Well, I got burned out looking at all the filters. Was overwhelmed quite frankly. For me came down to the SSL and Qpas, granted Qpas isn't a filter module in the strict sense of the word. I think for filter power SSL and similar, were all extremely powerful. But I went with the Qpas. I just like the sound design possibilities. Make Noise wanted to make it fun and inviting to experiment. I took the bait. Maybe down the road I'll look at other options. I'm fairly new to eurorack. I have the Wasp, and enjoy it. I like Doepfers filters as they work as advertised and are relatively inexpensive. So it'd be no problems adding some of their filters on the cheap. Thanks to the contributors.
