Doepfer

Well if you want the CEM sound then clearly only a CEM based filter will do. 

I also have a S1mk2 and love its 2/4/6 pole high pass filter. It is voltage compatible with the Doepfer/Eurorack standard - don't keep them apart! I tend to think of the S1mk2 as a giant Euro module instead of a separate system. 

People who have used the S1mk2 and the MMF-1 say they sound different FYI. I too assumed they would be the same.
