The Dipole looks outstanding, but I haven't used it yet. I have QPAS and on occasion it completely blows my mind with beautiful sounds. It really is unlimited and perfect for the "pretty" and ambient side of things. I still have not mastered it so I just haphazardly stumble into interesting sounds.
I've been really impressed with everything I have heard from the criminally inexpensive Doepfer SEM filter. That one is next on my list. I know some of the members here like the Filter 8. It seems very useful in a small case due to the range of duties it can fill. The demos I've seen have failed to interest me much though.
Have fun and good luck.
