While the whole article is a piece of comic fiction, complete with so
many factual misrepresentations about CD replay that it's not worth
even trying to list them, two things did strike me as interesting:
1. Thay claim that the laser angle is adjusted during re-reads. I have
no idea whether this

It's also my understanding that software such as EAC provides statistics
on each rip in terms of how many reads were necessary to get a 100%

you get in terms of read accuracy?

The MP uses a Plextor PX-716AL drive with a feature called
IntelligentTilt that controls the laser in three dimensions, to ensure
high quality writing and reading if the disc surface has imperfections.

On the flash wearing out issue, its not really that bad. There are
different types of flash, some can go to over 100,000 writes.
The number of writes is to a specific address, not to the chip as a
whole, thus most flash disks have an internal algorithm that spreads
the writes around so the same

From a cursory skimming of the article, it looks like EAC in what is
sure to be a very expensive box.
It is the correct idea as we all know but it's reinventing the wheel
for those who can't or won't use a PC.

It's called the Slim Devices Squeezebox. Heard of it?

I've had many discussions with proponents of the Nova Physics player
regarding some of NP's claims...it's my personal opinion that while
they make some interesting points, EAC-in-a-box and compact flash
memory are cheap, and not nearly costly enough to justify the price of
that player.

And there is more tosh. I found this just glancing at the text:
But just like the perfect sound forever business, RS-ECC, according
to Mark, falls short of perfection. And, he goes on, because RS-ECC is
not perfect, it is at the top of the list of reasons why the quality of

It is all just marketing speak to lure in non-technical audiophiles.
Snake oil.

With such a major technological innovation, I'm disappointed that they
did not figure out a way to restore all that analog data lost between
the digital samples. :-P
