but do I believe once people do the comparions between the iMod and the line out of the 6G, you'll hear where the line out of the 6G falls short. Its a little thinner sounding and not quite as warm.
Hi Vinnie,
I can confirm this observation as well after many times listening and comparing the 5G and 6G. The 6G has an audible uplift in the treble region, but is also less "harmonic", also w.r.t. its line output.
Enclosed are some measurement pictures (Classic in red, 5G in blue), first frequency response of the headphone output, then the line output, and finally the step responses.
The measurements clearly show why the iPod Classic sounds less warm.

ugh, thats not very pretty... I think my little brother would love it though. I really wonder how the 1st gen Shuffle compares now.
Interesting topic and results but why can I not hear any noticeable different with my shure E500PTH / SE530PTH when swapping inputs between 5g and classic? (been listening 10 years to music, jazz, metal, rock, pop, classical and my mp3 quality is –v2 or –v1 lame normally).
I do believe the results and what people are saying but I think it has to do a lot with perception (placebo) and what size headphones you are driving.
However from the measurements it does seem the DAC is worse and a firmware update could fix some issues.

Welcome, HiFivoice -- and THANKS for your link to the FR measurements... NICE WORK!
The more I listen to the line-out of the 6G (in comparo to the 5.5G iMod) the more I hear a thinner sound and less bass weights and fullness. It is also "flatter" sounding (less 3D), which might very well be the result of the timing issues that you measured.
The thinner sound mostly likely has something to do with the peaking in the top-end that you measured, and maybe other things.
I am not measuring the bass rolloff that I see in your plots... I'm curious about this.
Thanks again!
Vinnie

so 6G is reli degraded from 5.5/5G!!?? rather than bein cleaner n better SQ-wise as stated before?
i was just about to buy it tomorrow....
hope apple would offer an update to fix these soon....

Marc, thanks sincerely for doing that. They are certainly interesting and insightful, so your time and skill is appreciated!
Though the measurements fans will call this 'conclusive proof' while the feelings people will say they are completely invalid!
Huh?! This confuses me. Does the G6 now sound worse than its predecessor?
Vinnie, you stated before that G6 sound better, at line-out as well as headphone out... not right anymore? ^^
ok i tested my classic vs my asus xonar soundcard out with my shure E500PTH / SE530PTH headphones and some high quality wav sound ripped from cd just for this
all i can say is that the only difference I can hear is that the classic does indeed have higher highs (mhhh) or something.
bass sounds superb on both (as in amazing drums etc.) and overall sound quality is not much worse or better then my soundcard appart from the higher highs it seems...
ipod sounds amazing

Note that the scale of the curve is 1dB. So the fall-off looks steeper than usual curves. I also guess the PowerMac G5 input line is not completely flat.
Hifivoice, you could use REW (a java application used to equalize a subwoofer fro a specific room with a parametric equalizer) in order to check the soundcard response from line out to line in, just in order to know what degree of variation is present from it.
This is accomplished with a simple loopback between input and output. Of course it won't be perfect, since you would be checking teh full i/o instead of just the line in, but it can give you a good idea.

God leaned close as mud as man sat up, looked around, and spoke. Man blinked. "What is the purpose of all this?" he asked politely.
"Everything must have a purpose?" asked God.
"Certainly," said man.
"Then I leave it to you to think of one for all this." said God.
And He went away.
