best 5-20K speakers for high-end tube amp?


I have a Jadis JPS2 tube preamp and Jadis 845SE tube amp combination, and want to get a pair of speakers which really show off their sound. I currently have a pair of B&W804s, and I figure that seriously upgrading my speakers will give me a significant improvement in sound (these speakers are in a much lower budget range, and not ideal for tube amps I believe). What speakers would you recommend to really get the best out of my equipment? I heard the magic with my Jadis amp in the store with a pair of Wilson Puppys 5.1 in the store. My home system has decent sound, but not at all 'magical'. My currently listening environment is about 17 x 25 feet (9 foot ceiling), and I generally listen to jazz, pop, world (everything from indian classical to spanish flamenco to andean flute music, etc...), and vocal music of all kinds.

I figure the budget will be between US$5K and 20K somewhere, and I will try to buy used, but this will be difficult since I live in China.

Hi been away.

Sold my Avantgarde Duos and bought a pair of Hyperion 938, my budget was $15000 but got these as an interim prurchase for $4000. Never regretted selling the Avantgardes once. Suddenly I had bass I had TONAL COLOURS with great inner detail NOT JUST WARMTH. A soundstage was suddenly once again apparent. It was quite plainly very involving musically. I owned the Avantgardes for two years so I did like them. Had valve amps, solid state amps had the Jadis JA 80's etc. No way does it compare to a good cone design.

Exiting and can be electrifying when set up right, but not a great all rounder and not the most natural sounding by a long margin in my opinion.

If you want it to be electrifying dyanmic and exciting you have to give up a little of the tonal riches which to me make music special. You use a Jadis and yes you get warmth but you lose transparency and a little of the electrifying presence. Their bass is one of the worse I have come across from any speaker and I have owned which include Audio Physic Avantis, Harbeths, Quads, etc.

Just look at the two two intermnet reviewers Steve roachlin and Sjragen, I believe they have both given up their duos for paper cones.
No_slouch,
If you like the tube sound, try the Dan a Digital speaker (www./danadigital.com). I'm lucky enough to live in Australia to hear it out ( Aussie made speaker), but not rich enough to have one :(. Don't know if it's available in China, but absolutely you MUST listen to them. Hearing is believing. I never heard any kind of sound that comes as live concert from speakers. Don't laugh but I would have one when I win the lottery.
