Hi Fons, is this using your own calibration for both microphones?

Hi Fernando !

Hey, good to hear from you...

How are things over there ? I've been home-officing [2] for the
last three months, which in practice means I'm more or less doing
whatever I want.

Same here, home-officing as well, a few short trips to ccrma to pick up things or first stuff that cannot be done remotely. Not really doing whatever I want, though (well, a little bit :-). Been working on (trivial) stuff for our weekly streaming online concerts / jam sessions (the "Quarantine Sessions", up to #14 this coming Saturday, see ccrma's web site). Some SuperCollider code to "spatialize", reverberate and control them remotely and then feed the ambisonics 3rd order mix to a binaural decoder and mastering processor for the remote audience :-)

I measured the SPS-200, and two Ambeos [1].

At home?? I imagine this was pre-covid?

For the Ambeo I also
measured the IRs of their plugin. The two measurements are almost
identical, and they more or less (apart from some gentle EQ) match
the plugins IRs.

Good to know. I have to re-start my measurements (curious about the Zoom), there is just too much to do. But as I am at home I don't know if it would be worth it (smaller rooms, so shorter ir's - at ccrma I was down to only about 200Hz already)

[1] One of my Chinese bosses (management type) insisted that we
should investigate the combination of binaural and Ambisonics
by putting an Ambeo close to the left and right ears of a dummy
head. Wasted a lot of time making some recordings that way.
Then asked him how to proceed. No answer. Then Corona arrived.

[2] Every noun can be verbed.

Ciao,
