Thanks all.  I guess I was misunderstanding the VCAs!

I still think it's weird that the a120/a106-5 filter it without amplification.

An a119 and the a133 are both on my wishlist.  The a133 especially for
use with my BBDs.

I have an mf-101 en route and am looking forward to the envelope
following fun.
