I really like the Ladik in- or outputs like the Ladik A541 (I have 3 dual inputs (A545) and 1 dual output (A540)).
But I prefer not to use them as end module.
I use it to interface other gear (2 semi modular synts both stereo outputs, and 1 effect box dual in/dual out), but not as final output module (to an external amplifier or mixer).
For that purpose I took the Rosie in combination with a Pico DSP, the Rosie has 2 inputs (1/8 mono: eurorack level) and 1 output (1/4 stereo line level) and a headphone (1/4 stereo) output.
But it has also a send (mono) and return (dual mono) which pairs well with the Pico DSP.
The only thing I encountered is that both channels take the same amount of processing (by the DSP) so I don't have the possibility to mix processed signal with another unprocessed signal.
Then I need to put the effect between the mixer/VCA and the Rosie.
A nice option for movement in LFO's is the Batumi.
