I know I havn't been on this forum in a long time, but I noticed how many of you are jumping to buy the new ipods and I thought that you might want to read this first:
http://homepage.mac.com/marc.heijlig...surements.html
*NOTE* Read the page above with a grain of salt, the information has been contested with more reliable equipment by our forum members. Also, there is no physical proof that Cirrus has replaced Wolfson, although the evidence seems to be mounting in economic reports.
Be sure to have a look at the graphs in the lower half of the post.
Here's the conclusion: "From these measurements it is obvious that the Cirrus audio IC is worse that the Wolfson IC:
- Treble has an uplift of 0.1dB.
- The Codec has a non-linear group delay.
- The phase faults are caused by non-linear effects.
The audible impact is significant, and a firmware correction (most Codecs contain programmable parts) is definitely required to bring back the iPod sound quality to normal levels."

More worrying are the graphs below:

Both links are from DAPreview.net; they found that the increase in battery life is actually proportional to the additional boot/loading times. In other words, the new ipod has actually been crippled.
and not improved. Video capability has, as you know, also been crippled through the HO.
You'll all thank me someday.
