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??

Thanks all for responding.  Looking forward to your suggestions.  Room is 11 x 12.  Budget is $15K.  I love acoustic guitar, jazz and deep vocals (e.g. Nick Cave) mostly.  I listen at lower levels.  Oh, and I have Sennheiser HD800s w/ Sennheiser HDVD headphone amp but am not happy with the fatiguing highs so will swap those for perhaps the Focal Clears.  @Deadhead- I'm looking at the Luxman L380.  I also love vinyl and am finding the TTs are much pricier than I had hoped.  Looking at the Luxman L-171.  
The Harbeths sound great at low volumes. If you liked them, I wouldn’t look too much further. In general, you might focus on those British monitors - Harbeth P3, Spendor A1, Falcon LS3/5A, etc. They were made for the type of set up you have, and they do voices extremely well.

As an aside, I have owned both the Harbeth P3esr and the P3 Anniversary Model (same/similar to the XD), and I preferred the standard P3esr - a little warmer and more relaxing. Some might argue that the XD is more accurate, but I felt that the standard P3esr really connected me to the music better.

Have fun with your search!

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.
