Sam Tellig in Stereophile was all jazzed up about a line of "passive pre-amps" he received for review How does a passive pre-amp work?? Is it powered by wall AC?? What are some of the pros and cons of its operation within an audio system??
Atmasphere, I am not sure I understand the "5. = control the effect of the ic" if it isn't already included in the 4. ie the low output impedance sees the ic's impedance+amps input imp.
1. source selection 2. voltage gain 3. attenuation 4. buffering (impedance matching) 5. tone control (older preamps,typically)
Now, it is up to user to define his needs,since "the simple is the better" (or Okahm's razor) principle works in audio as well! I ended removing the 2.,4.,and 5.
