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??

The P3's are great at any volume, I have the larger Harbeth 30.2's and play them softly most of the time, they still sound wonderful at low volume. Go back and have the dealer play music you like at a lower volume. One thing I did was buy an integrated (Luxman) with tone/loudness controls (bi-passable) to help at low volumes. Yes, an actual blasphemy for many audiophiles. But at low volumes it really helps me enjoy the music, and that's what counts.
@ labelman
I have owned many small and larger speakers and I always go back to the P3. I have not listened to the newer XD. Ask your dealer if he will let you take a pair for an in home audition. You can find many on line reviews on the Harbeths. This guy likes them as much as I do!
