@hilde45 hey you have quite the setup and room. In one of your photos I see you have a Bluesound Node. Have you actually tried other streamers because the NODE is more of a lifestyle product. While the Node is a good entry level streamer and DAC it's limited. I tried a couple different NODES and compared them to Lumin and Innuos on McIntosh, Yamaha, Prima Luna, and Accuphase components and NODES don't sound nearly as good as other notable streamers, not even close. So I'm curious as to which other streamers you tried with your system.
Do streamers make a difference?
Just added the Nagra Streamer and I can wholeheartedly say yes, it does. Without buttons, remote control or a screen, it is elegant in its simplicity. On the other hand, its music selection is anything but simple as it accommodates Qobuz Connect, Tidal Connect, and Spotify Connect. It is Roon ready/Roon Tested, JPLAY Certified, and plays with Audirvāna, Airplay 2, UPnP/dlna for local files and vTuner for radio access.
It is a wonderful device and I hear more music and I hear the music more clearly. But in the interest of full disclosure, is it the streamer or the result of removing a USB connection?
My previous system used a Roon Nucleus Plus as server and streamer and was fed via an AudioQuest Vodka RJ/E ethernet cable from an Xfinity XB7-T modem/router. The Nucleus was then connected via an AudioQuest Dragon USB cable to a Playback Designs USB-X4 interface, which connected to a Playback Designs MPD-8 DAC using their proprietary high-bandwidth fiberoptic cable. In addition to the fiberoptic connection providing galvanic isolation, the USB-X4 also reduces jitter with a clock that is identical to the clock in the MPD-8.
The new system has the Nucleus and the Nagra Streamer each connected via Vodka ethernet cables to the Xfinity XB7-T. Nagra and Playback Designs share design technology and the Nagra Streamer connects to the MPD-8 with the same proprietary fiberoptic connection as the USB-X4 and also incorporates the identical clock, yielding the same sonic benefits in terms of noise and jitter reduction.
There is definite improvement in terms of detail and space. There is simply more to the music. I venture that the streamer contributes the lion’s share but acknowledge that I have removed a USB connection from the flow, which may also contribute to the difference.
While I believe it is a great addition to my system, the Nagra is not for everybody since its connectivity is limited to only two outputs, the second being an S/PDIF. The USB port is an input for hard and flash drives.
The matching Nagra Compact PSU almost doubles the purchase price so I have ordered a Teddy Pardo LPS to replace the included SMPS.
I do not use a network switch since I have only the two ethernet connections and see no reason to isolate one from the other. I also believe clocking is not an issue, but I am interested in what others think on both fronts.
Of note, EMM employ a similar proprietary fiberoptic cable set-up but utilize a different format that is not compatible with Nagra and Playback Designs.

I do not know if streamers make an audible difference or not, but ensuring the best connection for whatever transfer format one uses (USB, S/PDIF, I2S, etc.) seems to be universally supported, with the connection to the DAC being regarded as the most critical. While I am able to say I hear an audible improvement going from a Roon streamer to a Nagra, it may just be because I removed a cable from the equation. |
@yyzsantabarbara I A/B compared the Lumin U2 and Sonore OpticalRendu Deluxe with the same Finisar 1318 SFP. The Lumin had an inky black background and a smooth presentation. However, I preferred the more lively presentation of the OpticalRendu. I asked the Lumin dealer if there is a sound quality difference between the U2 and the U2X and he said that he could not hear a difference. |
@rrboogie Thanks, that is very informative for me. I at one time compared the Lumin X1 | Sonore OpticalRendu Roon Only | Playback Designs STREAM-IF. I owned all 3 at the same time. They all sounded different. To me the Lumin X1 was very lively, like a wild child was how I described it back then. The Sonore sounded more buttoned down, less lively. The PDB was in the middle. All 3 were excellent. I ended up keeping the OpticalRendu and selling the other 2. I have the upgraded power supply from Sonore and also the cable. Though I do not think that makes any difference. I had 3 opticalRendu's at one time with various power supplies and cables and they all sounded the same to me. I am down to 1 OpticalRendu and 2 DACs so a bit of a pain to keep flipping USB cables. I am likely going to get the new OpticalRendu which is supposed to sound better than the old one I have. |
My system has similar machinations to remove USB and use of fiber between an Innuos Statement and Lampizator GG3 and the results are in line with what you and @mclinnguy describe. The Statement's ethernet out feeds a OpticalModule. The OM's fiber feeds a Signature Rendu. The SR outputs USB to an Antipodes S20 DDC and then S/PDIF BNC to the Lampizator. If I use the SR's USB to the Lampizator everything goes south. I think its not either or but both that make the magic. I just tried a passive DAC cable in place of fiber and the noise level clearly rose. |
