New AES3/USB interface?

Hey all, I’m looking for a new way to interface my PMC TwoTwo 5 system with my MacStudio. I’ve currently got a Mutec MC-3 +USB unit connecting via AES3 (digital) but I’m having an issue where my PMC units will reset every so often during audio playback. I’ve had both PMC monitors and the sub replaced and I’ve since upgraded from an iMac Pro to the MacStudio — and still seeing this odd behavior. The only thing I can think to try is a different way to interface the PMC system with my computer.

My PMC studio monitors are active with on board DACs

Does anyone know of anything else out there that delivers the same (or better) options as the Mutec? At a minimum, it needs to have AES3, USB and DSD support.

Any help is appreciated

@designsfx Ah, I assumed you meant sample rate change from track to track.

There is no other hardware other than the MacStudio, Mutec MC-3 and the PMC monitors.

I did just hear back from Mutec. They suggested maybe the USB cable wasn't allowing for enough power but I'm using external power so that's a moot point.

I wonder if a higher quality USB cable is necessary?

@hedkase-

I would be very surprised if it were cable quality- I’ve pushed $2 USB cables into video processors that were doing more work than that without issue. It’s a weird problem. 
Is the Mac the Master and does the Mac see the Mutec as the device on the other end of the USB interface OR does the Mac see the PMC on the other end of the USB (device/midi control in Mac OS)

My Mac does see the MC-3. Roon shows the MC-3 as the endpoint in the system.

It is a very odd issue and its driving me nuts ;)

I guess I can try that Matrix Audio X-SPDIF 2 and see if the change in hardware changes anything.

@hedkase 

is the MC3 set to act as a clock generator or distributor?

I've tried all the settings. The only mode I get audio from is INTERN/RE-CLK. I unfortunately don't know much about this unit. It was a means to use these monitors with my desktop in my office.
