Yep... that is correct. The 218 is either an endpoint (zone) in its own right or it supports the 861 to handle the LR channels in an MC setup.

Thanks all for the help. My friend bought a 218 to put between the 861 and the 8k’s.

Ok. Let us know how it works out.

It is not possible at present, hence my suggestion of adding the 218.
Suppose:
Roon > MS600 > DSP SE

Is it possible to defeat all DSP in the MS600 and thus enable this chain to work with Roon (when first unfold is available)?
Will the SE speaker be able to do full rendering?

Yes, set Audio Output: Digital to "Direct"

As I understand it, currently no: the speaker needs to be "told" to render by a Meridian MQA decoder via SpeakerLink.

That is a great question and I don't think anyone knows yet.

I guess if someone could fire an SPDIF signal from the Tidal desktop app into an SE speaker we might find out.

Essentially, will an SE speaker render from any 1st unfold device ?

As I just posted, I have been told "no", because it was never envisioned that renderable MQA would ever be output unencrypted over SPDIF. In other words SE loudspeakers were always envisioned as part of a SE + 818v3/808v6 (and subsequently 218) system.

It wouldn't surprise me if this situation changes at some point.

Perhaps Roon could do the "telling", and that could be passed through the end-point "Direct" to the SE speakers over SL. Is that at least possible in theory? Whether or not it will work that way does seem to be unknown. What a nice present it would be.

Not going to happen, I'm afraid. For one thing, the MS200 and MS600 don't support MHR.

*IF* you have a renderable SPDIF source, you'd still need a firmware update in the speakers so that they can recognize MQA by themselves.

Are there actually any post-first-unfold renderable MQA SPDIF sources out there? Would need to connect one to a 218 or 8x8 to check.

@Joel,

I tend to agree that the situation for SE may have to evolve beyond the original cope.

If MQA can be unfolded and/or upsampled to 88/96 then I would think this must be viable as a digital output in order to get into DACs that are renderers. Unless of course that is via USB only.

If so then a USB to coax conversion would be needed.

PC's can output SPDIF over coax or optical. I used to feed my G68 with such a source.

Ironically I might imagine M selling more DSP units as standalone systems if they did either fully decode or at least render on receipt of a 1st decode signal.

Not trying to draw your specific Roon view here, but, it must be entirely feasible at least technically, for Roon to send whatever MQA meta info is needed for input to an SE DSP to render (if that is not already part of the embedded signal)


Rgds,
Nick

As long as there isn't a whitelist of renderer USB IDs... I'm not saying that there is, because frankly it would be unmaintainable. That said, there *were* some issues with early versions of the TIDAL desktop app in that it didn't recognize my 818v3 as a renderer, but it did my Explorer²; which suggests that the TIDAL app was checking USB IDs for a time at least. Whether it was doing so from a "trying to be helpful" perspective or other, or whether it was something else entirely, I have no idea.
