iPod Classic... DAC and output stage info from Vinnie of RWA

[trose49]

Seems like a simple lineout to lineout would give us a starting point no?

Question really is a 6GB lineout better or worse than a 5.5G lineout stock and then is a 6gb Line out vs a 5.5 imod (no V-dock) better or worse ?

Is there any word of the relative sound quality of the new Nano?

It seems they're entirely different output stages. The capacitors that are replaced in the iMod process and the problems they bring appear to just not exist in the design of the Classic. The Classic may still sound worse for other reasons (DAC, etc) but that's really just speculation at this point.

Yes, it's that kind of impressions that are currently lacking. I have a Classic myself but no access to any 5.5G iModded or otherwise.

IC so we are on the same page relatively, I read a few more of Vins posts elsewhere and get the impression he is pretty happy with the 6G sound.

Thats good for us and bad for Redwine I would say.

How about the iTOUCH I would guess if APPLE now makes or re-brands a DAC it's in all the new toys? Even though the storage is so low I would wait for the next higher Flash Memory but would love to know whats in the NANO and the iTOUCH?

Vinnie,

Got an idea: Kudos to the first person (As well as a TON of sales) who can add an optical line out to the iPod 6G. I say strip the headphone jack out of the iPod and put a mini optical output in its place. I bet you could do it! Might take some serious effort, but anything worthwhile does.

I'm pretty unhappy with my stock 5G sound. It's amazing how bad it distorts even with lossless files, LOD, silver cable, etc. When the signal gets close to peaking, it compresses the soundstage and distorts. It's really quite awful. If the 6G doesn't do that, I'm in for one. Although I'd much prefer a DAP with an optical or USB line out, as I mentioned above.

Pretty much. It's good Apple is now making a product with fewer flaws requiring third party fixes but changes like this often hit the enterprising few like Vinnie who fix things Apple should have in the first place.

Yes, we need more autopsy pics!
I'd guess you are right, I think all new iPods will have Apple branded DACs. Many companies do this so they can switch suppliers if a part maker starts ramping up prices on a popular product. It costs more to design a chip to begin with but generic chip foundries are cheaper to work with in the long run.

So now the question is, do I run and get one of the $450 80 Gb iModded iPods from Ken w/ one of his docs for a total of around $600. Or do I just get a 6 Gen 160 Gb iPod Classic for $350 and use my ALO Six Shooter?

Since I could sell my ALO Six Shooter for about $65 the difference would only be about $200.

Vinnie already commented on that idea. There's already a company doing that and look what they charge.

I'm a little disappoint that G6 has no room for improving sq,and it's still behind 5.5G+Black gate dock. But Vinnie is so sincere that I hope that Apple
would have been screwed up agian, so Vinnie would make it right.
