I have never heard Marten speakers but they came to my attention recently and I will have a listen to their smaller products soon.

Lenehan Audio ML1 or ML2 reference. I am currently in an apartment, so I have my ML2's in storage. I have my ML1's on springs for both sound quality and it decouples them from each other and the floor. Helps keep the neighbors happy :-)

They sound great with upgraded Prima Luna Dialogue Premium HP,

There are many reviews, like:

If you want to know more, or who nearest you may have them?
Ask Mike which recording studios use them, and the older ML1 vs Magico Mini's in NYC. I don't know of more recent comparisons, sorry.

There is probably no "direct" answer as a soundsystem has to be seen as a whole, including the acoustic characteristics of your room and your personal tastes!
I love the Dynaudio Contour 20 on my friend's Krell KSA-100s amp + KRC3 Preamp, Ayre QB9 DAC.  Il like my Ryan R610 coupled with my Rega Elex-R amp + Rega DAC-R.
