What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 96/100
Reviewers describe an exceptionally transparent, natural and musically absorbing streaming source. Its standout contribution is unusually complete preservation of musical timing and transient information, while the other review praises lifelike tone, vivid imaging and convincing recorded ambience.
Overall Sound
96/100
Positive Feedback found voices, piano, acoustic bass and orchestral space rendered with remarkable realism, calling it the most analog-like presentation of digital files the reviewer had heard. Audiophile Style likewise judged it capable of improving nearly any system and preferred its USB-fed playback to Ethernet and AES inputs on reference components.
Digital Signal Integrity
96/100
Audiophile Style singled out its preservation of attack, decay, sustain and release as better than anything the reviewer had heard, with no added sonic flavor. The optical network path is also reported to bring substantially greater noise rejection, stable hardwired operation and no playback glitches.
FEATURES USABILITY PERFORMANCE 89/100
The Rendu platform combines optical-network capability with flexible integration into an existing DAC-based system. Roon discovery is reported to be quick and straightforward, while the optical architecture and choice between integrated and external-power-supply versions offer meaningful system flexibility.
Streaming Software
88/100
The Signature Rendu SE was found by Roon in roughly sixty seconds, and the reviewer reported stable, glitch-free use once connected. A 60-day Roon trial is included, although the reviews provide limited detail on control-app design, metadata handling or support for other streaming ecosystems.
Features Connectivity
90/100
Optical fiber networking via the System Optique board and SFP transceiver is the central attraction, designed to isolate the streamer from network-borne noise before conventional Ethernet connection onward. Audiophile Style also praises the Rendu range's combination of flexibility and advanced functionality, including the option of an integrated Signature or externally powered opticalRendu approach.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
89/100
The Signature Rendu SE incorporates a custom internal power supply, improved grounding, an updated optical board and SFP transceiver, plus Sorbothane-equipped custom footers. Reviewers present these as purposeful refinements to isolation and system execution, though they offer little commentary on enclosure finish or long-term durability.
Value for Money
85/100
The reviewed System Optique configuration was listed at $3,745, while the supplied current price range is $5,350-$5,500. Neither review directly weighs whether the Signature Rendu SE is good value against competing streamers at those prices.

Specifications
Manufacturer's Description — Sonore
***The Signature Rendu SE received the 16th Annual Positive Feedback Writers' Choice Awards for 2019***
Introducing the Signature Rendu SE Deluxe, the absolute finest streaming USB source we have made. The Signature Rendu SE Deluxe is the natural evolution of Sonore’s ultraRendu and Sonore’s acclaimed Signature Power Supply.
The Signature Rendu SE Deluxe takes fiber optic Ethernet input or cable ethernet input and renders it to a perfect, ultra-low noise USB feed to one’s USB DAC. While the opticalRendu is a revolutionary product, the Signature Rendu SE takes off from the opticalRendu concept, improving on it by refinement and attention to every detail. The SE takes advantage of single chassis design, allowing close coupling of the power supply and processing board for the ultimate in ultra-low impedance and ultra-low noise power delivery. The SE processing board uses a large footprint to allow for multiple independent low noise voltage regulation stages, and better physical separation of the Ethernet processing and USB output sections, further reducing noise and crosstalk. Two ultra-low phase noise (so-called “femto”) oscillator are used to govern all processing, network circuits and USB audio circuits.
The Signature Rendu SE Deluxe is systemOptique Certified.
