Who is using passive preamps and why?

Seldom has there been any discussions on passive preamps in the forums and although my experience with them has been limited I have found them so far to be very enjoyable and refreshingly different. They seem to fall into their own category, somewhere between solid state and tube. Finding a preamp that is satisfing has been difficult. Some active solid state preamps can be very good but they seem to inject grain to some degree in the upper registers and some tube preamps are not too far behind. So far I think they should at least be matched up with an amp that has sufficient gain which is often overlooked. Which passives are you using and with what amp? Why do you like them?

Just bought an Goldpoint SA1 25kohm volume control. Proabably a more direct assessment than talk. Phd, see what you started:)

Pubul57, you have done an excellent job of explaining the technical aspects of this subject and I as well as others have learned a great deal as a result. Given that, you now have my permission to go home and get some sleep! But I expect you to report back first thing in the morning, I don't pay time & half. In the mean time if we have any problems I will call on Herman to police this thread, as he may still may be angry.

no, no, no, no, no, no, no, no, no, no, no, no, no, no, no,

I'm not angry.

Passionate? ok

Tired of seeing people declare absolutes in a world with so many variables? ok

After so many years on these forums tired of seeing the same things debated over and over and over? ok

But I'm not angry. Amused perhaps after seeing the same preposterous statements repeated over and over (like passives are wimpy) but perhaps frustrated would be a better choice as it frustrates me that there are people like Phd who come here to learn and they get responses about passives that are so far off base that they are worthless at best and at worst scare the uninitiated away from a topology that could be the answer to their quest.

Herman, I am happy to hear that you share the same frustrations as I do but you never know when to take me seriously. I know you are not angry but still I respect you and have alot of love. Thankyou for being here to share your thoughts.

Herman, My previous statement "If you want to select components, speakers and wire around a volume control it's ok with me. I prefer the sound of an active preamp because it sounds like music".

And this is why there is a variety of equipment for sale.

I knew someone would come up with an amplifier manufacturer that makes a passive preamp. That's why I threw it out there and I'm not surprised it's Modjeski.

I did infact buy an amplifier with a passive gain control and it was the best amplifier I ever heard and still is. When Kron developed the Vaic tube he wasn't getting the results he expected, so, he went to a little amplifier builder in Italy called Mastersound to build and amp around the Vaic tube. The amplifier was named after the founder of that company, Caesar, and uses the 32V output tube. This amplifier makes all other amplifiers sound ordinary.

I also own a Manley Stingray which uses a similar design, but these amplifiers were designed this way.
