Yeah, I own the Optical Rendu and the Deluxe Optical Module and agree they are excellent. I have added a little augmentation with the power supplies (I'm using ones from Linear Tube Audio) but I understand that there are excellent options available from Sonore as well.
I began hunting for a streamer for a new system a couple of years ago and compared everything to my Innuos Zenith Mkiii that was running in the old system. Once I dialed in on my DAC choice (a Mersson DAC1) I compared everything to the Innuos as a streamer. I tried lower-end stuff from Bluesound (meh) and then iFi's Zen Stream (Better) and then moved up the chain to include Bricasti, an older Auralic, and a couple of all-in-ones (streamer/DACS). Nothing really knocked off the Innuos used as an endpoint. Until I got to the Optical Rendu.
I read a few times about the positive effect of the galvanic isolation provided by the conversion of the incoming ethernet signal to an optical signal. A couple of reviewers that I trust mentioned that this was one of the few things in streaming that actually makes a difference. After trying the Optical Rendu package, I completely agree. Finally, there was something that sounded better than my Innuos. Better separation of instruments and delineation of space and sound stage and dead quiet backgrounds. And all for a reasonable price point. At some point, I'd like to upgrade to the "Ultimate Rendu" but Sonore at all levels makes great products that punch way above their price points and (at the upper end) actually push the state-of-the-art. Don't let these simple little black boxes fool you, if you want a fabulous streamer, Sonore should be on your shortlist.
