The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G! - Page 206

Can I do the capless mod directly to the lod of an ipod 5.5 with a fiio l9 lod, a topping nx1 amp and a pair of shure se215? (I know that it's better if I upgrade my setup, but right now I don't have a job and to be honest I neither have any kind of soldering experience).

If your amp has a capacitor to block DC, then go for it, else the amplified DC will do some damage to your earphone.

Don't know. I just asked in the amp thread... however, what's the difference in your mod between the se and the balanced one?

No difference. Differences are balanced or single ended termination.

 

If you mean the differences between iphd mod and diymod, it would be the cabling for grounding/-ve path. For diymod, the bypass and cabling are done on the signal path only while iphd mod is for both +ve and -ve path. However for iphd mod, the player will not be able to play on stock or original rockbox firmware and require custom rockbox firmware.

I asked in the topping thread and they told me this:
"They're 1uF polypropylene with 0.1uF PP bypass caps that will block DC but, because the input impedance is high, they won't cause too much low-frequency roll-off."
"The NX1 is is 0.5dB down at 20Hz, which will be inaudible. Yes, you could remove the output caps on the iPod since the NX1's input caps perform the same function. But it looks very fiddly."

I think I'll go for a direct-out diymod capless. Anyway, if the music volume is too low can I add the cap in the lod right? Any raccomandation for the wire or other thing?

I got a NOS iPod.

Do you think I should MOD it?
Or should I buy other new version player instead?

I don't know DIYmod.
If you think I should MOD it, what is the best option I could have now?

Thanks so much

Hi,

 

here [http://redwineaudio.com/mods/imod] they offer an Ipod mod. Since they mod it via a “custom dock connector”, I assume they are offering the classic diyMod (with external caps).

 

Now, is really what is claimed there, that is

 

IMod improvements over stock iPod:

 

Increased resolution of fine detail
Better bass control and definition
A richer, more seductive midrange
Superior treble extension and sweetness
A larger more 3-dimensional soundstage

 

Product Features:

 

Exclusively for 4th, 5th and 5.5 generation iPods
Leverages built-in Wolfson DAC (same DAC used in many pricey CD players)
Bypasses iPod’s analog stage that was not designed for audiophile playback


 

Specifications:

 

iMod line out voltage: ~1.0 Vrms
Output impedance: < 1k
Battery life: Same as stock iPod

 

5th and 5.5 generation iPod:

 

Headphone jack remains unchanged, and can be used for headphones
iPod’s internal docking connector now outputs an audiophile-grade signal
5G / 5/5G iMods require ALO Audio iMod dock cable
Apple-supplied USB cables still support charging and music transfer"

 

achievable via the "portable" dynMod (with internal caps – such as Black Gate NX Hi-Q 6.3V 22uF or 47uF) illustrated at this link [http://www.tarkan.info/20090113/tutorials/modding-audiophile-meets-ipod-diymod]?

 

If yes, I am really interesting to mod my Ipod with internal caps, but I am not able to do it in my own. At this end, if there is anyone available to help me somehow, I will really appreciate it.

 

Thanks a lot.

Hey all,

 

First post here after reading headfi for almost 4 years!

 

Thing is I found an almost 10-year old IPod 5G and decided to mod it.

 

I have some questions, please bear with me as I have ZERO experience in electrical engineering (I took really long to read the entire thread, oh well but some of the jargon is too difficult for me to understand)

 

What is the size of the capacitor that I should look for if I am using an IPod 5G 30GB

 

Does the voltage of the capacitor matter? (I've seen people use 6.7V for the BG caps)

 

What is general consensus on the type of capacitor, there are people using 4.7uf, 47uf, 22uf, is there a recommended one that I should use?

 

I am leaning towards a more bassy signature, does different caps affect the SQ?

 

 

Also, anyone with experience about the direct method without caps that Dminor posted?

 

Does it mean I just have to connect from the DAC left/right to the LOD pins without going to the onboard dock connectors?

 

Do I have to "desolder the coupling  capacitors near the DAC, the inductors near the dock, and the capacitors that comes right after the dock inductor." as mentioned in the website in order to reroute?

 

http://www.tarkan.info/20090113/tutorials/modding-audiophile-meets-ipod-diymod/2

 

Sorry for the long list of questions, lots of the guides on the web have been removed and leaving some with expired photos :( I really hope some1 would make a new guide soon!

 

Thank you all for the valuable 200+ pages thread!

Direct out is cleanest (I did it before dminor).

You do not need to unsolder anything with direct out, only cut the out pins connection to board.

Adding caps will change sound slightly.

Though you will need amp with caps on input.

post #3085 of 3088

Thank you for the kind reply!

Does that mean if I added caps within in the ipod, its okay if i do not have any input caps on my amp? (im looking at diy partially for fun and also costs reasons, not really motivated to get a new amp :/ )

Hello,

 

I'm also interested into mod my two iPod's (5.5 with 80GB and 5th Video with 30 GB). The last one will get a 64GB-SDXC-card mod with stuff from Tarkan. Also on his side there is a description of a diyMOD of an iPod (5.5 gen.) with internal caps. I understood that this is not a direct out mod. With this description you don't need a special custom dock connector. Am I right?

Unfortunatelly most of the links here in this thread are deat or the images posted are gone.

 

The user "paulus germanus" posted a link with images. Is this a direct-out mod? I just want to be clear.

For a direct-out mod I need a custom dock connector. Where can I find one or a how-do to make one?

 

Thanks in advance

Huberer

I want to do a capless mod to the default Line out (Which would be L2 and L2 if I'm not mistaken). Then use a Fiio Line out to the UHA-6S MK2.

Am I correct in assuming that I only need to remove the caps next to the DAC (As seen here: http://i8.photobucket.com/albums/a13/jERiCOh/IMG_5689.jpg) and for the 2 line out pins (As seen here: http://i8.photobucket.com/albums/a13/jERiCOh/IMG_5683.jpg) and then solder the wires from the DAC outputs to L2 and L3?

 

 

On top of that I want to install an mSata SSD using Tarkan's adapter. The ipod should run rockbox. I've read a few things and it seems that I need to use beyondwind's patched rockbox version to get mSata SSD support in rockbox. Has anyone got a decent explanation of how to do a 1TB SSD Rockbox Ipod?

I'm not an expert, but the L2 and L3 are the default audio line outs, so a normal Fiio L9 should theoretically work. I'm looking into doing the exact same thing but capless.
