Thank You for sharing your experience. Those Atmasphere Class D replaced the Audion and First Watt, says something about what these can do. Hope that you get to own the Avantgarde loudspeakers some day and fulfill your dream!
And you have paired the Saadhanas with the Atmasphere Class-D!! Would love to hear more about how this combination sounds. What was the previous amplifier that these Class D replaced?
Hope you are having a ton of fun with this system making music for you.
