My reply never got posted for some reason.

I bought my dad Thiel CS3s, $700 shipped. Not 3.6 or 3.5, just normal CS3.

I will compare to the M22s and keep what I believe sounds better for myself. I don't think it'd be that useful posting a detailed comparison because this is a hard to find speaker, it is about 21-22 years old, but if I get around to it it'll be in this thread.
