Best preamp for my system.


I am looking to upgrade my preamp, and am looking for advice from experienced audio people. I am currently running an Emm Labs CD player into a Levinson 380S and then the Levinson 33H's and on to the Genesis 4 tower speakers. All signals running through Gabriel Gold Rapture IC's. What I like is a real lush sound, vocals being most important with respect to accuracy. Some preamps that I am considering are the ARC reference and Lamm Reference.......but am open to suggestions if a serious upgrade from my 380S can be had for less than those two expensive units.

Just to keep anyone up to speed who is reading or following this thread................I sold the Nagra and bought the Joule Electra LA300 (Marianne)preamp. Don't get the wrong idea, I loved the Nagra......didn't like it's looks, loved it's "sound". Now with the Marianne, I feel my preamp search is over. I find it to be like a woman that is somewhat attractive at first, and the more you get to know her the more beautiful she gets........rare!! As much as I liked the sound of the Nagra, it never came close to having that affect on me, no piece of audio equipment has!
Glad to hear you're pleased with the Joule LA300 (Marianne). I've had the Joule LA-150 Mk2 for a couple years and have never thought about changing preamps until your post. Simon emailed me the other day saying that the SE upgrade is definitely worth pursuing, which adds some of the trickle down changes that were put into the Marianne version. I will have to go that route considering the price of a new Marianne.
I'm about 460 hours into break-in on an Esoteric C-03 preamp. This unit is truly something special. I now know first hand why it won 2 Blue Moon awards from 2 different reviewers on 6moons!
I've heard a little about the Esoteric preamp Mark, but will have to check out those reviews!

I have moved on from the Joule and bought both an Atmasphere MP1 and MBL6010D to compare, thinking I would keep the one which worked best in my system, which I did. The Atma has moved on and I am using the MBL now!
Let us know how it turns out...it's always great to hear about your latest audio adventures!
