If you have a CD Player, you need to do this periodically...

I put in the Chesky demo disc ran it for a while, Class A system.  Did the track 7.   Then back to the demo disc.  My noise floor is -93dB and speakers 19 woofers and 2 inch horns, both Faital Pro.  Perhaps a bit better in the midrange but details were the same.

I think that running a frequency sweep through a system is good in that it gives parts a full range of exercise.  Just like a break in it loosens things up.

I just want to thank you for posting about the Ayre IBE CD. I used it after receiving it a few days ago.  It is effective and improved clarity and fine resolution in my audio system.  Subtle in scale however definitely noticeable.  Quite an admirable feat for 20.00 dollars. I appreciate you bringing this product to my (And others) attention. 

Not every tweak I've tried has been beneficial.  This one is worthwhile. Whatever it's doing to the system components,  the end result is a positive one.

I used the Ayre CD with a Pro-Ject RS2 transport connected to  my Yamamoto YDA DAC.

Should I or shouldn’t I wear a tin foil hat while doing this? Obsurd...been in this hobby for over years and bought one of the very first cd player when it came out, never have I had to do any of this. This is right up there with cable elevators and slinky springs, good gosh....
