Not sure if this has been posted yet, but a BNC Coax optical bridge was just announced that specifically states it supports Chord's DX! This could be next level with regard to taming RF interference between the M Scaler / Blu MkII and Chord DAC!
"Audiophiles have sought to minimize noise transmission using cleaner sources, ferrite laden coax cables or myriad other tweaks. These solutions are partial or, at best, only attenuate the problem to subjectively match the noise floor. For those with the most resolving systems and highest appreciation of musical transparency, the optical galvanic isolation of OPTO•DX is objectively superior."

Headfi review with M Scaler and Blu: https://www.head-fi.org/showcase/audiowise-opto•dx-optical-isolation-bridge-for-dual-spdif.23757/
I received my OptoDX boxes Saturday morning and had them playing in my system all weekend. These things are the real deal. They did exactly what they claimed to do, clean up noise. I have not heard my system with this low of a noise floor before. The biggest change I noticed is just how sweet and "real" the treble sounds now. I actually look forward to the next song on shuffle, instead of wincing in fear of hearing the hardness it had before in the upper region. Bass resolution and soundstage depth also increased, as well as detail resolution, but oh my the treble!
I am running an Innuos Zen Mini with LPS using optical out to the HMS which is running off a pilot pro 2 battery with High Fidelity Cables CT-2 cables from HMS to Dave. Dave is being powered by a HFC Pro series power cord. Dave is feeding the HFC Trinity Helix Headphone module which is feeding the Empyrean and HE1KSE. What is surprising is that even before the OptoDX boxes, I thought I was running a pretty noise free system, but the boxes are a real eye opener to the high frequency noise the HMS is producing. Maybe from the FPGA processing?
I tried using the BNC patch cables that come with the boxes, but I found my HFC CT-2 to sound better when used from the RX box to Dave.
Both boxes were being powered by separate pilot pro batteries and Ghent Gotham DC cables.
Great job Dan!!
