Esoteric C03 preamp or Mark Levinson 326S preamp- ANY and ALL FEEDBACK / HELP PLEASE


Esoteric C03 preamp or Mark Levinson 326S preamp 

ANY FEEDBACK - THOUGHTS - IDEAS would be so appreciated.

I am in the middle of total system re-fit and have made many changes - I am sure too many but I am quite happy now and now have my preamp choice down to these 2-preamps.

Can you guys provide any feedback about either of these. I like to hear from you guys. I read all the reviews on both and those are all well and good but I always get the real ho-down low-down from you guys - good or bad.

                                                ** Back Ground info**

** Room is 
14 x 24 w/Cathedral Ceilings - 16 Foot a peak

** Music likes:
Assorted Music no metal or loud hard rock anymore really - not much Large Scale classical either but everything else.

** Likes / Priority: 
Transparency - Delicate - Linear - High resolution - microscope but not sterile not etched or lifeless - I know there is a fine Line here but I'm looking to walk the line as close as I can - real see through into the music - transparent to the source because I love my DAC - extended and to remove as many layers without being clinical - image and sound stage lover - tight bass - hate flab - like speed and transparency but needs to be musical. 

** Perspetive
Just had a BAT VK32SE brand new tubes / certified pre-owned, mint same as new preamp. Wrong match. Just looking to go total other way. Not what I am looking for.

** More Perspective - I have been running my Bricasti Direct M1SE to my Pass Labs X350.5 amps and really starting to love it. I want to expand on this sound a bit. Little more depth, width of stage, bass, dynamics but don't want to add veils or give up a lot in transparency - I know I will give up some vs direct in doing so. That is why I am looking for the very best SS preamp I can get in my range and have come up with these two choices and wanted to know your thoughts.

A good customer bought the Esoteric C03 and after listening to it in his system thought it actually broken b/c it lacked air, dynamics and just had no life. He brought it to my place and it collapsed the soundstage and he was right it took the life out of the music. Based on this he sent it back to Esoteric to verify everything was fine with the unit, got it back and no change in sound. So based on using this pre-amp in 2 different systems I would not recommend it although it does get excellent reviews.
I too use the Bricasti M1SE and also an Atmasphere MP1 but full disclosure I'm a dealer for each but have found no better YMMV. Have never heard the ML 326S.

(Dealer disclaimer)
sksos1 thanks for the information. 

I have heard from more than a few people the C03 can be a great preamp but many think it is sort or bright, etched and can be flat if there is nothing else in the chain to round out the lower mid-bass ie, tubes, warm cables,etc. 

Glad to hear from a fellow Bricasti owner. The only thing I have had left over from my old system that I have no desire to change at all.

There may be better out there but each change I have made in my system it has advanced with this being my source. It seems to have no ceiling or at least at the level I am operating at. I am sure there are many that have much better systems than me and for them maybe they expect more but I have been extremely happy with my Bricasti from day 1.

So I a deciding on a new preamp on Monday and basically everyone on here has told me they think the Mark Levinson 326S is the unanimous choice.

Anyone else. I have until tomorrow when I am going to decide so would love any/all feedback between now and then. No matter how little or whatever info is really appreciated.



There are two newer versions of the C03, being C03x and later C03xs.
Sound stages & Sound stages Ultra reviewed these units as well as the C02, which is a higher up model.
from what I remember, one of the reviewers in replying to letters stated that these units have a "lovely romantic sound", but that they don't have that oomph for the bottom end.

since your Amp is a Pass, have you considered the Pass preamps like P20 or P10? They may have better synergies together...
if you're in Europe then there were a few of the Passes for sale on different boards just recently, and if in Asia then one or two units out of Hong kong on the bay...

I looked at the 326 for my Levinson amp and all the reviews were all good, however there wasn't that much enthusiasm about it which I suspect was due to it's relatively high cost at the time it first came out ($10k circa 2006)...so I guess this to be a very good unit especially if you can get it at a good price...
still I'd suggest, if at all possible, to listen to anyone of these before purchase to make sure they match the rest of your system, and think twice about the synergies of the Pass preamps...
Good luck
Thanks for the info and feedback. I’m in US - Boston. They’re is a couple XP10 out there and it’s quite a bit less money but Ive heard over and over it’s a decent Preamp but the Mark Levinson 326s, Esoteric C03 and Ayre K-1xe are all in another class.

I did think about the Pass but it’s about to be replaced and really would like to get the best pre i can and set it and forget it but yeah thought of the Pass for sure. The Esoteric is the oldest one. There is one in Canada but it’s over double the price of these. I’m in the second hard market $4k price range for the best SS pre i can get.

I did Just have a Dealer offer to take my Pass amp and BAT pre and the cash I was going to put toward the Levinson and he would give me Vitus Audio RI-100.

i wasn’t looking at or considering Vitus but everywhere I read everyone says Vitus is the very best match for my Magico S5 Speakers. Hmmmm

I would think my Pass Labs X350.5 and a Mark Levinson 326s would be better than the Vitus RI-100 but i guess should at least consider but doubt I’d do it. 

What do you guys think?
