The Zenith SE is in the house. I was also able to borrow a friend's dCS Network Bridge. The Network Bridge is incorporated into the Vivaldi Upsampler and so I have heard its impact before but this is the first time I have had a chance to directly compare it to my latest server build.
I've had the chance to listen to each of these units for the past 3 days. Last night, I had a few friends over and each offered an opinion. There was no unanimous consensus between these two.
My overall system has gone through changes (and will continue to evolve up until Rob Watts' digital amps become available). This is my present system.
Server/Streamer > Chord Blu Mk2 > Habst Digital BNC cables > Chord DAVE > HFC Pro Series RCA interconnects > Pass Labs XA60.8 monoblock amplifiers > HFC Pro Series speaker cables > Martin Logan Renaissance ESL 15A electrostatic speakers. Power delivery is via two 20amp dedicated lines, dual Denali 2000T line conditioners, HFC MC-6 Hemisphere distribution block and a full loom of HFC power chords. Each server/streamer was powered by an HFC CT-1 Ultimate power chord. The Zenith SE was connected to Blu Mk2 via USB and the dCS Network Bridge was connected to Blu Mk2 via SPDIF. With Blu Mk2, USB is equivalent to SPDIF with regards to SQ.
I'll get a few things out of the way. Both of these units are excellent and the consensus was unanimous that in my system as stated, either of these units is a large gap better than a Windows 10 laptop on batteries running Roon. It was also a unanimous consensus that my current server build is better than either of these units but in different ways. For those not aware of the details of my current server build, here it is:

To be fair, what I have now was built and fine tuned for my specific system and to my preferences and so not surprisingly, using gambling nomenclature, it has a "house advantage." For those not wishing to build their own servers, either of these would be considered state of the art and I would have no reservations recommending either of them depending on your priorities.
dCS Network Bridge ($4,250):
This is a fairly small footprint FPGA device that does not have the full functionality of the Zenith SE but in some ways, it is better than the Zenith SE. It is a minimalist design and comes in either silver or anodized black. Construction quality is typical of dCS's high standards and their build standards are second to none. It features an Ethernet network input and it is via this input that this Network Bridge was designed to function at its best. While it also features a bidirectional USB port, at the present time, this is useful only as an input for music playback. With a soon-to-be-released firmware upgrade, this USB port will eventually have the capability to connect to a USB DAC. At the present time, connection to a DAC is only via dual AES/EBU (PCM up to 24/384 or DSD128) or SPDIF (PCM up to 24/192 or DSD64).
Unlike the Zenith SE (or Antipodes DX), the dCS Network bridge is only a renderer rather than a full server. It requires a NAS or local computer connected via Ethernet network and it shares much in common with a Focusrite RedNet. Also unlike the Zenith SE (or Antipodes DX), this device is incapable of ripping CDs. It is a one trick pony but what it does, it does very well.
While dCS has an IOS app that can be used to control the Network Bridge and also play back music directly from Tidal, Spotify or from your NAS via a proprietary interface, it is via Roon where I found it to be most easily utilized. For you to be able to use Roon with the Network Bridge, you will either have to have Roon Core (or Server) installed onto your NAS or onto another PC in your network as the Network Bridge serves only as a RoonReady endpoint.
With regards to SQ, what the Network Bridge incorporates that the Zenith SE fails to even consider (or at least mention in their marketing) is high quality clocking and indeed, this device leverages dCS's expertise in this regard. While the Chord DAVE is presumably immune to source jitter up to 2uS, this clocking makes a very noticeably difference, nonetheless, with regards to detail resolution and layering. Does this amount to a noise issue or a timing issue? I'm not sure but against the Zenith SE, files are resolved better and the difference is easy to hear. There is definitely a succinctness to how sounds start and stop and this detail resolution is comparable to what I am hearing with my server when combined with Mutec's REF10 master clock. Where the Network Bridge falls short is with tonal weight. Compared against both my server and against the Zenith SE, it sounds a bit thin. This could be a power supply issue because in addition to a denser tonal weight, both my server and the Zenith SE have better dynamics. What the Network Bridge has up its sleeve that the Zenith SE doesn't is the ability to connect to dCS' external master clock. Supposedly, this improves SQ significantly. While I don't have a dCS Master Clock to connect to, I have ordered a Mutec MC-3+USB that I will utilize as a word clock generator and combined with my REF10 Master Clock, I will see how much better things get.
