jabbr Posted May 23, 2017 Share Posted May 23, 2017 15 hours ago, m5sime said: Yes. With a couple of RAM chips and an Xilinx 7010 SOC (2 ARM9 cores). It is quite close in design to the Zedboard that Xilinx have for system builders. https://www.xilinx.com/products/boards-and-kits/1-58nuel.html Sale price of this is circa 170 USD I assume that everything that is needed is in this SoM including the SW. The main question is how much this module costs an OEM integrator (with Ravenna licensing etc).. I would love to see this in the hands of the chinese integrators offering a Ravenna/AES67 AOIP to AES/I2S/SPDIF interface adapter and of course also native AOIP DACs.. Is the Merging "ZMan" $170? That would be off the chart, particularly if included SW/IP. The Xilinx Zynq is a terrific series of chips that I've working with. The 7010 if that's what the Zman has, is the lowest performance chip in the series. The architecture combines ARM cores along with an FPGA communicating over an AXI bus. The ARM (PS side) typically might run Linux and communicate with the FPGA (PL side) using device drivers. Having multiple interfaces, each listening on its own port would be no problem, eg Ravenna/AES67, NAA, Roon, SMB etc. Perhaps there is a way to get the I2S/DSD sound out, rather than across a PCI bus but who knows?

Sorry for being off the topic a little bit, but are you suggesting it is difficult for DSD1024 to be bit-perfect to pass-through to D/A section? what's the limit for discrete DSD DAC being able to support DSD1024 at the moment in terms of DAC design? I'm aware if using HQplayer to upsampling DSD1024 with certain filter, the algorithm must be huge and current hardware (CPU) may not fulfill, but must be some other reasons for DACs like T+A or your DCS1 only support sampling rate up to DSD512 at 44.1 and 48 bases.

The current limitation is typically the interface which is often underpowered. Consider DSD1024 is about 45 Mhz, so everything has to have at the very least this bandwidth. More actually because there can be many things that have to happen between a clock cycle. Optical isolators start to have a hard time at 50 Mhz, but GMR can double that. Some CMOS logic has a hard time above 50 Mhz etc etc. Realistically the upper limit would be DSD2048 but the other issue is that there are diminishing returns to increasing the clock rate -- the very close in phase noise actually increases as the clock increases -- it very well could be that the "sweet spot" is DSD512. 3 hours ago, louisxiawei said: I'm aware if using HQplayer to upsampling DSD1024 with certain filter, the algorithm must be huge and current hardware (CPU) may not fulfill, but must be some other reasons for DACs like T+A or your DCS1 only support sampling rate up to DSD512 at 44.1 and 48 bases.

Popular Post The Computer Audiophile Posted May 23, 2017 Author Popular Post Share Posted May 23, 2017 Hi Guys - Thanks for all the posts from people at the show and interested in the show. I think we are on to something here. When many people post, even a little bit, the coverage is far better than what one person (me) can do alone. Plus, we get great opinions about what was interesting, innovative, and sounded good/bad.

Popular Post The Computer Audiophile Posted May 23, 2017 Author Popular Post Share Posted May 23, 2017 By the way, I met Morten Lindberg from 2L at the show. What a cool guy. I wrongly assumed he would be very hoity-toity, given the content of the albums on his label. I was so wrong. He is very down to Earth, knows a ton about good sound, and about the music business. I'm so happy I met him in person. Jud, Solstice380, christopher3393 and 1 other 4 Founder of Audiophile Style | My Audio Systems Link to comment

Thanks a lot for the detailed reply. Seems like I'm out of date. First time to know DCS1 can support DSD1024 as well, although still seeing DCS1 on HQplayer's website still claims that it can support up to 24.576 MHz sampling rates. Maybe the DCS1 you mentioned is a bit different.

monteverdi Posted May 23, 2017 Share Posted May 23, 2017 I thought that many of the listening booth were quite o.k. often better than the hotel rooms I am finding at US shows. But he main floor exhibits with out a separate booth were absolutely unlistenable. This applies to many demos using headphones. Even if at lot of open designs are sounding better it is an idiotic choice under these conditions. The epitomy of this was the Sonoma Headphone demo, a new electrostatic design and the completely clueless rep was just talking to another visitor next to my ear. Thus I have no idea if that is a headphone to investigate, just a waste of time! The Computer Audiophile 1 Link to comment

Soundsmith for example offered a good listening environment in a small booth in Halle 3. Matt "I want to know why the musicians are on stage, not where". (John Farlowe) Link to comment

Maybe the DCS1 you mentioned is a bit different. It depends, how high the flip-flop can go. In my version FF can go to ca 170MHz. Analog stage behind flip-flop is another story, just filter frequencies not optimised for that. Sorry, english is not my native language.

EuroChamp Posted May 23, 2017 Share Posted May 23, 2017 I was at the show on Saturday only, but all day long. I listened to almost all of the systems. Some of them where not very promising, when I entered the room, so I left immediately and went to the next one. I don't want to talk about, what was not so good. But I want to list my best sounding systems in the order, I listened to them: Blumenhofer with Octave (digital) Joseph Audio with Alluxity (digital) Tune Audio with Trafomatic (vinyl) Marten with MSB (vinyl) Thrax with Thrax (digital) MBL with MBL (digital) Blumenhofer with Mastersound (vinyl) And the Dynaudio Special 40 with NAD needs a mention too. But not compareable. The small TAD was really good too. The Computer Audiophile 1 Link to comment
