That looks awesome! What do they cost?

That's not a compression horn, there is no throat or aperture. Just because something is patented, doesn't mean it works.

Thanks for posting that.

Here is the schematic:

Here is the inside:

I didn't design the circuit, but I did the chassis and point wiring. IT's Steven Deckert's ZEN Triode 2W x2 stereo amp. Sounds fantastic through my Cornwalls, and plenty LOUD. Right Click "Open image in new window" to see it all.

The Cornwall III speaker grills now use neodymium magnets at six locations on the grill frame, with steel inserts in the from of the box. This works very well. This link shows some options: http://www.kjmagnetics.com/products.asp?cat=10

Because the drivers have that power handling capacity. The power rating is not related to listening level.

My 10 Watt Jolida push-pull tube amp drives my Cornwalls to volume levels that will drive people out of the room. I am currently building a 2-Watt SET amp, which will be plenty of power, I am sure.

I believe the agreement states you are buying a limited personal, non-transferrable license. You took the bargain. More importantly' all you are getting is a low grade MP3 compressed file.

Great looking room, and challenging for loudspeaker placement. It looks like a pair of Cornwalls on the stepped-out walls between the three windows would work pretty well.

The Cornwalls are 102 dB speakers, the Heresys are 94-96 dB, so there is a big difference in volume at the same power. Also, I assume that amp merely parallels the speakers to the output, so the amp is driving 8 ohms with either pair alone and 4 ohms when A+B are driven. Last point, I believe the Heresy IIs were all 4 ohm speakers (at least mine are).

I found a picture, the blue things inside the power box in this picture are surely the power supply filter caps. http://www.canuckaudiomart.com/image.php?image=1474828&is_user=0

The filter caps will be BFC's (big fat capacitors ;-), and will be leaded, near the power transformer and rectifying diodes (or maybe that amp uses rectifier tubes). They will have high voltage ratings like 200V, 300V, maybe higher. They will also have high capacitance values like 22uF, 33uF, maybe higher. Usually there are 2-4 of them on the plus and minus rails. It is also possible you will see physical damage to them. Of course, they are polarized electrolytics with a "+" terminal marking. They should be easy to find.
