Esoteric CO3 preamp vs Mark Levinson 326s


Thinking of upgrading to the 326s or the co3. Do not need phone stage. Will be used with a Mark Levinson 335 amp and B&W Matrix's 800 speakers. Speaker wire and interconnects will be Transparent Ref MM2 and the same interconnects xlr Balanced. I listen to Classical to Rock to Folk to Jazz. Would like to hear pros and cons of both preamps.
Thank you for your time.

Just a note regarding the Esoteric C-03, they have released the upgraded model C-03x. You may find some original C-03 preamps still available but they should be priced accordingly.
You don't say why you are upgrading. Do you have a specific issue with your system now that you need to fix? Or, are you happy with your current setup and just want an overall improvement? Also, what preamp are you currently using?
Hello Zd542
I am slowing moving away from home theater to 2 channel. Would like to know the pros and cons of the Esoteric preamp and of the Levinson preamp?
