Its a big advantage to go after others have already mentioned a lot of
my favorite modules, because I get to add a few more of my favorites
to the list:

A190/A191 - by which I mean that I find the A190 by itself just too
frustrating and primitive, but the A190/A191 together makes for a very
decent Midi/CV interface. I think they should be considered to be a
single module.

A150 VC Switch - The threshold voltage (~3.6V) can be exploited in all
sorts of useful ways - velocity cross-switching, keyboard splits,
delayed modulation (via a slew limiter), comparison logic, etc. Its
also an indispensible companion to the A155 sequencer.

A132 Dual VCA - one of the 4U "small gems", worth its weight in gold.
Too many uses to enumerate, I find myself reaching for it in every
single patch.

I'll also second Martin's nomination of the A165 Trigger Modifier, for
the same reason. It's a tiny gem, and always seems to find a way to
make itself useful.

Regarding polyphony, My A100 is essentially a 3-VCO voice, but I
occasionally use an external CV/Gate source to operate it as two
independent monosynths (one of them will only have one VCO and one
ADSR, of course). I may eventually expand my A100 to support two 3-VCO
voices. But for the amount of money that it would take to buy enough
modules for polyphonic chords, and the amount of time it would take to
manually duplicate a patch for each polyphonic voice, it doesn't seem
worth it to me. There's at least three excellent analog polysynths
currently in production, with good modulation routing flexibility.
There's also several "virtual analog" polysynths available as well.
