Passive preamp vs. powered


I have a custom made passive pre-amp that I purchased from A-gon some months back for about $150. It only has a volume control and 2 inputs - perfect for my needs.

It sounds excellent...

My question is... what would be the advantage of a much more expensive powered pre-amp? Sure, maybe I would have powered switches and more inputs, but I don't need any. Are there some differences in sound quality that I'm not hearing?

This is typical of the passive vs. active discussions you will find. A real mix of experiences and preferences. One thing I will say, is that every passive I tried offered alot of bang for the buck, they are very good in many ways and hard to beat for the money assuming proper impedance matches, a tube amp is almost always a better choice due to its high input impedance. Ralph knows 10,000x more about this than I do, and I have to believe his position is proabably sound, and it may be that an amp with a built-in passive volume control would provide the best option. I can only say that as much as I wanted to love them, because of their simplicity and price, over time, I prefered my CAT, Joule, or Atma-sphere tubed preamps. The only answer to this, is for you to try it and draw your own conclusions because you never going to get a defintive, conclusive answer - it really is a matter of going with your ears and deciding for yourself. On a budget, I think choosing a passive is a no brainer, and for some, even when money is no object.
Very interesting thread. My experience with highly regarded passive preamps vs great tubed active has always been the same.

The passive ones seem to sound more transparent, fast and detailed. After longer listening and comparisons one resounding thing became clear to me time and time again.

The perceived greater detail etc... of the passsive was actually the absence of body, texture and weight.

Threadbare sound can often seem more transparent at first, but in the end the passives lacked the meat of a great tube preamp.

It's a relative thing to be sure.Some passives have meat, body and texture, however not as much as a great tubed active preamp.

In the end the passives I've tried over the years simply lacked the meaty,earthy and substantial weight/authority of an active.

But, this is key. I don't like a thin, fast and detailed sound. I'll give up detail for natural musicality.

So my opinion does not mean actives sound better for all - just to me and what I like my music to sound like.
>All passive models I have listened to have been a disappointment ultimately<

Jallen I would be willing to bet you have never heard a passive device using autoformers or transformers. Maybe Grannyring hasn't either. In an appropriate system one of these types of linestages can whip the pants off far more expensive active preamps. At least that has been my experience.

Amandarae,

"I always examine the equipments of the owners reporting the claim and make my conclusion as to what they have or had and build my impression from there."

Here are some active preamps I have owned (in no particular order):

AI Modulus 3A
CJ Premier 17LS
Lamm LL2
GNSC modded Audio Research SP9 II
Art Audio VPS DM
Gill Audio Alana
Cary SLP-98
Dehavilland Ultraverve II

Do you think any of those would qualify as "decent to a very good design active preamp "?
