  1. Hi, Thanks for answering. For the time being, and waiting for the release of the next version of AO, I would be happy to restore the state the machine was in prior to installing and running AO3.0. But even the restoring script needs a valid licence, which has been void by installing new devices/cards on the computer. So I'm a bit stuck with a machine which I am not able to optimize, neither to restore to its original state. Can you please help ? Thanks, Best
  2. Hi, I installed hardware extensions on my machines which changed the hardware identification. Is there a clean way to remove the installation of AO3.0 and restore the services in the state they were before using it without buying a new licence for this sole purpose ? Thanks in advance.
  3. Probably somewhere in the Settings -> Audio -> Device setup You will find something that looks like that. The Resync Delay should be the subject of your question if I'm not mistaken.
  4. Before I discovered PGGB, I was contemplating upgrading my DAC to a Tambaqui. I asked some friends who are equipped with a Tambaqui to test the PGGB files and they did not report any improvement which is not very surprising knowing that this DAC operates an internal upsampling to 3.125MHz/32 bits. But I am so impressed with the results I have today with PGGB files on my Gustard x26-Pro that I am tempted to challenge my previous decision. Has anyone had the opportunity to compare a Dave fed with PGGB files with a Tambaqui ? Thanks in advance
  5. @Zaphod Beeblebrox When HQPlayer was released in the native version of code for the M1 processor of Apple (arm64 version), I noticed a very significant improvement in speed over the Rosetta II version. Do you have any clue when the native version of Mathlab will be released on order to allow same significant improvement to be brought to PGGB running on the this M1 Mac architecture ?
  6. Hi Shorty, In response to your question, both are fantastic delta-sigma DACs. The SDA-6 has been designed by Singxer with the idea of using the NOS mode of the AK4499 ship in connection with HQPlayer. The x26-pro is a more classical interpretation of a DAC though it is equipped with some interesting features like the double DAC chip (one for each channel), a double power supply (one for the digital part and one for the analog part), aso… Both have a fully discrete output stage. I am mostly listening to acoustic music, a lot of strings, voices, chamber orchestra, jazz aso. I have a limited exposure to amplified music. I have a strong bias toward details and micro-details restitution. My system is very transparent (acoustically treated listening room, B&W 802D3 speakers, Benchmark AHB2 or Coincident 25th Anniversary mono bloc amps). Both DACs are connected directly to the mono blocs. No preamp at this stage. I am using HQPlayer as a platform, whether upsampling or not. In case I play PGGB upsampled files, I use HQPlayer in completely transparent mode. Otherwise, I use HQPLayer to upsample and/or convert music format. I am using Diretta to reduce the noise of the USB inputs of DACs and, on the SDA-6, most often an SU-2 in front of it. Having said all this in order to precise the context of my description, I observe: A very transparent and smooth restitution with the SDA-6. The combination of HQPlayer and the SDA-6 is working exceptionally well, especially in DSD, where both excel. A special mention to the justness of tones and realness of instruments compared to real life concerts. My SDA-6 is able to play DSD 1024 with the SU-2. So I have the choice between various modulators of HQPlayer and various resolutions. A slightly more precise presentation of music with the x-26 compared to the SDA-6. Dynamics and micro-dynamics of music, vibrations and micro-vibrations of strings and voices are rendered with more liveliness which make the listening experience more vibrant, more engaging. The more so that the x26 is capable to read 705.6 or 768 kHz files, which my sample of the SDA-6 is not able to, even when used with the SU-2… Using PGGB upsampled files makes the listening experience even more vibrant IMHO. In summary, given my personal tastes, I have slight preference for the x26-Pro. Adding to that the X26 has an integrated preamp, which allows me not to use HQPlayer’s volume. This personal opinion should not, in any case, degrade the image of the SDA-6 which is a fantastic DAC in connexion with HQPlayer. Hope this helps.
  7. If you look at the very bottom of this page, you will notice that A22 is specified for up to 768 kHz on the I2S/USB inputs. http://www.gustard.cn/?post_type=products&page_id=8942 Hope this helps.
