In Reply to: RE: Ayre IBE "demagnatizing" burn in cd? posted by Tweaker456 on August 14, 2016 at 11:47:36
Inspired by this thread, and curious if my now-vague memory of the IBE disc was accurate or not, I picked one up from Music Direct; it arrived yesterday. I put it through my main rig, which hadn't been "cleansed" in well over a month. (The last time I did it, I used the IsoTek disc, which I've employed for years now.)
Results were impressive. I only used Track 7 (and only played it once, at fairly low volume). I noticed more air, stage width, and clarity (the last especially true on cymbals), and the low end seemed to become more defined as well. And I didn't have to strain to hear it. I can't offer a particularly valid comparison of how it stacks up to the IsoTek CD, because I haven't run the Iso in more than a month, but my GUT impression is that Track 7 of the Ayre IBE disc, AS A REFRESHER, makes at least as much sonic difference as the Iso's demag track, and more difference than I remember it making from past experience.
I took somewhat detailed notes. I'll run the IsoTek through the rig in 2-3 weeks and see how my impressions differ from my thoughts on the Ayre. Not scientific by any stretch, I know, but it's the best I can manage. :)

and check out what shakes and rattles in my room and system... I found and repaired two seam cracks in my older main speakers.
Also found several fancy decorative jars with lids that needed dampening to keep the lids from rattling at low subwoofer levels...
I agree, Track #7 is great!
Even though I had owned the Ayre disc in the past, I had kinda forgotten about how low that frequency sweep goes. I thankfully don't hear a lot of vibrating in my room at low frequencies, but your post reminded me that the sweep is good for tracking down objects in the room that do audibly vibrate.

I'm considering getting the Isotek as I have the Ayre and Nordost set up discs.
Please report back
I'll definitely report back, Hawk, but having used the IsoTek for a few years now, I can say that it's a great disc to have in one's toolbox. Whether it's better or worse than the Ayre, I guess I'll find out with more experimentation, but regardless of which one comes out on top (if there even is a clear-cut winner), I'm now glad I have both.
BTW, how is the Nordost disc? I've never tried that one.

Class D amps don't seem the like the Ayre disc. I have no idea why.
Also, running both back to back seems to make things worse-again, I have no idea why.

That's bizarre that Class D amps don't like the Ayre CD. What exactly becomes worse in the Class D presentation after treatment? A friend of mine has a Merrill amp that he just bought, and he's looking for a burn-in disc, I told him about the Ayre, but I'm wondering now if I should loan him my Isotek instead.
Yeah, I generally don't run different break-in discs back to back. If I decide to change, I let a fair amount of time accumulate on the system before I experiment with the new disc.

I've tried it with 2 ICE Power amps and a (pair) of PASCAL based amps.
After using the disc, they tended to sound "off" for lack of a better term, a little muddled/confused. They definitely preferred the Isotek.

and the Red Dragon Class D monos I used to run.
Everything seems to just open up a bit and get in tune.
