The Meridian Explorer E2 has an issue with it’s MQA implementation where it does not handle already decoded MQA streams correctly to perform the final unfold and rendering of the content. For the Meridian Explorer 2, I would recommend leaving the MQA capabilities to “Decoder and Renderer”, as this will get you the best performance for your device given this quirk. When you are not using DSP, the bit-perfect MQA stream will be sent to your device for full decoding and rendering. When you use DSP, the device will receive the decoded MQA stream which is still a high resolution file.
Meridian is aware of this issue and hope to be able to release a software update to improve this behavior.
This gentleman is doing Roon up-sampling to DSD256 and still seeing MQB on the same DAC’s screen - hence my confusion
I personally don’t care myself since I don’t have an MQA DAC but my old man is obsessed with seeing MQA or even MQB on his DAC’s screen, and is not seeing it the way the gentleman above apparently is, with Roon up-sampling.
So by MQA signal carrying through, it’s not for further rendering that the old man wants after Roon 1st unfold + Roon DSD up-sampling (obviously) - it’s just for the MQB logo to pop up on the DAC’s screen.
I’m a little confused: with an MQA DAC, can you unfold, apply DSP in Roon (such as Headroom management), and send the DSP’d stream to the DAC with the MQA rendering information so the MQA rendering is applied to the stream that’s been DSP’d? I’m asking about DSP functions that aren’t upsampling per se.
Yes you can. All you need to do is tell Roon what your DACcan do (it will almost always know) and leave the Decoder on. That means most times, do nothing. If you don’t do any DSP in Roon then it will pass everything through. If you do DSP (excep upsampling) then Roon will software decode and pass Rendering info on. If you do DSP upsampling in Roon then Roon will software decode and upsample but won’t pass 9n Rendering info because Rendering is upsampling and you’re doing it in Roon.
Most times, you don’t need to do anything. Roon will pick what is best.
Great update.Roon is getting better and better. I’m greatfull by the effords you Roonguys put into Roon. After 9 month using Roon I can’t imagine a life without, so I will upgrade my mebership from annual to life soon. Keep up the good works!
(The truth is out there but not necessarily here)
I’ll give that a shot. I do like that DAC and it is nice for the price, for sure, and it also gave me 6 months of MQA I wouldn’t have had, until Roon 1.5. But I have not found that it sounds as good as the DACs at the $100+ price point (for obvious reasons…no I don’t expect Champagne at Bud Light prices). What I wonder, though, is whether the firmware/filter issue with MQA isn’t making the non-MQA content on the S2 sound comparatively worse. A DAC that is only good with MQA isn’t that good. They gotta fix that!!
