Thank you Chris for taking your timeā¦
I think all is explained by the level of your equipment. Probably the level of excellence is so good that you do not notice any improvement. It happens also with a very basic setup. Mine as you see is a medium (-) setup and thatās why I hear a welcome improvement when I upsample with HQPe. With Roon upsampling the improvement is marginal. Thank you again and enjoy your magnific equipment. Cheers.
When setting this up USB, should we use ASIO or WSAPI? I get the MQA192k on the top right screen of TV but it says 96k on front of 205. Also not sure Iām getting the full unfold unless I use the WASAPI driver. I get the smaller purple dot and not the larger star blue dotā¦Any help would be great. Yes updated USB and main firmware.
I am sorry for not responding sooner, but I want to close this topic.
Long story short, I wasnāt doing anything wrong or had any incorrect settings. With the help of @Chris_Kimmelshue, I got the settings right. The reason the MQA was not displaying is because my OPPO had a non-standard Bang&Olafsen firmware (donāt ask how, I was a victim of a clueless dealer).
So when I got my second OPPO 205 from OPPO Digital from the last batch, the MQA worked immediately with the standard US firmware.
So in the end, I sent the other OPPO back to California where they re-flashed it with the correct firmware.
OK so what are the real settings for MQA to play natively? Iāve read different ways and Iām still confused on which settings to choose. Any help would be great!
With its latest USB DAC firmware it should be a Full MQA Decoder via USB input. So set MQA Capabilities to āDecoder + Rendererā to see if it works.
Yeah I did that but Iām not sure which driver to use, WSAPI shows blue bright dot and MQA Auth and ASIO only shows purple dot with no MQA Auth. Is WASAPI the prefered driver for MQA?
Does anyone have a screen shot of their settings showing MQA with Roon/Oppo 205?
Ok so this looks like the WSAPI driver and yes I use this when in MQA only but is this the preferred method? All my other listening is done in ASIO so that I can up-sample to DSD512. Roon will not go about 384K for some odd reason with the WASAPI driver.
Chrisā¦could you please send me the link to fix the XLR output on the Oppo UDP-205? I have tried to private message you, but my message is not being sent for some reason. Thank you in advance!
What firmware (for both the Main and USB boards) are you currently using? The link I have is for the beta firmware (that you are welcome to), but now that firmware version is official.
The latest HDMI/Main Firmware is UDP20X-60-0625
The latest USB DAC Firmware is USB-0118
The main firmware installed is UDP20X-60-0625, which is current.
The USB DAC firmware is USB-0118, which is also current.
However, I cannot get the Oppo player to output an XLR signal greater than 48KHz, as indicated on the display as āMQA Studio OFS (48KHz).ā This occurs when I am playing am MQA file from Tidal masters, which I know is a 96KHz file after being decoded by Audirvana. Just as well, when after being decided, an 88.2KHz signal is displayed as āMQA Studio OFS (44.1KHz).
All upsampling is turned off. I have tried using Audirvana as the decoder and the Oppo as the renderer. I have also tried using Oppo player as the decoder and the renderer. Regardless of which way I do this, the result remains: nothing higher than 48KHz.
Have you any other ideas regarding this issue? Also, after the MQA Studio that is displayed, what does āOFSā stand for? Is it output sample rate? If so, itās a good guess lol.
But any help/suggestions would truly be appreciated.
Peter, I understand what you are saying. However, I have seen other OFS signals at least at 176.4 (corresponding to 44.1 signal), 192 (corresponding to 48), and all the way up to 352.8. These higher values represent what MQA offersā¦a double unfold of the smaller 24/44.1 or 24/48 file to produce at least 176.4 sample rate, at least of what I have researched regarding the MQA process.
IMO, it seems as though it is getting the decoded MQA file, but the rendering is not happening. Am I on the right track?
I am not sure if this is the issue Ryan, but there is a lot of MQA out there whoās target resolution is 44.1 or 48, so there are times when that is what you will see when properly rendered, despite the first unfold producing 88.2 or 96k streams. Apologies if I am stating the obvious but people do get tripped up by that.
āEDITEDā
I also have Ultrarendu and Oppo UDP-205 with DAC with firmware 0118. I have a somewhat similar and somewhat different issue. Havenāt noticed it until I upgraded to latest Roon 1.6. Have you figured out anything new around your issue or have you figured out any way to resolve it?
Iām using sample rate conversion to DSD 256.
With MQA I used to have 2 issues with Roon --> Ultrarendu --> Oppo 205 setup
Issue1:
I used to have headroom -4db enabled in Roon but it causes problems for Oppo MQA because Oppo doesnāt seem to detect core decoded streams and hence doesnāt enable rendering. It was a pain to enable and disable headroom for MQA playback only. I managed to work around that issue by disabling headroom and using -4db setting in sigma delta phase in sample rate conversion settings. These headroom settings donāt seem to make any difference in distortion scenario (Issue 2).
Could there be an option in headroom settings that disable it for MQA material?
Issue2:
After playing MQA (at least 96) the sound is distorted and the BBM of the playback is in another ballpark when playing non MQA content afterwards.
Settings for the reproduction (can provide more if needed):
Oppo sound upconversion disabled
Roon conversion DSD 256 -3DB
Reproduction steps (easy):
Start to play Tidal MQA 96
Switch to cd quality local file --> plays a lot faster with metallic distortion
Switch roon DSP conversion on and off fixes the issue immediately or eventually
If you restart Oppo instead of 3) you start to get gaps in playback
Restarting Ultrarendu doesnāt make any difference