Innous Zenith SE (approx $7k):
This is a standard sized component similar to an Aurender N10. As I don't currently have an N10 available for direct comparison, I can't tell you for sure if it is better than an N10, but based on memory, I would say that this is a much more dynamic sounding server. The difference between the Zenith Mk2 and the SE is supposed to be a better PSU and I would have to agree, the PSU used on this unit is very good. Compared against my Paul Hynes SR7, for the first time, I am hearing dynamic contrasts of equal measure and so this is saying a lot. Like the dCS, this unit is very solidly constructed with exquisite attention to fine detail including the incorporation of very good footers. With the dCS Network, I was able to improve it by placing it on Stillpoints. With the Zenith SE, these footers are the equal of the Stillpoints.
Unlike the dCS Network Bridge, this is a full fledged server that functions as both server and renderer in one box. Like the Antipodes dX, it excels via its USB output but unlike any other server I've seen before, it appears to feature a dedicated Ethernet output designed to connect directly to an Ethernet streamer. I have yet to test this feature but I am very intrigued. If it has a similar impact to the LAN bridging trick that I first detailed on CA earlier this year (
https://www.computeraudiophile.com/...-audio-streaming/?tab=comments#comment-613370), then I could see the owner of a Zenith SE purchasing a network streamer such as an sMS-200ultra, ultraRendu or even a dCS Network Bridge for use in a 2nd system.
Like the Antipodes DX, the Zenith SE utilizes a customized Linux OS that is extremely easy to setup and use, even easier than the OS used by Antipodes. It can rip CDs to either WAV or FLAC although I have not yet tested this feature. It also includes Roon Core built in but can be used as a Roon Ready end point device. This is an extremely versatile device.
As far as SQ, the first thing that is readily apparent is dynamics, both macro and micro and I have not heard better. It is tonally rich and very satisfyingly musical, however, compared to my server, there is a subtle but noticeable HF harshness and dryness that is not present in either the dCS Network Bridge or my custom server. Is this a noisy clock issue or a noisy SSD issue? I'm not sure. It's biggest drawback, however, is that it lacks that last bit of detail resolution that the Network Bridge and my custom server provides although you don't know its missing until you do the comparison.
As happens frequently, with my group of friends that came by for a listen yesterday evening, as I have already stated, there was no unanimous consensus and 4 of my friends preferred the Network Bridge while 2 preferred the Zenith SE. If I had to choose one for myself, I would probably choose the Network Bridge although I would not be unhappy at all with the Zenith SE. If I already owned one or the other, I'm not sure there would be a compelling enough reason to switch. If someone is in the market for a small, single-box, reasonably affordable ($4.2k) device that you can set and forget and if streaming from Tidal or Spotify is what you do most, it would be hard to do better than the Network Bridge. If someone is in the market for a single box, no fuss, "all-in-one solution" including the ability to rip CDs and internally host a large music collection, it would be hard to go wrong with the Zenith SE. How it compares against the new Antipodes DX Gen3 is anyone's guess and hopefully, I'll have the chance to make that comparison in the coming weeks. If all goes as planned, Johnny Moondog will be joining me and he will bring along his Audio Alchemy DMP-1 for comparison.
Regarding the 432 Evo Master that
@bmichels mentioned, this server was introduced in Munich this year but unless I can directly compare it against something I know, it's hard to know how good it is and coming from Belguim, I'm not sure how I could easily get a hold of one for comparison. Maybe it's a gimmick but what attracted me to this company's products in the past was this 432Hz processing mode that is supposed to sound more like real music. I suppose it may have a similar effect as Phasure's Lush USB cable.
