difference between an active and a passive preamp?

hi,
I have a nad c272 amp and am looking for a good preamp to go with it, but I am on a very tight budget. I see lots of preamps that are acive and some passive - I have no idea of the difference? I have quad 22L speakers and listen to cd only. Any help understanding these differences would be great. I just want simple 2 channel preamp, with as tube like sound as possible. Please help, and many thanks,
jason

I am bumping an old thread here!

I am leaning towards going with a passive preamp. Although, I am not into numbers too much because as long as you like the sound, who cares but in this case, I think it is important to check some numbers.

Is passive preamp suitable for my setup?

DAC: 
  • Output Level: 3.0V RMS Max. (Analog).

  • Outputs: Stereo (RCA) 300 Ohms.
AMP:

Input Sensitivity (RMS) - @3Ω, 500W,1KHz 1.36V

Input Impedance - 33K ohms

Thanks! No, mine is a stock unit.

I am leaning towards the Tortuga Audio but have not made my mind yet.
