Best system for jazz?

My musical tastes have shifted and now I find I listen mostly to jazz with some classical, bluegrass and space music thrown in. I'm just curious what kind of systems provide the most enjoyment for you jazz fans?
Horns and single fullrange based driver speakers, with low power tubes or flat out low power, high quality class A amplifiers.

Jazz, reproduced with technology existant in the time of its heyday is the most accurate and exciting sound you will ever get.

I really enjoy my Audio Note system on jazz. It has a beautiful open and natural tone that consistantly reminds me of live music, especially the way high notes 'cut' through the other instruments but maintain musical identity. Percussion instruments of all kinds are well represented, much like a live performance, but not at the expense of midrange which is harmonically rich and very neutral at the same time. The bass is not fast and tight, it just sounds like real bass. These are terrific 2 way speakers that are easy to drive.

BTW, I have AN-E speakers but have not updated my system info...
This jazz flunkie uses Supratek Sauvignon/ Atma-sphere M60s into Silverline Sonatas IIIs and for my taste this is just divine.
Space, pace, transparency and focus in spades and just plain natural music. For me that is what makes a system cook with jazz.