  8. Just wanted to share my appreciation of this technology and of the quality of Zaphod’s support. I asked for a trial licence on Sunday, and was happy to receive it straight away. Zaphod asked about the DAC I had and underlined the fact that the Gustard x26-Pro would be a good candidate to appreciate PGGB. I was sceptical and expected no significant difference between the 16fs capabilities of the x26-Pro compared to the 8fs capabilities of my Singxer SDA-6. I was also expecting that processing files in 24 bits would be enough and that I would not need 32 bits. Zaphod took the time to explain with a great length of details and his genuine skills why I would be better trying 32x16fs and compare with 24x16fs or the like in 8fs with the SDA-6. And as hopeful as I was that I could spare some storage space going for 24x8fs, I have to admit that 32x16fs makes a big difference in the resolution and the airiness of the treble on my system. And PGGB really is a game changer even for “modest” DACs such as the Gustard x26-Pro. So thank you Zaphod for having brought this technology to us, and thank you for your support.
  9. Hi, I made this transformation some years ago. To the best of my knowledge, the MC-3+USB does not need 3A. It is important to not go above the 6.2v which are requested, but you should be fine with less than 1A.
  10. Hi Simon, Friends of mine have tested the 3D-Lab Nano player connected in I2S to the SDA-6 and they were thrilled by this combo.
  11. Yes. But as I tried to report, the competition was not fair. In the sense that the SDA-6 and x-26 were fed with a music flow which was not optimal, as far as I understand what is optimal today. My best guess is that upsampling with HQPlayer, or with Aurdirvana as @DomiJi suggests, is optimal to make the best usage of the NOS possibilities of this DAC. And, as I explained, and this is my belief, respecting the original format of music, is very important to preserve the micro-dynamics of music. I have a lot of respect for the work achieved by Jussi with HQPlayer. But my experience is just different at this point.
  12. Roon is running on my NAS. HQPlayer on my Mac Mini M1.
  13. Has anyone tried off-line upsampling, like PGGB, in connexion with the SDA-6 ?
  14. Thank you for sharing your experience. Yes it's interesting to notice this kind of synchronisation between our respective quests. I might give a trial to Audirvana again and thank you for pointing this out. I have to confess that I have a personal affection for the solution offered by HQPlayer alone. Thanks anyway.
  15. A few weeks ago, Nicolas, a neighboring audiophile friend, came over to the house to let me play with his source: an Emerson Digital network player, an m-Scaler upsampler and a Chord Dave DAC. It turned out that its source gave an uncompromising lesson, especially in the micro-dynamics of music, to the ensemble that I thought was particularly well-groomed, consisting of Roon + HQPlayer, Diretta, and one of my DACs, either the Singxer SDA-6, supplied with I2S by the SU-2 interface, or the Gustard x-26 Pro. As he himself explained on my thread, listening to dynamic music, ie amplified, he lacked this desire to dance, to stamp his foot, in short to celebrate with movements of his body the life that goes with the music… After he left, I was keen to try and figure out what was going on. I started looking on the convolution side, blaming this process that I had been using for a long time anyway. By removing the convolution, I was able to replace Roon + HQPlayer with Audirvana, and found all the musical micro-dynamics that I had felt with the source of Nicolas. The DACs themselves were not involved, it was the digital music processing process that was involved ... However, I was not completely satisfied, because if Audirvana offered me a solution for the PCM format, which I could up-sample to PCM 384 or 768, I was stuck in DSD and could not take full advantage of the NOS mode of my SDA-6 which has a strong preference for DSD 256 or DSD 512… It was frustrating… Following this experience with Audirvana, a first conclusion quickly emerged: converting the PCM format to DSD, even with HQPlayer, really damaged the dynamics of the music. As @Le Dom kindly confirmed on the Diretta thread, it felt like listening in a Pullmann comfort, but not listening realistically. With @Patatras, we have multiplied the experiments, until trying HQPlayer alone, in upsampling, in [source] mode ie respecting the original music format, upsampling the PCM formats to PCM 384 and the DSD formats to DSD 512, but without using Roon. And things really took came together, each on our side: the SDA-6 and HQPlayer were made for each other, as long as HQPlayer was used on its own ie without Roon. In PCM format, we thus find all the dynamics offered by this format, without any concessions. In DSD format, we find all the tonal accuracy and transparency, all the openness in the treble, offered by this format. As @Patatras and I both use an SU-2 as input to the SDA-6, he suggested to me to change the power supply of the SU-2, which I did by purchasing a small adapter from Kitusne HiFi, which allows me to power this box directly from a 5v rail of my Paul Hynes linear power supply. Thus equipped, the SU-2 gives the full measure of its capabilities, still offering a more pleasant opening in the treble. Finally, let us specify that Diretta is a very appreciable addition to this set. Set in "Sync" mode to respect the dynamic character of the music, it offers additional airiness and appreciable openness. All in all, I am confident to welcome again a confrontation of my SDA-6, powered by HQPlayer in [source] mode, Diretta in “Sync” mode, and to confront the best DACs on the market, even if they are much more expensive. Without claiming that this experience applies to all systems, it seemed important to me to share my conclusions with you: when I bought my SDA-6, I did so on the testimony of an industry expert who praised the advantages of the NOS mode of the AK4499 chip. I have done well, it seems to me, to follow this advice. HQPlayer offers this SDA-6 a truly ideal platform for producing quality music. Thank you to Singxer for offering us this product at such competitive conditions and thank you to Jussi Laako for offering us HQPlayer as an upsampling platform to serve this DAC ...
