Bookshelf speakers for small room


I have a small room and listen rather closely.  I'm using a Uniti Atom and some older Martin Logan 4s and looking to upgrade the whole system with a great turntable, tube amp and a different DAC.  A local dealer demo'd me on the Harbeth P3 XD's and the vocals came through with crystal clarity- loved the sound!  But he played it loud and I'm playing at very low volumes (kids, wife, small house).  

What are some good bookshelf options for a small room and streamed music (and vinyl) played at lower volumes?   A good tube amp/DAC to match??

That Luxman is a cool integrated, but obviously a touch pricey as it will take up basically half of your budget.

In addition to the Harbeths, Spendor Classic 3/1 would be fun with that size room and the Luxman.

That will leave you about $3500 for the turntable/cart and dac.

Rega P6 with the Ania cart would get in around $2000, so about $1500 for the dac then.
I have Focals, Quads even sweeter.
It sounds like you want high efficiency near field speakers of which I have no experience.
Those Odyssey bookshelf speakers have great reviews. 
 Martin Logan bookshelf’s are nice!

 BIC America bookshelf’s are nice, good bass for a small footprint. 
 Energy RC-10 bookshelf, no longer made, but sound great, and are pretty easy to find a new pair for a descent price.
