling for the data from the server to keep a buffer full. This means there is a 2-way transfer of data, which seems to be the disturbing difference. The Zen also seems to have a 2GB RAM cache, storing the data before transfer, which may be complicating the situation. Its beyond me. I can't believe I'm the only one trying to use an Innuos server with a Codex.

I received the dual Pangea cable yesterday. It did nothing to resolve the problem between the Innuos Zen Mk2 and the Ayre Codex. However, I did perceive an improvement in the "reality of the vocal image" listening to Allison Krauss when used from the Zen mini mk2 using the USB 3.0 jacks into the Codex.I am still waiting on Innuos to procure a Codex to figure out the problem.

I'm still not able to resolve that the Innuos Zen mk ii will not link with the Ayre Codex. Innuos has turned my question over to R&D. I found a reference on the web that there is a bug in the Linux kernel that causes a problem with all brands (naming Aurilic, Ayre, Aesthetix, Berkeley, Jeff Rowland) using the Wavelength protocol for USB connections and another reference with problems for the Allo USBridge. I forwarded the info to Innuos, Ayre and Wavelength last week. Waiting on a response.

Let me repeat my suggestion: as a cheap trial, get a USB hub from amazon inserted in your USB coneection. If that solves the problem, the Intona solution, while more expensive will be superior. I had the same issue between an Innuos Zenth Mk3 and an Antelope Zodiac Platinum
