LOL Those are not pipes. They are the tops of the amplifier Vacuum tubes, or valves as they are known to our British and Canadian friends. These are tube amplifiers, not transistor. Any additional cooling would be provided by whisper fans. Tube amplifiers generally are exposed to allow the better dissipation of heat. While I and many others go to great lengths to set up a system to "play the room" this setup seems way over the top to me, but then I've never heard it, and in the end the sound is all that counts. The Apogee duetta signature IIs. speakers are a thin panel only a few inches deep with a ribbon mid range and tweeter and bipolar quasi ribbon planar bass panel. They need a lot of air and space around them to do their magic and I fear that may be somewhat impeded by the presence of so much gear and equipment in front of, and behind the plane of the speakers. The various bricks, baskets and sound material on the floor, ceiling and walls is intended for diffraction and absorption to, among other things, break up lower frequency standing waves.. Effectively it maximizes the speakers ability to deliver the pure bass the speakers are capable of by eliminating the effect of the room. In the end a properly set up and amplified pair of these speakers will generate the illusion of a huge sound stage that extends well beyond the side and front walls, and both the walls and speakers will disappear. The instruments will be placed in this sound stage as they would be in a live venue. It is not only a startling illusion, but with great recordings it can be a an extremely stirring emotional experience. Now, after that digression, back to photography.

He has some cooling pipes to help cool off the room from the heat the Ref-600s generate. Everything else you said is spot on....
and it's freaking crazy how it sounds. So amazing and yes the room is completely silent.... you cannot hear the walls and such.
I especially like the boxes of Dynamat and also the bricks on the bookcases, nice bookends!
