Upgrade entire system, speakers first


I want to upgrade everything but thought I would start with speakers. Room is about 10 x 12 ft. Current system is Arcam alpha 8 integrated, Arcam CD and PSB bookshelf speakers on stands. Listen to mostly jazz and chamber music but would like to be able to listen to orchestral pieces as well. Budget for new system will be around $10K, thinking SS integrated, CD and speakers, new, not used. I would like to start with speakers now, maybe $4K and upgrade components 6 to 12 months later (cash flow!). Any suggestions for speakers appropriate to my small room would be appreciated (with comments on components to match in the future).

My first suggestion, buy preowned here on audiogon from proven sellers and save huge money. I've been doing this for 8-10 years now and wish someone would have advised me similarly. The markup on audio equipment is crazy and most audio nuts take great care of thier components. So, find what you like then look it up here. Make sure it has original packing for safety save a few grand. If you can spend $10K new on equip. why not spend either $5K used for the same equipment OR $10K for a $30K system??? BTW, look at Merlin speakers very carefully, I couldn't be happier!
Thanks for the responses. I do like the idea of easy to drive speakers but am reluctant to try any DIY projects.I have done some reading on the web about acoustics, treatments etc. I have tried to audition several systems however I find that many systems even retailing around $5K or so don't sound to me that much "better" than what I have now, eg bookshelves from Focal (Chorus?),B&W (805), Neat (Petite). I'm not certain I can describe what I want other than a more "full bodied" and natural sound. Suggestions regarding specific equipment to audition would be most helpful. Used is a bit difficult as it involves International shipping which is why I wanted to stay with new equipment.
Maybe the Green Mountain Callisto would be good, the sound amazing, just not sure if you will be far enough away from them (1storder crossover) but others will chime in.
Also look at DK Design for Integrated, tube pre and SS amp built into one, even has a Phono stage at a great price, and it sounds really nice.
Artch, where are you located?

What larger - presumably unaffordable - speakers have you heard that you do like?

Have you considered just moving up the PSB line, or are you looking for something significantly different?
