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.

You may want to consider Coincident's Total Victory for your application. They are an easy load for tubes. And they would be able to fill a listenting room your size with as little as 15 watts.
Silverline Audio Sonata MK3 great sounding speakers retail for $7,200 a pair and can be drvien with 10 watts SET amp.
Thanks for the responses so far. My amps are 20 watts per monoblock. My living room is actually about 17 x 35 feet, but through sofa placements I only use about half the room, or 17 x 20 feet or so.

Teajay, my preamp/amp combination retails for about 35K (luckily i got used for much less than half), would the Magnepans be a good match just from a budgetary point of view? (10:1 value ratio of amplification to speakers)
No slouch,if your Jadis mono-blocks could drive the 3.6s,I know that tube amps often sound more powerful than their formal rated power specs,than I do not think their is a budgetary mismatch at all. The 3.6s compete with much more expensive speakers in my opinion. The next step up in Magnpans is the 20.1s which are phenomenal,and I would argue are still a bargain even at $11000.00. However, the 3.6s give a great taste of what the 20.1s offer at a much lower price.My only concern would be if your very fine mono-blocks have enough power/current to drive them. Maggies with the right tube gear is a match made in heaven. Hope this helps.
excellent gear!!! (i am also a huge jadis fan) i suggest looking into horns made by avantgarde and acapella. they are super transparent and musical. if horns are not for you, i have also read great things about coincident (Nutella's suggestion). good luck!
