Recommendations for speakers that sound great at lower volume levels.


I have a pair of Harbeth SHL5 Plus and they sound wonderful when I crank them up. But at moderate to low volume levels they sound disappointingly flat and unengaging - instruments are less palpable, bass has less bloom, and soundstage has less air and dimensionality. I drive my speakers with a tube integrated - a Line Magnetic 845 rated at 26 watts of power. My Harbeths are rated at 86db. Would a higher sensitivity speaker be helpful? Or how about a good quality small shoebox sized pair of speakers coupled with a subwoofer? Or not. What speakers are going to deliver music you can feel at low volume levels? What say all you wisened audiophiles?

Another consideration is what digital cable are you using?

In the last 2 weeks I swapped out my optical cable for coax. If you're price conscious, check out Audio Advisor who has a sale on Pangea: I started with a 1.0m, then a 1.5m (which to my ears sounded better), and now using their 1.5m XL, which allows me to play at lower volumes as the music is more intimate, BUT, I can also play louder $150/1.5m XL and free shipping!

Don't forget to at least conisder wide band high sensitivity speakers, Great at low vol, 
Of the loudspeakers I have experimented with specifically listening to at low volume the loudspeaker I have found to be the most enjoyable at low volume is the Wilson Audio Chronosonic XVX (and I am a life-long planar speaker person).
Different amplifiers in any range by the same maker have different responses at lower levels. I use Bryston and each new product is slighty better at lower volumes, so it is incremental and not speaker dependent
