Doepfer

A while back, I made a rather non-clinical comparison of the Doepfer 
SEM and Wasp filters, along with several others.  You can find the 
discussion here.

I made two comparisons- the first mp3 which is a rather short 
comparison, and then a second extended set later on in the thread.  I'm 
not sure if the extended versions are still available online, as I 
didn't host them myself at the time.  I'll be happy to put them back up 
on my web site if need be.
