    Gavin1977 reacted to Cebolla in Open Home vs UPNP   
    OpenHome (aka UPnP with Linn extensions) and standard UPnP/DLNA are actually closely related (but incompatible) streaming technologies rather than 'formats'. The main difference is that with OpenHome it's the streamer (aka renderer) that owns the current playlist; whereas with standard UPnP/DLNA it's the controller (aka control point) that owns the current playlist.
     
    This gives the OpenHome renderer the advantage of being autonomous with regards to playing the tracks in the playlist once playback has started. It means the OpenHome renderer can sort out gapless playback for itself, allow multiple OpenHome control points on the network to interact with it without any side effects and even continue to play the entire playlist with all associated OpenHome control points switched off.
     
    Contrast that with the standard UPnP/DLNA renderer which is completely reliant on the standard UPnP/DLNA control point for playback. So, the UPnP/DLNA renderer requires the standard UPnP/DLNA control point to tell it what the next track is and where to fetch it from every time the next track needs to be played. This forces gapless playback support to be an interaction between both control point & renderer and restricts the number control points that can interact with the renderer at any one time to one (otherwise you can get strange playback side effects with the various control points competing with each other to gain control over the renderer).
     
     
    Note:
    - Gapless playback is always supported in OpenHome and optional in standard UPnP/DLNA;
     
    - OpenHome renderers cannot be controlled by standard UPnP/DLNA control points and standard UPnP/DLNA renderers cannot be controlled by OpenHome control points.
    However, there are some controller applications that contain both types of control point, so can be used to control both types of renderer: eg, the BubbleUPnP Android app and Linn's older Kinsky controller (but not the newer Linn Kazoo, which is an OpenHome only controller). You can also get streamers with both types of renderer built-in: eg, Linn DS streamers and Lumin streamers;
     
    - Both OpenHome control points and standard UPnP/DLNA control points can access UPnP/DLNA media servers (eg, MinimServer), to get their associated renderers to stream audio files from;
     
    - OpenHome comes with optional built-in support for various extra services such as internet radio, online music streaming (currently only Qobuz & TIDAL) and synchronised multiple device playback (known as Songcast).

    Currently using the Chord DAVE DAC and a DC4, just like @ray-dude in his excellent article:
     
    But I use the DAVE in a DAC mode connected to a line stage with a High Fidelity Cables Pro RCA cable that I quite like and have and a long term loan. Sablon USB from the computer to the DAC. The (unregulated linear) power supply fed a Sablon Prince power cord from a Sound Application TT-7 power conditioner (connected to a dedicate 20A circuit with Sablon King power cord). 
     
    I also have my reference DIY DAC that I've been working on for several years that has parts worth more than the DAVE inside, and I will be switching back and forth between the two DACs in the final stage of tuning.

    OAuth2 isn't a big deal to implement these days (its widely supported by most languages and runtimes).  I have implemented it countless times myself, and in different languages. 
     
    Granted there might be some downstream complications of passing the context between systems, but I doubt these cant be solved problems either.

    Gavin1977 reacted to bubbleguuum in Linn Kazoo - Tidal no longer login in   
    BubbleUPnP/BubbleDS developer here.
     
    TIDAL is now using OAuth2 to login into its service. Before that it was login/password based and that is what BubbleUPnP Server supports as part of its TIDAL OpenHome support.
     
    Linn has implemented the new OAuth2 login method on its OpenHome streamers (and in Kazoo) but not BubbleUPnP Server. So basically the screen that you see is telling you that.
    To login to TIDAL you will need to do it using BubbleUPnP or BubbleDS on Android (select your OpenHome'd HQPlayer as current renderer, go into Library tab and enter the TIDAL folder. You only need to do this once.
    Once this is done, Kazoo will detect that you are logged to TIDAL and you will be able to browse it.
     
    This will work for some time but probably not forever if/when TIDAL removes the old login method, or if Linn remove the old method to access TIDAL (they just removed old method to login for now)
    Adding the OpenHome OAuth2 login method support to BubbleUPnP Server is not trivial as it is rather convoluted. Not sure if/when I will do it.

    You could try IIR, thick warm mid-range. IIR is a bit underrated by my opinion.

    Gavin1977 got a reaction from fds in T+a dac 8 dsd   
    I have not listened to exaSound before, but I have listened to ESS 9038... I don't think it would compare to DAC8 being fed DSD.  ESS chips are not 'DSD Direct', so the sound quality is likely to be similar the PCM section of the DAC8 DSD.  Would still sound jolly good of course.  That's just my understanding.

