  1. 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
  2. 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.
  3. 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
  4. 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.
  5. 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.
  6. 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
  7. Roon is running on my NAS. HQPlayer on my Mac Mini M1.
  8. Has anyone tried off-line upsampling, like PGGB, in connexion with the SDA-6 ?
  9. 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.
  10. 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,
  11. 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 wil

    HQ Player

    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/Dian

    HQ Player

    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 ?
