Does the DSP8000SE decode MQA fully (ie first unfold and rendering)?

If I see MQA *** on the front panel, does this mean that it not only detected an MQA stream but it is actually fully decoding it? Or is this just showing metadata?

Thanks!

Rendering only, the decode needs to be done elsewhere eg 218, 808v6, 818v3.

Welcome to this forum. Thanks for posting the pictures as wel, very nice and tastefull set up you got there.
Out of curiosity, are you contemplating MQA and or 8000SE's?

Cheers!

My question was for a friend who owns MC600 + 861v8 + DSP8000SE. He tells me that his system cannot decode MQA - even though his speakers say "MQA" on the display, it is apparently not decoding it.

After some digging I read that the "Se" version of the speakers (which he has) CAN fully decode MQA. But the information is unclear as MQA has the first unfold, then the rendering stages.

I would like to know what is it that the DSP8000SE can do exactly.

Me personally, I have a dCS Rossini + Rossini clock. It decodes MQA fully.

Hi,

The SE DSP speakers are MQA renders, the MQA decoding (first unfold) needs to be performed by a suitable Meridian source (e.g. 218, 808.6, 818.3).

Maybe one day the Meridian Sooloos system will be able to do this, but I'd recommend your friend does not bank on it.

I think it's more likely the 861 will eventualy support MQA decoding (which might be limited to DIRECT mode only?), but how long is a piece of string.

Regards,
Carl

The 861v8 cannot decode or pass MQA.


Wonderful perfect quadraphonic sound with distortion levels so low as to make a brave man weep smile

The 8000SE info on M's website is a bit sparse w.r.t. MQA decoding (understatement). There are users who use the 2nd input of the 8k to drive an MQA source bypassing the 861. There is a bit of set up required but it can be done fairly easily with the various MSR config controls and 861 setup (phantom 861 source that calls D2 rather than D1 etc)

So, with your friend's particular setup I would add a 218 into 8kSE D2. The results of full render in the 8kSE can be quite spectacular. If your friend has set up well and is very familiar with his 8k sound then comparisons are easy to do. The difference is pretty clear.

Relative to the $$$8k/861/MC600 it is a small outlay... or at least loan one to test it out.


Rgds,
Nick

What about using Roon to do the first unfold (support for this is imminent) and then playing to the 861v8 via Sooloos connection (which Roon supports)?

Would this work?

My point is: if I deliver first-unfolded signal to the 861v8, and the signal path to the speaker is bit-perfect, the speaker should be able to render properly.

Thank you.

Any thoughts on why the speakers are indicating MQA?

No, they shouldn't be. That sounds implausible.

I guess the input name could be set to MQA.

My point is: if I deliver first-unfolded signal to the 861v8, and the signal path to the speaker is bit-perfect, the speaker should be able to render properly.

The 861 is not MQA aware, so even with it in DIRECT mode, the DSP in the 861 (SPL calibration, base management, room correction) will corrupt the MQA signal, so what comes out is no longer a MQA source frown

It's possible that Meridian will update the 861 at some point, but I'd not hang my hat on it.

The other issue (and I'm not 100% on this) is that I believe the SE DSP will only render MQA that comes from a Meridian SpeakerLink source.

If you friend wishes to feed the SE with MQA today ... then the practical answer would be to add a Meridian 218 between the 861v8 and the DSP SE.

Regards,
Carl

* the 218 has a SpeakerLink pass-though mode, to route the output of the 861v8 to the speakers when the process is used. Otherwise it's the 218 acting as a Sooloos endpoint / MQA decoder that would be driving the SE's.

It's not a great situation for 861 owners at present ... I'm sitting on fence (with my 861v6 and 8Ks) till this is resolved or I get itchy feet and look at other processor options.

Trust that helps.
Regards,
Carl
