Guys if you want to test the mod completely free of caps, you need to make sure the following ....
 
1. Your amp is able to handle the dc offset, regardless of how your amp is designed with or without dc blocking caps
2. No dc offset from amp's output to iem's or headphones.
 
By the way, I again measured the dc offsets from apple's lod and the numbers were like 1.5 volts. My measured dc offset from the amp to my iem's is zero.To produce the cleanest sound possible, I also disconnected the headphone jack from the board (wrap the cable end with some electrical tape). If connected,  the board would be still feeding the audio to the headphone jack and it would still draw power from the battery. As much as I want to remove more unnecessary components from the board, unfortunately I have no idea about what/how to remove.
 
So this is the cleanest audio path we can get with this mod, also the most power efficient for the battery. Now I don't know if this is placebo or not, but I am now hearing the most neutral, transparent and cleanest sound ever, after I tested it with a few tracks (symphonies and orchestral work) which I consider the most muddy prone due to the nature of the music composed.

Sorry man to hear about this but you are a lucky guy for having a girl friend like her.

Maybe having more exercises or some therapy will help you?

It's not that bad it just shakes enough to where it's difficult to do pencil like activities

Yeah I'm lucky for sure, and she's slowly developing audiophile tendencies lol

Looking into the matter further, my suspicions were confirmed. It is well-documented that the iPod 4G, as well as the 5G and mini, uses the PortalPlayer System on Chip (SoC) PP5020. Thanks to Generations - wikiPodLinux , the PP5020's datasheet confirms that SPDIF/I2S is being employed in these iPods. Check CommsDesign - Find out what's really inside the iPod also for some good information. At any rate, this confirms that digital out is possible for the iPod, you just need to get creative in figuring out how to get it.

 
Did anyone manage to impliment spdif in the end - sounds good solution to me ??

Why are we looking to get digital out? I thought the Wolfson was the superstar of the portable DAC world?

Try boot it to Apple's OF and write it from disk mode. That will help.

I didn't use the exclusive disk mode but the Apple OF. I got close to 1.8m but nothing better.
 
Im not sure if its better to remove the SD and use it in the macbook for music transfer….

Hi guys.

Do you have a link to the 128gb sd cards you are using?

Also can anyone recommend caps you can get in the UK?

Thanks

That's very slow. With my 256GB CF card, I get around 12MB/s in disk mode or 8MB/s from rockbox.

Yes you can use the thicker one. (Free space depend on the cap. I also use the sd conversion)

Thanks for your help.
 
Just wondering what amps people recommend to go with this?
 
LOD to Fiio E18?
 
Would that be suitable?
 
Thanks

I highly recommend the UHA-6S.MK2 which is very neutral and transparent. Also this amp can handle your diymod with or without caps even tho the amp has no dc coupling caps in the audio path.
 
I only us the amp for iem's, no cans.
