Swampwalker: After rebuilding my Father's speakers, my Brother and i listened to them. To be quite frank, they sounded like hell. My Brother was worried that we had done something wrong i.e. that the speakers were worse than when we started. I told him that even though we used all of the existing parts ( caps, resistors, coils, drivers, etc...) that had thousands upon thousands of hours on them, all of the solder and new cabling inside of them was new. As a point of reference, the sound was phenomenally bright, harsh and fatiguing.
When I told my Brother that the speakers and system needed to "play in", he laughed at me. After he left, i put the Ayre disc on repeat and it ran for 3 days through the system. I had the volume up pretty good, as high as i could run it without damaging the system. Needless to say, nobody was home while doing this.
When my Brother came back and heard the system three days later, he thought that i had changed every piece of cabling in the entire system. It was so much warmer, smoother and focused that the differences in sonics were undeniable. When i told him the only thing that i had done was to play that disc repeatedly, he went and looked at all of the cabling for himself. Not only was he convinced, he now uses this specific disc for break-in purposes himself.
Having said that, anyone attempting to use this disc should use extreme caution. Not only can it damage your system if caution is not used, it is possible that other items outside of the system could sustain damage due to extreme low frequency energy and the resultant vibrations. This disc WILL shake your room and possibly the entire structure depending on the construction of the building and the volume level. As such, one should listen to the entire disc at low volumes to see what each track entails prior to adjusting volume beyond that point.
Yes, this disc works. Especially track 7 played on repeat at good volume. Those with vented speakers beware. Sean
