I absolutely love these loudspeakers.  They deliver so much more than I have ever experienced from a system, and I have three or four others.  Including the Vandersteen 5As.  And yes, that is the Constellation Audio Inspiration Integrated amp.  There is amazing synergy.  I have two other integrated amps, one ss, one tubed, and this combo is it.  Also in the system is the Luxman D-10X disc player.  I love love love the beauty of the sound these three make together.  But, the Perlisten are the star of this setup.  I am amazed each day by what they do.  Just pure beauty.
