The Sonore Signature Rendu seems to be "da bomb"

Mike said:
What I would love to hear is the BDP2/BDP3 or Rendu/BDP3 via i2s. But Bryston not having it's own app is a real negative (sorry James, but you guys REALLY need a Bryston app), these Bryston players have been out forever now.

I have a simple way to add i2s output on the Bryston. However, from experience I can tell you it's not worth it unless you can guarantee isolation and clean power to the board.

Update: I tried JRiver/Jremote. Worked fine, but there was a significant difference in volume (lower). I checked the settings on JRiver on my Mac and it was full.

I think I'll stick with the Audionet app or the Auralic Aries app (Lightning DS).

We should check the setup to assure JRiver is not down sampling to PCM.

The more I read about digital, the more I delay wanting to rush in as it feels like it's a constantly moving target with different implementations and set ups (never mind the different file formats: PCM vs DSD, and now MQA for streaming, etc...). I am waiting for the day when you get a single ripper/server/DAC where you house everything in one box and if you want to rip a CD from a physical library and store it it digitally it does it for you in bit-perfect fashion and does the storing and cataloging automatically or if you want to download/stream from an online music store you can do that too. The way things are right now, you need a freaking computer science degree to set up either a server with on-board storage or separate NAS storage linked up either to the DAC directly or via a streamer with multiple communication link formats. Too complicated and it's constantly changing! If you need a post-graduate degree to listen to your music, it's going to remain a very small niche market until it can get simplified down to a simplified one-box deal with a set-it and forget-it type functionality.

I'm one of the developers of Vortexbox and it's pretty much exactly what you describe above. You don't have to build them since Andrew sells ready made Vortexbox units. Also, Andrew works with me to provide a Synology NAS with the server software preinstalled. My point is that there are simple options available...

How do you instal this on Synology ? Do you need to do it manually ?

I have installed the Minim Server previously from the Synology 'Apps Store', but can't find the Bubble in there.

That APP is installed manually and you have to download the APP from the developer's website. Also, this APP is not needed unless you want OpenHome compatibility. The Synology's server and or MinimServer are very good options and can be installed from the Synology's package manager.

Mike, When you compared the Lumin and SSR did you ever run digital out of the Lumin to the Direct Stream to make an apples-to-apples comparison of the two streamers?
 
Yes. And compared it to the Auralic Aries too. There is no doubt the i2s into the DS is superior than coax, usb or BNC.

BUT - I still have to use a computer with the SSR and that's not my thing.

Like I've said before, all this digital is a little like picking the tallest midget.

Paul, if you want TRUE TRUE TRUE DSD, check out the T+A PDP 3000. According to the manual, most speakers and amps can't handle "TRUE" DSD. Download here: http://www.ta-hifi.de/fileadmin/user_manuals/hv-serie/UM_PDP3000HV_100_DE_UK.pdf



The warnings are everywhere. So given this, what the hell is "native" DSD if it's not "TRUE" DSD?

I'm going to spin a record. This digital stuff gives me a headache.

Sorry to be thick here Mike but to be clear are you saying i2s on SSR was superior to the coax, usb and BNC on the Aries and Lumin?

Yes, but digital output matters little if the digital input isn't up to snuff. The DS is very i2s and usb focused. I will say, that after the latest update to the DS, the USB got a LOT closer. The others didn't change.

Oh crud that confuses everything; so it might be that the DS just likes i2s. Did you happen to compare spidf across all three dacs?

According to Ted and Jesus, it likely means that the new FW cleans up the jitter on USB end and i2s is far less affected as it was much cleaner from the start. Makes sense because of the superior PDN that cleaned up ethernet crud (without creating any other distortions which would exists even in the signal line) in the conversion engine to i2s which is galvanically and RFI/EMI isolated and that purity goes straight into the dac without any other corruption.

That is the working theory anyway.
 
Mike, I could not find the reference to True DSD in the link you posted.

OK, read it. Its just preset filter levels for DSD. Its is known that HF noise in DSD64 if untreated 9at high energy levels) can fry tweeters and so they have a low filter option DSD4 that is suitabule for robust speakers like Electrostatics. TrueDSD engine sounds like marketing speak, in that they use a 1-bit converter, so some processing is still going on. Likely sounds good, but not striking me as an absolute purist approach. DSD can be played back with filtration only and that is what I am used to and what Adam/Bruce and others have been saying for a while.

Interesting. T+A claims there True DSD is the purest approach (no filters). Do you not agree?

I also read that they said True DSD is fine for electrostatic speakers, but needs to be used with caution with traditional "dome tweeters". Did I read that wrong?

[TABLE="width: 428"]
[TR]
[TD]"DSD signals are characterised by a high-frequency noise floor in the ultra-sound region. This noise is inherent in the DSD principle, and is present in the recording itself. In basic terms the higher the sampling rate, the lower the high-frequency noise. At DSD64 this noise is by no means negligible, and may constitute a problem for amplifiers and loudspeakers connected to the system. Although rigorous filtering of the noise is technically possible, these solutions have undesirable effects on sound quality. In our opinion the filtering option should always be kept to the minimum necessary level, and that is why the
PDP 3000 HV offers the facility to fine-tune noise suppression, noise-shaping and signal processing accurately, in order to match the requirements of the recording, amplifier and loudspeakers."

One must filter DSD for playback, otherwise the noise is overwhelming and artifacts are easily heard. There is an art to filtration. They have different levels of filtering, clearly, with the different options, but they also clearly state that its run the their 1 bit conversion engine. What they seem to do is run a "turbo" option with minimalist filtration which they warn you to match with high bandwidth amps/Electostatic speaker combo, as these apparently block the tweeter killing HF noise/energy. They also suggest that you playback DSD128 and higher in the low filtration modes (easy to do with their upsampler).

Not a bad offering at all, especially with disc playback ability....any idea of price...seems "not cheap".
 
So? Spec wise, a good product? The first spinner/DAC I've seen with a separate section for PCM and one for DSD. Two outputs and even two power cords.

Mine is on order! [emoji41]
