Nope. Domestic Ambisonic decoders have a
Super Stereo mode for "decoding" stereo
sources. They also include a stereo width
control which allows the stereo image to be
compressed to mono-like or expanded into a
horseshoe around the listener.
See the Ambisonic FAQ on my website at:

Wow. That looks really cool. I've only heard an ambiophonic system and
was impressed.
If Super Stereo can recreate the sound that the mics originally heard,
what does ambiophonics do that ambisonics can't?
Does ambisonics cancel cross talk as well (like ambiophonics does)?
I'm assuming also that Super Stereo is not anything like the crappy DSP
modes that one found in cheap AC3 converters about 10 years back,
particularly on Sony equipment (Hall, Arena, Church) where bad reverb
was just added artificially, right?
I have read this 3 times to make sure i didn't mess up or cross the
spelling of ambiophonics or ambisonics (ambiosonics? ambiphonics?
Aminosonic acids?), but i probably did anyhow :")
Thanks,
Bearcat

Cancelling crosstalk make sense only in systems that have
two channels (L,R) and want to deliver them one-to-one to
the two ears (L,R). It's as remote from Ambisonics as a
bread toaster is from a lawn mower.
Ambisonic reproduction assumes that the sound from
each speaker is delivered to both ears in the natural
way, as it would be for a real source, depending only
on the attitude and distance of the listener's head
w.r.t. the source.
Ciao,
