The titel is pretty self-explanatory. I just returned to ROON and got myself an iFi ZEN Dac for MQA playback over TIDAL. But on several live albums (Ayreon - Ayreon Universe Live, Ayreon - Into the Electric Castle), I have very annoying half-second glitches between tracks when playing back the MQA versions from TIDAL. This does not happen with local files or local MQA files. I am on a steady wired 150Mbps Ethernet connection with Google DNS set. I hope somebody here can help me :-(, since MQA playback over TIDAL with the Zen DAC was more or less one of the selling points of coming back to ROON…
Just moved my iFi Zen DAC to the Mac Mini (core) and yeah, issue is still there. Kind of a bummer but oh well. I have two outputs from the Mac Mini… the iFi Zen DAC goes into the 7.1 analog inputs (just front right and left channels) to basically bypass the Marantz DACs… and one optical into the Marantz which gets me up to 192kHz. So I’ll have to live with switching to the “optical zone” if I want to listen to a gapless album and forego MQA.
Appreciate if someone from @support could please reply. This makes the listening experience sub-par for full length MQA albums using the iFi DAC which is my only device for desktop listening. I have also raised a ticket with iFi but I am not sure where the problem lies.
Can you not try it with the Tidal app and the mac and see if it’s the same? If not then it’s Roons comparability with it perhaps. But I think i it’s if implementation and the fact they are using Burr and Brown DACs that don’t have MQA processing built in like the new wave of DAC chips , they treat MQA as DSP as far as I could get from their support, they scooted around the question without really answering when I had dropouts with Linux and MQA.
Just played an entire MQA album on the TIDAL app on my Mac and not a single dropout or muted track. So the Neo iDSD definitely handles MQA properly. Its something that Roon does with the DSP processing on a MQA track that somehow confuses the DAC and causes it to go all silent. I have Headroom, Crossfeed, Audeze Preset and DSD upsampling enabled.
Listened to the same album on Roon with all DSP turned off and the DAC both decoding and rendering MQA. Again no problems whatsoever. So I think it’s obvious that DSP on MQA is what is causing the problem.
Think the issue is specific to the iFi Neo iDSD and maybe some other DACs from iFi as well. At least I have no way of knowing otherwise but definitely does not occur when playing on my Oppo UDP-205 USB Audio.
