- I'm ordering one from Digikey today. I've tried to
- make my own active filters from the section in
- Horowitz&Hill, but they never sound better than
- passive filters. Apparently you need a dozen or
- so poles, precise R and C values, etc. The ones
- in the Digikey catalog look simple: 4 pins, Vc,
- ground, in, out. $10 or so, a variety of values,
- even some adjustable ones I think.
