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

[Getafix]

I bought those but thw fiber cable doesnt fit. There is metall in the second connector side.
What am i doing wrong?

I’m afraid you bought the “Single-Mode Single”, you should have chosen “Single-Mode Dual”. Regarding the sfp modules.

Split the cable into two. Use only one piece.

Most of us agree that as a stand-alone device, the R26 performs the best when it is fed by its LAN port.
However, as I reported a few months ago, in my system, I get the best results with its I2S port when it is fed by an AGD DI-20HE that is associated to my external GentooPlayer/Diretta streaming setup (as it appears in my signature).
With the I2S port of the DI-20HE, the streamed sound is limited to PCM 384 kHz. Yet, the result more refined than with the DSD512 that I can stream to the LAN port of the R26.

Last week, I sent the DI-20 to my retailer for maintenance, and I’ve been listening with the internal streamer of the R26.
Today, I decided to try the I2S port of the R26 with a PI2AES that I keep in the closet. (In this GentooPlayer/Diretta streaming setup, the PI2AES simply replaces the Allo USBridge Sig, the iFi iGalvanic 3, and the AGD DI-20HE that appear in my signature.)

And I managed to beat the LAN port of the R26 again. Though the PI2AES is limited to PCM 192 kHz, its sound is more refined with small details that are lost with the LAN input of the R26, though I stream DSD512 to it.
To optimize the PI2AES in my system, I power its HAT, and the RBi3 with separate LPSs. The HAT is powered by a KECES P8, and the RBi3 is powered by an Allo Shanti.

I have had a similar experience to you. I tried the R26 via Lan and it does indeed sound great but when I used my Hifi Rose 150b to the Gustard U18 via USB and then the U18 to R26 via i2s there was a audible improvement to my ears. Wider soundstage, crisper details and more intense transparency .

On a side-note I did do the FMC hack / upgrade and once again had an audible improvement. So to summarize in my system with the FMC upgrade along with the i2s use of the U18/R26 I am very satisfied.

I think the quality of the DDC (digital to digital convertor) as well as the external streaming source make a big difference with the R26.

But if you want an easy solution that sounds great just use the LAN port and stream via Roon and you will have a stellar setup. I still suggest the FMC upgrade.

I still suggest the FMC upgrade.

For what its worth my experience with FMCs and multi-switch setup. To get ethernet streaming sounding at its best, its painful but worth testing out if you have the opportunity to do so. I was skeptical at first, especially when my line of work is in IT and my fellow workmate, who is also in IT but is more qualified as a network support engineer, loaned me the test equipment that changed my perception before I went out and sourced it myself documented below.

^I don't have your complete setup but I also use TP-Link Mesh unit with my setup and it fixed the pops I was getting in the music using HQPlayer over USB. Loving ethernet through mesh unit. I really feel like I have it all, but perhaps it can get better...but very happy with my setup atm.

Before I got the TPlink Mesh units, the only way i could get a solid network connection was through EoP - those things are noisy as f@#$. I was lucky enough to get hold of 6 M9Deco's off the bay ridiculously cheap as the seller went Wifi 6e. That was the start.. until my workmate brought over those iPowerX 12 units.. We tried an LHY 12 LPS too, but we couldnt hear much of a difference, so I couldnt see the justification for it over an iPowerX. Its not for everyone, but see if you can get a loaner from a friend and test it.

Will that work just aswell as getting diffrent trancievers?

 

[m-i-c-k-e-y]

Your picture tells otherwise.. Or I don't get the question. Meaning will it work with other set of transceivers? Assuming it has the same spec, yes, just plug in both cables..

Take a look at VH Audio,
They have the same offer.
Could be interesting for Us people.
