Are passive preamps better?


Does a passive preamp with transformers so that its impedence can be matched with an amplifier have the potential to provide better sonics than a line preamp? I have a Simaudio Celeste preamp and a Harman Kardon Citation 7.1 amplifier. Lynne

Passive worked for me but I carefully selected a CDP and amps to match. Half volume will shake the house. First impression was incredible tranparency but that something was missing. After going back and forth between SS. tubes and passive several times, all the passive was missing in this combo was noise, distortion and embellishment.

Talk Thunder 3.1b - 4.2V XLR/ <100 ohms
DIY TVC (Bent/S&B) 0 gain
dual, bridged Plinius SA100 - over 38 dB gain
Genesis 350's - 96 dB
combined with the Genesis servo - that's a lot of wattage
A really good active preamp will actually be more transparent than a passive preamp for all of the reasons mentioned by Albert.

Using a passive preamp places demands on source components that they are often not ready to meet. Even with the rare capable source and good impedance match, a passive unit is a pure impediment or drag on the source and the signal with no upside.

I will go a step further and say that in the best systems the preamp is often more of a determining factor than the power amp in the overall sound quality of the system.
When I asked the question, the passive seemed more logical to me. Now the active seems more logical. I'm sure I will experiment when I have the opportunity. I think the 7.1 is probably 22k (just got in from delivering a calf and am too lazy to look it up). H/k usually is although this one is Madrigal. Thanks for the interesting disscussion. Will research Placette and Manley and Joule for sure. Don't stop. It's very interesting. Lynne
I have Wyetech Topaz 211 tube mono amps and had the Placette pre in my system for several months and although I appreciate what it does , it was a sheer pleasure to replace it with a good active ( Audion 2-box linestage ).
The music is now alive with lots of impact .
Hello, I have been using a passive preamp for the last eight years or so and had tried them prior to that. I was also trying SS and tube preamps till the passive "won" the contest for me. No loss of dynamics or sonics but improved clarity and resolution with decreased noise and colorations.

I have no need for switching as I only use a TT, though that is possible with a passive, I use "naked" attenuators (no switching). Why add unnecessary gain, colorations, expense, complication and noise if you dont need the gain?

Now it is active 12 to passive 7. Not as terribly lopsided as one would think.
