Steingraeber transducers in action with Pianoteq

It says it right here on this Steingraeber site: https://www.steingraeber.de/en/innovationen/transducer

... The startlingly-authentic grand piano sound is thanks not to out-dated sampling techniques, but to the physical modelling approach of piano sound ‘Guru’ Philippe Guillaume and his firm Modartt/pianoteq.

I am a bit doubtful though about the sound of pianoteq played through a transducer on the soundboard. Don't we hear a modeled soundboard with its proper modes played back on the physical one, not a linear device for sure? Unless there is a special version where the soundboard response is absent from the model, or is properly equalized, I still think pianoteq sounds much better on normal speakers or headphones, (in my opinion of course)...

Of course, only pianoteq can be so powerful with microtuning in real time...
