There is an increasing number of AES67 devices being released to market, that seriously address spatial audio in the life context. The new Merging technologies Merging+Anubis interface is an interesting example which is networkable up to 256 channels that provides a range of onboard monitoring options for spatial audio and promises in a forthcoming firmware update real-time and Masonic decoding up to seventh order.

Other examples include a line of technology from Klang, such as this one, which provide monitor mixes for multiple musicians for 3D headphones.

Klang also have an 8 channel break-out box which looks like a good balance between other offerings listed below

There are also a collection of differing analog outputs and mic-pres etc - for an ambisonic dome rig one would want at least 24 analog outs to speakers

AtteroTech have a 32 channel solution for balanced XLR. I like their smaller 4 channel AES67/Dante-Analog solution (unD4O) - one could have a number of these dotted around a dome which makes for shorter analog cable runs. Or if more channels are needed perhaps the und32, 32 channel single unit,
