Hi Steffen

and welcome on the board ! ,

I think that your LTspice skill is one very good tool for development of modern high performance OTL amps ,

but why your colaboration is limited only with people from Germany,Poland and Czech Republic ? , is some commercial interest the reason ? ,
I think that If You want you can show your LTspice skill and ideas right here on line in this open forum ,
just for example ,and just If You want you can check via LTspice one of the first OTL amp ever developed , model H1 by Julius Futterman , from 1954 or so ,
it will be interesting to see specific characteristics of that simple amp as is...
-OLBW (Open Loop Band Widht)plot
-CLBW (Closed Loop Band Widht)plot
-BW vs OLG (Bandwidht vs Open Loop Gain)plot
-BW vs CLG (BandWidht vs Closed Loop Gain)plot
-open loop output impedance plot
-closed loop output impedance plot
-output power vs load(speaker) impedance plot
-DF (damping factor)plot
-THD spectrum vs output power plot
-Class A operation area vs OPS bias points and vs load(speaker) impedance plot
and so on ...

Best Regards
