Passive Preamp - What makes it work?

What does a passive amp do that's better than one that's not? Does it have benefits? I'm not educated enough to know what a passive amp is used for?

Would not a regular pre-amp always be better than a passive?

Theresa, there are (as always) several views on this subject.

Some say that passive preamps are superior and follow the "less is better" rule. A passive preamp can only cut signal. It cannot increase signal if needed, nor can it actively impedance match between multiple components.

Others believe active preamps are better because they can more effectively manage all types of signals. Active preamp's have many more parts, require power and process the signals fed into it, often adding their own personality (for better or worse).

Some Audiogon members go the no preamp route. Instead they choose a CD player with a volume control and drive direct into the amp.

All three answers are correct provided you have the right combination of equipment.

Theresa,
I just copied the Q&A section from Placette Audio's website in an ad I posted for a passive (placetteaudio.com). It addresses your question and you may find it interesting. I think the Q&A section was listed on the bottom of the list on the left hand side of their home page.

Types of passives should at least be mentioned. There's a transformer type I know zilch about, and three resistive types: (1) potentiometers, (2) series stepped attenuators, and (3) ladder stepped attenuators. Almost everyone would agree that (3) is much superior to (2): I've built both with identical resistors and comparable rotary switches, and the difference is easily heard. Some very costly pots may be competitive with (3), but most are clearly not, IMHO. Whether passive or active is better is an unending dispute, but everyone would agree that it depends heavily on the system, in several ways, and that passives are trickier to deal with. In my opinion, they're well worth it, but others will disagree. It's a much-discussed topic in this Forum: maybe you could look up those discussions.

I tried the Creek between an Odyssey Stratos and MSB Nelson dac, shortest possible IC's ( 1.5ft) and hated it. The soundstage became very flat, entirely 2d. Bass and trebble extension was outstanding, imaging was just ok, vocals where hollow and lost presence, overall just didn't sound "right," was only a stereophile class "C" component for a reason. For the cash it can't be beat, but there are many better preamps out there for not much more on the used market. Still, you must try it for yourself in your own system to see what you like. I would suggest trying the Adcom 750 pre as a good alternative that has an active and passive section, and can be had for around $600-700 used.
