I’ve been very happy with an AQ Diamond USB cable that I picked up on Audiogon to use with my microrendu > DSD combo - the combo came very close in sq w/ the Bridge II for anything other than DSD - v2.5 of the Sonicorbiter sw and the addition of the Singxer-SU1 gave the microrendu/Singxer combo the edge for me. Upgrading to the ultrarendu continued the trend - hard to tell any difference between the bridge II and the ultrarendu > Singxer-SU1 until I get into well mastered DSD material.
Following John Swenson’s posts on CA in the DIY cable forum I was intrigued by his post on shielding, but I don’t have the time/space to solder these days. So I copped out and ordered a cable from ghent audio - Star Quad (a favorite from my taper days) w/ external shield loop wire. I’m still working my way through my listen list w/ this new cable - what I hear so far beats the AQ cable and as I listen more I am realizing that what I’m hearing is not “brighter” but that the noise floor is lower - and I’m really hearing more detail.
I’m looking forward to the next firmware release for the Bridge II - should bring Roon up to the same release that Sonicorbiter is currently using. I’ve been listening using Roon and UPNP/DLNA (Linn Kazoo) this weekend btw.
