I agree, rockbox is amazing firmware. The cue sheet integration is great, and the hardware eq opened up by rockbox works well too. The number of settings to work with are mind boggling.Video quality is nice on the 5.5g but small. Switching between the two firmware is easy.
The potential sound quality of the device is great. I say that because the internal amp is so-so and the output impedance of the device is fairly high. There are other devices that will sound better with in-ear headphones out of their headphone jack.

Worst EQ in the world.

it's a matter of individual's opinion. I too prefer Wolfson over Cirrus because of its dark and warm tone and I'm no fanboy either.
 
The Wolfson vs Cirrus thread is a long gone past and I can't believe there are still people who can't stand the others' opinions, coming out crying like a baby.

i know it has been 2 years since the rockbox ipod classic 7g arguement.  but i just wanted to point out (with a thread from 2011 so that it would have been relevant at the time) that the ipod classic (aka 6 6.5 and 7g) are/were rockboxed at the time, they merely weren't part of the rockbox installer.

(see thread started in 2011 here)

(thread from 2012 where a guy talks about installing rockbox on his 7th gen ipod)
http://www.head-fi.org/t/630401/ipod-classic-160gb-7th-gen

as you can see just under the title on the first post it specifically mentions the 7th gen ipod.  so no, he wasn't lying you were merely misinformed.  

P.S. i hate it when people call others a liar so i just wanted to clear this up.

Thanks for reading my mini rant!
