Dear Milimetr: Yes, you are right the Jadis performs better through its MM input but in both ways: MC or MM fails/a little short on the bass management.
Even that your lovely speakers can't go lower than 26hz ( I don't know its db deviation at that frequency. ) there is information recorded below that speaker bass spec and certainly the cartridge can retrieval if it's surrounded by the system with that hability. We have to remember that music is formed by notes and harmonics.
As important as is the tonearm to mate any cartridge the phono stage is critical and always makes a difference for the better or worst depends on the phono stage quality level performance.
As a music lover and an audiophile and through my experiences, with " hundred " of different audio systems, IMHO what determine the main differences on quality performance between different audio systems is the audio system owns habilities to play/works in near " perfect " way the bass frequency range, its bass management. Electronics are very important to fulfil that criterion. Of course that speaker/room are important too but speakers can reproduce what the other system links send it to the speakers.
IMHO and due that seems to me that you want a first rate analog performance level you should contemplate as an option a better phonolinepreamp that could make clear justice to your future analog rig.
No one cartridge can shows its " glorious " if through the phono stage this unit is adding and loosing cartridge signal information: I think we need here not only accuracy but neutrality too, to leave the music flow with its natural color and natural " emotions ". Don't you think?
About wood tonearm wand you can choose not only the Schroeder you mentioned but the Talea or Da Vinci to name other options.
Cartridges?, other that the ones you name it exist other top contenders that can fulfil your needs/priorities with different kind of music: Ortofon, VdH, Clearaudio, Da Vinci, Benz Micro, Dynavector, etc, etc.
Btw, price is not the important factor but quality performance level. Not always the more expensive performs better.
Just by curiosity. With those several top graded TT options out there what do you " move " to the Raven's alternative?
Have a good and happy " hunting ".
Regards and enjoy the music,
R.
