The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G! - Page 34

Pins 1 and 2 are identical, so you can use either or both. I know I said to use pin 1 because it's "farther" from the audio pins, but looking at the dock connector, both are just beside the other, so it makes even less difference which one you choose.

KoKo:

I agree with you about the iMod reviews. I think people are exaggerating the improvement in sound quality, though it may very well be there. At the very least, it's an interesting concept, and I'm just glad I could do it for so cheap. I wonder if anyone will be going to the National meet and doing any comparos. Oh, what a controversy that would be.

My impression is that, the iMod has very very slightly deeper midrange and bass than mine, however it was quite an unfair comparison considering he probably has his music on lossless and mine on 192 kbps. Also, cause he was rushing off, I wasn't really in a right state of mind to do a calm comparison, I might be wrong because the difference I heard was so so so small. And i only clocked about 130 hours of burn in, when supposedly supposed to go for 200... I will definitely do a comparison again. But overall, my verdict is that iMod's reviews are mostly over-exaggerated.

He listened to my mod as well, his feedback is that the bass although not as powerful as the one from headphone out, it is more controlled and the clarity is better(which is expected because the headphone out is known not to have exceptional clarity). However, comparing hp out to dock line out, I would say, like most people do that the hp out on 4G iPod is already good as compared to those new gens, so the rather inaudible difference that I am hearing in terms of SQ might be explained by that probably.

KoKo, I was thinking...what size caps did you use again? If it was a smaller value then his iMods 47uF, then that may have been why you are hearing less bass in comparison. It may be that, or like you said it could be the way your files are encoded.

thx for the URL...yes, i'm pretty sure now that my dock had the right pins...

But yes, you are on the right track. What I tend to do is put the wires on the side instead of directly on top of the small pins. This usually helps out quite a bit.
it's help alot than using directly from the big gauge wire to pins...

i use the 22uF, so it's gonna be less bass to than RWA iMod ?

Same as RWA, 47uf. RWA uses Cryogenic wires though, which again, shouldn't make much of a difference... zzz

i think it might be the file encoding and burn in time that's making the difference I hear.

If you leave capacitor leads exposed like in CAvanessa's dock, do you need to worry about signal interference?
post #502 of 2999
True, that could be it...then again you should probably give it a better listen!

You do, but at the length she left it, I still wouldn't worry about it. [What with all the vampires she's using, she has bigger things to worry about, like static buildup and odd looks on the bus.]

And KoKoKrunch, congrats on being the 500th [post]. [And congrats to powertoold for having the 500th reply.] Let's keep a good thing going.

haha.. this thread is going on forever!

has anyone tried to mod the nano fatties?

I think they would look at VVS more than they would look at me Althugh his music would sound so good that he would be too phased out to notice.

My "rig" is for home use only. The PK3/Nano are for portable use.

BTW how should I Prevent signal distortion in my cap? Shorten the leads? Elecctrical tape the leads?

There probably isn't any noticeable interference from that set up.. electrical tape wouldn't make a difference though, not to an electromagnetic field. the best thing you could do is orient the wires so they're parallel as little as possible, like one orientated along a y axis, another along an x axis.. though honestly, these voltages at these frequencies with that much space isn't too much of a concern.. I'd waste my time on other stuff. (I'm assuming the recommendation to remove the unused pins in the dock are to minimize higher frequency interference from the data pins, etc.. distortion is another issue, and I wouldn't worry too much about it now either.. (it would be on the line of using inductors in parallel to your outputs to balance phase distortion, for instance..)..

Does anyone else have this problem?

After reading some V-cap dock impressions, I have decided to sell the remainder of my BG caps and supplies to get some Soniccaps (hey, I'm a poor graduate student. I can't afford the V-caps). I will enclose the caps in a plastic enclosure from Radioshack or a larger mint-tin I have. No fancy stuff here

i think i had the same freeze problem as you guys...but there's a chance to fix this problem and i already downgrade the software to version 1.0 myself (do on my Mac)...i'll report if i found any problem like on version 1.3.1...

Goodluck !

note:
here's a screenshot for my ipod that detected on iTunes after downgrading the software...

Reading around quickly, the recommendation seems to be to just reset the iPod. Toggle the hold, reset it by holding the menu and select buttons. They also say restoring the iPod can help. Does anyone else have this recurring problem? Mine seems to have gone away. Actually it wasn't freezing on me, it just kept pausing. Apple has "The 5 Rs for iPods": Reset, retry, restart, reinstall, restore. Follow the link for more information.

Haha, 500th post. Joneeboi still thinking of making a webbie for this?

but this battery supply with one year warrent from the date of purchase