    We looked at several options, but using a smaller case would not work for fitting all the power supply components, transformer cage, etc. At this point we are inclined to go with a big size chassis. Moving the feet anywhere you want should not be difficult but would require a little bit of DIY (i.e. drilling 4 holes). 
     
    However, Taiko can sell just the CPU coolers for those who want to go with the HDPlex case instead. They would not be the angled CPU heatsinks you see on the Extreme but something easier / cheaper to manufacture, so I expect to be quite affordable. That would be a nice option for people who want something more compact. The Taiko ATX would fit inside the HDPlex. And you would need an external LPS to feed it. 
     
    I am guessing there will be some demand for an external unregulated power supply to feed the Taiko ATX (from people who are not comfortable building their own). Taiko will not get into the power supply business, but I am looking at a few options here as well.

    Gavin1977 reacted to fds in T+a dac 8 dsd   
    Just joined the party ... although rather late. Still I am enjoying the T+A DAC8DSD with DSD512 a lot. I believe that the unit is still improving as burn-in continues. Nevertheless, I am experiencing an amazing SQ when using it together with my OpticalModule/OpticalRendu (after flashing a recent Amanero firmware to the DAC8DSD without experiencing any problems). Also my high-end preamp (Ayre KX-5) seems no longer needed. I get better results when using the DAC8DSD set to fixed line level directly connected to my monos. Although I had tried software control and bypassing the preamp before, now it is for the first time here running extremely well. The DAC8DSD in this setting brings realism in my listening room to a completely new level. I have the feeling that I am listening directly to a live performance as opposed to listening to a good recording thereof. The tonality is spot on, performers have body, instruments the proper size, brass has punch and wonderful texture, ... really stunning. Many thanks to all the DAC8DSD users posting here on this wonderful page that motivated me to get this outstanding unit to my listening room!!!
     
    PS For other potential late comers to the party, I strongly recommend to make sure that you will be testing either a well burned-in DAC8DSD or to be patient to give it sufficient time to burn in. Also the XLR outputs seem to be the recommended setting. Using its on-board volume control I found inferior to setting it to line level and to using software volume control. While DSD128 can be quite nice already, its full magic seems to appear for DSD512 as reported by many others. Oh, and as stressed many times before, its internal PCM DAC is quite good, but it is its DSD DAC that is exceptional when receiving DSD512 material obtained from PCM files upsampled via software inside the computer.

    I thought about using a Hypex SMPS to feed a HDPLEX DC-DC converter, however there is also an additional hitch in that these SMPS are untested in this application and are only used to power amplifiers which obviously only have high transient power peaks.  Providing a continuous 60w+ from a Hypex SMPS might cause it to fail pretty quickly.

    Gavin1977 reacted to Lauritsvd in Chord Qutest   
    I Got a Chord Qutest, and enjoy it a lot.
    It is realy an amazing DAC. 
    Tried a powerbank as ps for the 5v, and liked the better resolution, but the Music was missing some attack, and dynamics. 
    But since it made a difference compared to the stock supply, I wanted to make a better ps. I already had a good expirience with MPAudio ps, and ordered a 
    SLS-HPULN PS With double lt 3045 regulation, and an Audio grade transformer. 
    This is what came out of a few hours of work. The cabinet is from an Old pc. 
    DC wire is Gotham in a 360 layout. 

     
    To my ears, this is just as big a step forward Soundwise, as the Qutest was In the first place. (coming from an Arcam Irdac)
    Very high resolution, lots of attack, but No rough edges, If that makes sense. 
    English is not my native language. 
     Now back to happy listening. 

    There is still room for another powercable, and a better fuse. 
    I even made space for one more PS in the box. Lets see what hoppens next.

    I wish I could do that, but I can't find a way to do it legally. The current plan is to provide:
    a. Instructions on how to obtain Windows LTSC. Someone else is working on that.
    b. A configuration file for Ntlite to remove a bunch of components.
    c. Some scripts that you can run to optimize Windows.
    d. Some additional configurations.
    e. A Process Lasso baseline config. 
    That should do as a start. After that I expect people to tell me how to improve my server :).

    15A on the 3.3V and 5V rails.
    4A on the 5VSB rail. 
    There is also an always on separate low noise 5V rail (limited to 4A) that can be used to power a USB card. I haven't tried that yet. I am still a big fan of a good regulated linear power supply for USB and network, but it would be interesting to try.
     
    16VDC min.
    48VDC max, but I would stay lower than that. 
    Same input connector as the Hdplex - Molex 469920610. 
     
    That is still work in progress, but no, there is no way you can fit the Asus Sage motherboard and the unregulated LPS in the Hdplex chassis. However the Taiko ATX would fit fine. 
     
    Dimensions are approximately 170 mm x 78 mm. 
     
