Looking for a 5.4 system at most and I'd like to work with AES/EBU which googling suggests Meridian's digital connectors output that.

Does optical in from a TV send out a surround signal always or would new videos have DSTX and not have a surround mix they can send over optical?

Am I understanding correctly that Meridian devices like these can output to Genelec 8260 monitors digitally to avoid the extra AD conversion, while also outputting to two analogue surround speakers, and a subwoofer?

Chain would be optical>Meridian>Genelec AES, Kali RCA, Minidsp HD>2 to 4 subwoofers.

I can get a mint condition G91 that also has a CD player which I'm also in the market for... Can it do all this?

Can't find anything else for around $2000-3000, and all surround processors reviewed here seem to be trash, so I'd like to keep everything digital for the main two speakers... Not sure if the Meridian can handle a 4.1 system if I don't have a center.

Any help is appreciated.

Check if the digital outs really provides what you need . I use an G68J and the HD621 coprocessor (to get HDMI inputs ) and 3* Meridian DSP5200 digital speakers + 2*DSP3000 .

I've heard of people using The meridian HD621 coprocessor only, with Genelecs so it should work .
The HD621 can split HDMI to 5.1 digital outs (there are a new such processor that probably has more than 5.1)

The Caveat can be how it handles HiRes source material all Meridian Processors and speaker uses a special protocol called MHR thats encrypted over its SPDIF outs .

I think the digital out of for example the HD621 can be configured via the setup software to be normal PCM outputs maybe its also possible with the G68/G91 ? But some limitations may apply....

Such as when not using the MHR protocol you be truncated to 48kHz or something ? Because basically no one is actually allowed to split out the hires audio of HDMI stream to separate digital outputs. Just like the spdif/optical of your SACD/DVDA machine odes not provide hirez ( a Meridian DVDA does but over 3*SPDIF with this MHR protocol )

Do visit the meridian forum these guys know so much more than me on the subject .

If you only intend to use non HDMI sources your may be fine ?

I'd be feeding it from optical.

I'd be referring to this when making cabled, that use Speakerlink connections but three of the pins can be used for AES:

Or I could use the coaxial toslink connectors I think with an adaptor that adds resistance.

Thats nice to see :) time to reconnect with the meridian forum .

The newer speakers and later processors use these speakerlink via ethernet . If you get an older processor like my old G68J it only has spdif/MHR and you dont even need to build conversion cables

Ahh ok I get it. my statement above applied to a newer processor with the Ethernet speakerlink ports. I know nothing about the older ones, but I can confirm that spdif, analogue, and speakerlink on my processor are all live at the same time for output.

I am fairly certain you can make the Meridian processor work for your purposes. It’s really quite versatile if you’re willing to do a little configuration.

another similar option would be a properly configured Theta Digital Casablanca (used off eBay they can be cheap). Likewise not an easily configured consumer product, but absolutely flexible in the hands of a nerd, the dedicated, or a pro installer.

The people on the Meridian forum do have answers to a lot of things so its best to ask them.
And prior art ? have anyone else done this ?

I tried to see what could be done in the M-config (Meridian configuration program for their processors ).
You can not select other digital speakers than Meridians own in the setup for speakers hopefully that is not a problem.
