Topic: Zapping your CD's

is a review of a device a friend of mine is considering purchasing.  Personally, I'd like him to, just so I can try it on a few of my old CD's, without spending money!

So, any thoughts?  More expensive snake oil for gullible audiophiles?

"Ditto for their ongoing experiments with producing copies from commercial CDs that far transcend the originals "

sure sounds like snake oil to me.


think about it. if all commercial cds were somehow inferior, would eac be able to rapidly rip identical bit-for-bit copies quickly (at speeds much higher than 1x your cd player reads at) almost every time from new clean discs?

That article was almost comical! thanks for the laugh.

I read the article twice.  It actually makes sense to me. 

I have no problem with what they're proposing that this device does; however, I'll be the first to say that I'm no audiophile so I can't say whether it's something that could be worth it or not.

Regards your statement Jerryfreak, you aren't contemplating how they are saying that the device works.  Basically, if I can translate how I understood it, if a CD or DVD is sorta like a punch card, it's almost like the device fixes the 'hanging chad' by zapping it with a calibrated bright light.  The light isn't so bright as to burn through virgin foil, but it's bright enough to burn through 'hanging chads'.  In essense, it seems to me that the concept is that it burns additional holes onto a CD and DVD that didn't get there in the first place because of maybe imperfect CD/DVD manufacturing processes.  By completing the burning of the occasional 'hanging chad', there is in essence more data (more holes in the foil) and better sound, better video, etc. 

As they say however, you can overdo it because the light is so bright.  If you keep zapping it with the bright light, at some point you start destroying the virgin foil and thus the quality of the music data starts to also get corrupted...and the output sound of the music starts to suffer.

So, regarding your statement about EAC, it's not really relevant because EAC obviously just reads whatever holes/data the laser in your disc drive can see.  If it can't see data because the 'hanging chad' is still present, then it's not gonna read it.

ok, so when EAC reads the EXACT data for just about any disc you rip, and compares it with an accuraterip of someone else on the other side of the world, and they are bit-for-bit identical, why is there even an arguement that the 25+ year old technology of cd pressing is flawed? i have yet to see a new disc that doesnt rip fine.