    My unit is a prototype with some manually soldered wires. I don't really want to show pictures of that. Let's wait until I get some photos from Taiko.

    It can do 40A continuously on the 12V rail if that's of any use to you.
    And it's 99% efficient. Depending on the input voltage and the load, it can get up to 99.3% efficiency. In fact the most inefficient component I have in the prototype is the transformer.

    I have one of the first HDPlex 500w units, which has proven to be very decent (though I don't have anything else to compare it to that's not SMPS!).  I dont use the LT3045 outputs mind.  
     
    One of the biggest surprises however is using both 12v outputs (PCIE and CPU EPS) to feed both ATX12v sockets on my motherboard (x570 + Ryzen 3900x).  Instead of placing most of the CPU 12v load on a single rail, its now spread across the 2 rails which clearly results in a obvious across-the-board uptick in sound quality with HQPe running.  It also means I have a good upto 25amps available to the CPU.
     
    And as always for me at least, the shortest cables ATX cables win.

    Now the Taiko ATX module is a product I would be interested in and would purchase.

    Gavin1977 reacted to Nenon in Building a DIY Music Server   
    A suggested list of parts and schematics will be provided to make the unregulated AC to DC linear power supply. It would consist of:
    Transformer —> Rectifier —> Choke —> Filtering capacitors; or to be more complete:
    IEC inlet/fuse --> SoftStart module -->Transformer —> Rectifier —> Choke —> Filtering capacitors.
     
    That unregulated LPS will be tweaked to work with Taiko's ATX module. The output of the unregulated LPS goes to the input of Taiko's module. And we would have:
    IEC inlet/fuse --> SoftStart module -->Transformer —> Rectifier —> Choke —> Filtering capacitors --> Taiko ATX.
     
    The Taiko ATX module has two 8-pin EPS connector outputs, one 24-pin ATX connector and an Auxiliary connector with (+5V and +12V output) for future use. You will need one or two EPS cables (depending on the motherboard used) and one ATX cable to connect the Taiko ATX to your motherboard.
     
    That is the entire power supply. The Taiko ATX is super transparent. Tweaking the unregulated power supply has a significant impact on the overall sound. This is one area where we can tweak things. This is also an area where we can have different versions - a more affordable version and a more exotic version. We can potentially add a solderless option to make things easy for those who like building computers but would like to stay away from soldering. I am sure that would be a popular request. 
     
    This unregulated power supply is something that people can do on their own with parts of their choice. Or use the recommended parts. Taiko would try to arrange stocking the transformer I really liked, to make that more accessible (you have to order hundred(s) to get it). That would be the recommended transformer but you can get whatever transformer you like. The rest is still work in progress.

    I was searching for a PSU and had some experience with Pink Faun and Farad, they are both located in the Netherlands and so am I. So I contacted them to see if they had somekind of solution, maybe a Pink Faun chassis with PSU.
     
    Then Mattijs from Farad told me he was working on a Farad ATX PSU and he had a pre production sample which he was willing to loan to me for a week for testing.
     
    These are the specifications which he provided to me.
     
    Farad SuperATX                                                                                                      
    Full ATX, 5 rail, three transformer double regulated low noise supercapacitor supply with a total of 20 regulations. Gold plated Molex ATX type output connectors according to Corsair RMX connections. The SuperATX has a ground post and ground lift switch. This supply delivers:
    Transformer 1 and Rail 1: 12V/8A on a Molex 8 pin uP connector (max 100W TDP) Transformer 2 and Rail 2+3: 10+14 to 24 Pin ATX connector, all outputs 3A Transformer 3 and Rail 4+5: 3 times 6 pin Molex output peripherals with 5V/3A (total sum 7.5A) and 12V/3A (total sum 3A). One of the 6 pin outputs can be switched to always on for for example motherboard OCXO ultra clocks. Two switchable outputs with GX16-4 connectors (6V, 7V, 7.5V, 8V, 9V, 10V, 11V, 12V) of 1.1A max. The current drawn on these outputs add up to the 12V Peripheral rail max 3A. The build quality is really great and fairly compact, same footprint as the HDPlex ATX 400W, but a bit taller.
    This PSU was sounding much better then the HDPlex.
    More dynamic, bigger soundstage, more relaxed, each instrument had a more accoustic space of his own.
    Every time I switched between the PSU's it was immediately noticable. Really a nice step up.
     
    The HDPlex can quite hot, the Farad stays a lot cooler.
     
    Offcourse all this is to be expected, since the price for this PSU will be around 2.700 Euro's, 3 times more expensive then the HDPlex.
     
    This test proved again to me that a good PSU is very important.
     
