Good speakers under 10K.

Used Sonus Faber Cremona

Based on your room size, I would also consider the Vandy 5s. But you should budget for a dealer to pay you a visit and set them up. If that isn't a possibility, consider a pair of Quattros, new, at about $8K. That price should include dealer setup.

For something completely different, consider a pair of Ohm Walsh 3000s. New, they are $4K pr. Their sonics are very much what you are looking for, IMHO. They come with a 120 day in home trial, so you only lose the shipping if you return them. I've had a pair of 2000s for 2.5 years, and I can't think of a new speaker under 10K I'd rather own. You can read my review in the speaker review section. Used, might be a different story. But you need to audition before you buy, and a home audition is the best way. FWIW, your idea of buying the amp after you choose your speakers is the right way to go about it.

where are you located? Thinking of selling mine vandersteen 5 with an ayre integrated amp, (crossover in the amp) or you can use it as a pre amp.

Aqua,
Have you decided on a speaker? I have a speaker in mind that might be what your looking for.

I would also advise you to read the thread "Micro Talls Who's heard them"? and visit the Ohm website, and if you're interested, call John Strohbeen and talk to him personally about what may be the best choice for you Joe
