Copying audio CD with dd/cdrecord produces unplayable CD

[Yuri]

I am trying to copy an audio CD.

First I've ran:
dd if=/dev/acd0tN of=track-N.cdr bs=2352
for every track. This gets raw track files.

Secondly I run:
cdrecord -v -dao -audio $* dev=2,0,0 speed=4
This is supposed to recreate the original CD.

But when I try to play it I can hear only noise.

What I am doing wrong?
How to troubleshoot this problem?

burncd doesn't work on my system: it breaks with my PIONEER DVD-RW 
DVR-112D/1.21.
