Speakers that sing

Good recommendations above. For vocals and acoustic jazz I would look for a pair of Spendor SP-100s (if you have the space for them). New, with stands, they will still run toward the low end of your budget.

I've heard SP-100s paired with a Bryston amp and the combo was great.

Silverline Sonata MK.lll. I just got them as an upgrade to the Sonata MK.ll and they are stunning. they now incorporate the Dnya Esotech tweeter, midrange and wolfer drivers. They are more transparent and smoother in the upper range and deeper and richer in the bottom while retaining their glorious midrange. I don't know of a speaker that is better from top to bottom in their price range including the one's mentioned above.

SEAS Thor. This is an incredibly clean MTM design that is an excellent deal. Check out www.madisound.com under the kit section. One evening with a screwdriver and you will have a speaker that is easily outperforms many speakers in the $5-10,000 per pair range. Don't be afraid to spend less than you had planned!

Used Wilson Watt Puppy 5.1 or 6 or 7 can be bought for under $10K. They are neutral, efficient, dynamic and "accurate", quite a bit better than the B&W Nautilus 803, 802, or 801.

The Piega P10s are going for the low side of your range, or less. I highly recommend that you add these to your list for auditioning. They are tremendous speakers, and an amazing value at $5K or less.
