Need Advice on Preamp - Audio Note M3 vs Jadis JPL

I need some help on selection of preamp. I am using Wadia 301 CD connecting direct to Jadis DA8. It was great until I have a chance to borrow a Jadis JPL preamp and put in the system. Everythings become more detail with a bigger sound stage! As I do not have a chance to try out the Audio Note M3, I wonder if there is any experience out there that could give some comparison between M3 and JPL. Many thanks.
I'm afraid I don't have any comparative experience with these units; however, I do currently own an M5. My reaction when I began using it was how clean and neutral the unit was. There is much more air around the instrumentation. I don't know whether this Jadis is considered Warm (as some
other Jadis equip is), but I know the AudioNote is extremely neutral.

Should you decide on an AN let me know, I might be interested in selling my M5 as there is a potential I might have access to something I have been lusting over for some time.
Ekarg, regarding your M5, whether it is better to use balance output than RCA? I know that M3 does not have balance input, is it the same with M5?
