Check out Green Mountain Audio speakers. The Callistos sound excellent at low volumes (specifically, they sound great at the lowest volume possible with an Ayre AX-7e integrated). I would expect the Eos and Eos HD to perform even better.
Good speakers at low volume?
It's a known fact that a lot of speakers "come alive" when they reach at least moderate volume levels. However, since I live in an apartment, I'm looking for a good speakers where I won't lose all the details while playing at low volumes. In that respect Audio Physic speakers are great, full of detail, unfortunately they lack dynamics for me when I happen to listen to rhythm driven music. I'm thinking 4-8K price range (Dynaudio, Dali...). Any suggestions are appreciated.
