Jadis jp80 vs Conrad Johnson art 2 or opinion on best pre amp

I want to hear opinion which preamp is best,my experience so far I think jadis jp 80 and Conrad Johnson art 2 or wavelength 

I have always wanted to demo a CJ ART3 pre-amp.

I have spent time w/ the CJ Act 2 Series 2 and it is very fine.

Happy Listening!

Jadis Jp80 more tube like CJ better stage,imaging and bass also quiteer better service as well.Good luck!
Any other better preamps
