Seeking Suggestions on Preamp Upgrade (CJ, Aesthetix, EAR)

Can't believe no one mentioned Ayre.  (my personal fav)

I'd recommend you investigate the Primaluna Dialogue Premium which I now own. I've owned CJ ET-2SE, Aesthetix Calypso, Allnic L1500, AR LS17SE, and First Sound Presence Deluxe MKII in the past 4 years. If it wasn't for the lack of remote, the First Sound is the most impressive I've yet heard and I would have lived with it long term. The Pirma lacks the sheer dynamics of the First Sound, but is otherwise equally enjoyable. Good luck in your search.

+1 for the Primaluna Dialogue Premium pre recommendation. Performance far-far beyond its price range!!! A tube rollers delight... 

Hi David,
I have been using the Aesthetix Calypso with Genelex Gold Lion tubes that I got from Kevin Deal of Upscale Audio. A great upgrade from the original stock tubes. The preamp has worked flawlessly from the time I purchased it. Its a neutral sounding  pre , highly musical and bullet proof.  Its a match made in heaven with my Jadis. I would highly recommend the Aesthetix Calypso ( with the tube upgrade, or you can also get NOS Telefunken, albeit , a little more expensive tubes  & get an even better sound   sound )

Excellent exchange of info here guys.  Happy Listening!
