I would think Cardas. Magico are very very revealing speakers and Nordost are pretty revealing. The combination is going to reveal the leanest of the Simm.
I’d recommend trying Cardas Clear, Clear Reflection and Clear Beyond. I recommend auditioning for a week each. The sound will be of the same character with a difference in bass and midrange. The Reflection will be be the warmest / sassy and the Clear Reflection most detailed. You should take your time... these should be great fine tuning for your system.