  16. The last one of what ? T90 or SDA-6 ? I had questioned Liter from Singxer earlier this year about the incidence of AKM fire and he had mentioned that they had some inventory of AK4499, enough to face demand as they forecasted at this stage. Re T90, you might have noticed that they will release a new version, the T90SE, based on ESS9038Pro this year. The prototype of this DAC shows absolutely stellar performance based on measurements: https://translate.google.com/translate?sl=zh-CN&tl=en&u=https://www.l7audiolab.com/f/topping-d90se-dac-prototype/. Remains to be seen how it will sound in production...

    I noticed a mention of the volume being mounted "read-only" in the log file. I mounted the volume with "read and write" permissions and this solved most of the problem. Not sure why. Also, I still have some .wav files not recognised, for an undefined error: # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-01-Diana_Krall-Like_Someone_In_Love-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-02-Diana_Krall-Isn_t_It_Romantic-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-03-Diana_Krall-L-O-V-E-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-04-Diana_Krall-Night_And_Day-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-05-Diana_Krall-I_m_Confessin_That_I_Love_You-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-06-Diana_Krall-Moonglow-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-07-Diana_Krall-Blue_Skies-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-08-Diana_Krall-Sway-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-09-Diana_Krall-No_Moon_At_All-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-10-Diana_Krall-Dream-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 # 2021/05/18 16:14:43 clReadWAV::Open(/Volumes/Music/Original Music/Qobuz/Diana_Krall-Turn_Up_The_Quiet/01-11-Diana_Krall-I_ll_See_You_In_My_Dreams-SMRP.wav): clWaveIO::Open(): clID3frame3::clID3frame3(): insufficient data: Undefined error: 0 Any idea ?

    Thank you for your reply. I will double check, but I have no problem playing those albums from Roon or Audirvana. Albums were purchased from Qobuz and downloaded in AIFF format, like other albums I am purchasing there. Any other idea ?

    HQ Player

    Hi, Recent developments have driven me to reconsider the usage of Roon and try to use HQPlayer on its own. I am busy looking at HQPlayer Library which I never investigated before. My music files are sitting on a NAS on my network. I noticed that some of my albums have been perfectly identified by the scan while some others, sitting in neighbouring directories, have not. I repeated the operation 2 or 3 times without success. Are there any specific recommendations I should be aware of setting up this part of the application ? Is there any way to debug the behaviour of this feature ? Thanks
  20. I valuate your opinion. I personally have a preference for people who judge after having tried than people who make "theoretical" evaluations based on their beliefs. Having experienced this product, I can say that it delivers what it claims and that it is worth a trial. The fact that the people at Diretta's do not want to participate in this forum is, IMHO, just an assessment of the size of their team, which is small. Also, please bear in mind that their main market is OEM and that discussing with private individuals like us is not their business target. Just my 2c :)
  21. Hi Wolfgang, Congrats on your acquisition :) I personally have a preference for the AMSDM7 512+fs and DSD 512 when running this DAC. But I am also very happy with ASDM7EC and DSD 256.
  22. You might want to check this DAC: Apart from a different chip (ESS9038 x2 instead of AK4499), it has a lot of similarities with the SDA-6: - NOS mode to make the best out of software upsampling (HQPlayer for instance) - high precision clock with the capability to synthesise a 10 MHz external clock if desired - full discrete analog output stage with volume control - similar price range
  23. Yes it works with the PLL locked by me. No problem detected.