    Hope this helps

    I wish it was that simple to explain...
    Every CPU sounds different and has its own character. 
    The 10-core Intel Xeon Silver 4114 has the best and most transparent midrange I've heard from any CPU I've tried.
    The 12-core Intel Xeon Silver 4214 is an overall step down. You would think that as a newer model with more cache and more cores, it just has to sound better. But it doesn't.
    The AMD Ryzen 7 3700x has super nice highs.
    The Intel i9s I have used have really nice body. 
    And so on...
     
    Then every motherboard sounds different too. Take a look at the beginning of this thread. I started with an Asrock motherboard and switched to Asus, because it sounded better to me with everything else being equal. 
     
    How many cores is best - that depends on the OS, scheduling, the hardware architecture, the software you are using, the way you tweak the OS processes, the way you assign affinities, etc. etc. 
     
    Dual CPU over single CPU. Well, that also depends on everything else. Running stock Euphony on a dual Xeon / Sage server did not sound much better than my AMD Ryzen 7 3700x with OCXO clock motherboard. I actually preferred the AMD back then. But the open and transparent midrange of the Intel Xeon Silver 4114 was apparent right away. But then:
    And the dual CPU was quite better. 
     
    Combine all these variations of different motherboards, chipsets, different CPUs, number of cores, number of CPUs, CPU cache, OS, affinities, software player, etc. and you get so many combinations that one can spend an entire lifetime to figure out which combination works best. 
     
    You want to put a meaningful number to each variable? That's also not possible. It's a moving target. You can make the same change on a computer using noisy power supply and the impact may be 5%. That same change on a computer with a transparent power supply could be 90%. And that's without even taking under consideration the rest of the system - your DAC, analog amplification, speakers, power, room, etc. If the power supply does not mask a lot of the music under noise, it can be your room that impacts it. 
     
    After reading this, it may start to make more sense what we are trying to do with this DIY recipe. We want more people to participate in this, and the hope is that it would lead to some new discoveries. New discoveries is the main driving factor for Emile.
    First, the high cost of parts and components would make this less appealing to people who don't have a quite resolving system already. Someone using a PS Audio Sprout 100 with a pair of affordable bookshelf speakers would likely have no interest in building a $10K server. And I would indeed advise them to spend their money elsewhere. The assumption is that those who are willing to spend $10K on a server have very resolving systems already.
    Second, this is DIY. You would need to be able to put a computer together, install Windows, configure everything. That eliminates a huge group of people and leaves those who really enjoy tinkering with that stuff. Yes, some people may decide to build some services around this (i.e. build this for someone else for a fee), and that's perfectly fine. I've built computers for other people in the past and still have learned a lot from their feedback. 
    Third, the power supply recommendation for this build would be as transparent as it gets. In fact, I've never heard more transparent source myself. 
    That means we would have a relatively small group of people with quite resolving systems, building one of the most transparent sources that exists today as a baseline. We all enjoy tinkering with that stuff and as soon as we finish the build, we would be on a mission how to further improve it. And the real hope is that we would succeed and provide incremental improvements. That's the type of discoveries and feedback that would be extremely useful to the DIY community and to the whole industry.

    I think I've answered that before. #2 sounds better than #1. But #1 gives you a real ATX controller. It's a balancing act. 
     
    Appreciate your feedback @Gavin1977. This project is certainly for a very limited group of people. That's pretty clear to me. 
    For a budget of £1500, we don't need Taiko's help. 
     
    This won't be a kit. Taiko is not interested in selling a kit. I am not interested in selling a kit either. If you buy a kit, you would expect to get commercial support. Taiko would not be providing commercial support for this project. Actually, I am going to quote Emile:
     
    It would be a DIY recipe with recommendations for parts, software, etc. You can use that as a baseline or use whatever parts you need to build whatever you want. Or not participate at all.
    What I am hoping to see happening is people building the baseline and improving from there. Think of this as an open source project where everyone can contribute to. No secrets, it's all an open book, and every idea for improvement counts.

    I think it should be affordable... in reality not many will go for a dual CPU option and all those banks of expensive RAM. The budget necessary would stretch into thousands. Those people who can do this might as well buy an Extreme.
     
    A chassis with an integral multi-rail linear PSU capable of accepting and powering single CPU's upto 120w, with dual molex 5v outputs to power a pair of JCAT cards would better fit my bill.  Price £1500?
     
    Perhaps it might be better to view the product as a multi-rail linear power supply, but with the bonus of it including a chassis?
     
    I'm also not against some limited zero noise / vibration isolated fan assistance if it cuts down costs & size.
     
    Go over £1500 and I'd rather start looking at commercial offerings to be honest.
     
    I agree with comments about the enclosure size - 480mm width is a bit too much for most.
