Hi Chris,
FWIW, the entire new 800 series now uses a 1st order cross over.
I have never heard Merlin speakers.
I have no idea if the S805's are suited to one design over the other, BUT the DK amp is not a low powered amp, it is 160 (?) watts and does not lack in power. The rest of your question can only be speculation and one could only know by trying each set up.
I will say this, the S805's for me (w/the Classe) have been the best speakers I have ever owned.
