GUSTARD DAC-R26 Balanced Decoder R2R+1Bit Dual Native Decoding Music Bridge

Hi Cam!

1. If the sw10 replaces my switch on the “dirty” side of my network, why would I connect its master clock to my R26 on the “clean” side? Bridging a BNC over my fiber convertors would negate my FMCs, and especially with how prone clocks are, add noise and jitter to my R26.

The OCXO clock on the SW-10 resides on a separate m/b and linear power. Enough for you?

2. If the switch is connected to the “clean” side of my network, by becoming the last FMC, why would I connect all of my noisy “dirty” network components to its Ethernet ports? I would also then be connecting the R26 to that same switch, again negating the FMCs and most likely adding noise to the DAC.
Think this is a no-no. The idea is to separate the dirty things right?

If the answer is a second switch, why the heck does the sw10 have 17384917 Ethernet ports?!

Think its the best config if you have money to spent: Two SW-10 connected by FO. All dirty connections to SW-10(A), connected by a FO cable to SW-10(B). Clean RJ-45 to R26 or Streamer/DAC. Clock from SW-10(B) to R26 or Streamer/DAC.

Why have 17384917 ports? Thinks its a design choice:
- based on Cisco Business Series Smart Gigabit Ethernet Switch -> reliable brand.
Of course there are many 4 ports + SFP swithces. But with lesser names. Don't know about other considerations like supply or OCXO integration issues. CISCO-Meraki switches have sometime now are popular as bases for such OCXO mods.
- as an AIO idea.

Honestly not really with how sensitive clocks are. It’s sitting right on top of the dirtiest part.

Exactly

I see what you’re saying but that’s nuts for a manufacture to do. I could never support LHY if that was their original intent. For 1 that would be a very poor design choice, and an insult to the consumer.

New universal USB driver (v5.70) is out but link doesn't function yet.

A26 has new firmware (1.41) its chagelog is:
1.Fixed known bugs.
2. Optimize memory consumption.
3. Upgrade upmpdcli to [1.7.7].
4. Upgrade HQplayer NAA to [4.4.0-56].

Maybe R26 will have a similar upgrades.

I new to fiber. Due to my only need for one port to my setup ......I am thinking going from router -cat 6 - optical module - fiber cable - sw10 - cat 6/7 to streamer/r26.

Due to little use of the 10 (!) Port on the SW 10 I will wait for news on ethergen 2.

Btw - does anyone have an opinion.on the ifi power smps...I have that on my streamer and wondering if a LPs would give me any additional benefit.

Have you seen anyone testing that Ifi-audio LAN iSilencer? I wonder how good that is, compared to the FMC solution? 😊
I haven’t. But I don’t think it will do the job that fiber does. Fiber is immune to RF and EMI and will not pass high-impedance leakage currents from any connected devices.
Oh and add lightening protection for any devices connected on the other side of it.

As far back as I can remember I have not had a lick of success with technology. I have one of the very first R26 and am still running the original set up. I have not run a single update as I know from my history the only out come would turn my dac into a brick. Right now as I sit everything works great, I love the sound and don’t see a need to mess with it. Can anyone tell me if there is a down side to me leaving well enough alone or am I heading for trouble down the road?

If it ain't broke.... fair enough. That was my thinking too for a while, but the proffered fix of loud popping on DSD tracks was enough of a motivator to upgrade the Gustarender firmware to v1.4 from the v1.3 my Sep model came with. Larger display text sounds good so really ought to upgrade the main firmware too.

In terms of downsides in taking your time to upgrade (if ever)... if you don't have any issues that the fixes or improvements address, then don't think there's any. No rush.

I have the Lan iSilencer and still use an FMC solution in between. I feel the Lan iSilencer is more complimentary to the overall network, rather than it being a replacement in lieu of say a switch within the network. As @camrector pointed out, there is real benefits to having fiber between switches.

Im in the same boat. The SW10' use case is not one for my requirement. I already have an EtherRegen, so will wait for ER2 to emerge and bite.
As for the ifi IPower smps, i have all 3 versions - ORG, v2 and X and the iPowerX is IMO the best of the lot. I have tested the iPowerX against the LHY 12v LPS and I preferred the iPowerX. The LHY gave a cleaner, but leaner presentation, with some emphasis on the highs but the IPowerX had more meat on them bones, and better midrange.

$200 total is all you need for the fiber.
In did the FMC solution for around €31, two modules and fibre cable using Aliexpress, if anyone is interested I'll post links. That €31 even included two on plug switch mode power supplies so at lease one should be changed to a decent linear power supply on the clean side which will cost extra. Result using the FMC with LPS was an obvious improvement to the overall sound, much better background detail and believability with better imaging.

Another way that works well for me (and others). It depends, of course, on your system configuration (server position, player, etc).
The purpose (for me) is to limit the intermediaries, even of quality. If you add a swith, you also have to deal with its power supply...
So, I have 2 mesh boxes: one at the output of my internet box, the other before my server (Roon/HQPlayer). A JCAT ethernet card on the server: eth1 > ROON > HQPlayer > eth2 to the A26 and its internal streamer. No switch: modern cards handle crossover (CAT5 UDP MicroRun Monoprice with iFi Silencer).
