[sdiy] Looking for 2164 12db/oct slopes bandpass filter design.. more detailed..

[The Old Crow]

   The main reason was poor SNR.  I tried 13700s back in 2001 when the 
first 480 was being designed. Much noisier than the CA3280 which itself 
wasn't terribly quiet. In contrast, the 2164 design is near-silent.
