The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G! - Page 115

Has no one tried the iPhone/iPod Touch?

If someone can confirm whether it works or not, I would be very appreciative. The iPod is the weak link in my setup, but I can't live without my Touch.

Anyone?

Apple 30 GB iPod with Video Playback Black (5th Generation)
iPod Nano Headset Music Player
Apple iPod classic 160 GB Black (6th Generation) OLD MODEL

The weak link in sound quality?

It's probably possible to mod those, but I haven't heard of anyone doing it.

Yeah, it is. I would like to get as close to a at-home DAC as is possible in terms of SQ.

well I dont know if you'll get much closer than the 5.5G with a decent large capped dock. the iphone/touch output stage is better, but IMO the line-out is about on par, with just a smidge more soundstage on the iphone 3G line-out when compared to the VCAP dock its not a fair fight. not sure how much improvement you would get from the mod on those 2.

if you want to go further I would suggest going the external dac route with a box like EFN with iriver. i've started on a similar solution with the gamma1 in a larger enclosure with battery power; also thinking of upgrading the caps because I will have room. its gonna take me a while to finish the rig tyhough as there is a bit of R&D to go on first as well as the rest of my life that is competing for my audio bliss time of late

thought i'd add another pic; do with it as you see fit Jon. It was an absolute PITA peeling the old clickwheel assembly off and putting it on the clear button. next time i'll just buy a new clickwheel assembly

love these clear panels; makes it SOOOOO much easier for me to explain what is going on with my ipod this one is 120gb too, designed for transportable

also a couple of VCAP docks this one with USB charge/sync, 4.7uf OIMP VCAPs and 0.47uf teflon in tin foil Bypass caps (TFTF) and those cables I posted a while ago.


this one is 'just' OIMP in 4.7uf and OT man the kramer mod SPC re-cabled Koss just scale soooo well with a proper source. this is a swiss army knife dock with mini I/O as well as LOD in and RCA out; was a bit of a squeeze, but all went according to plan.



I really need to get myself some nicer rubber bands and before anyone says anything; yes i'm aware that the RCA to mini is extremely tight in this pic; I have remedied this with a new cable, this one is for another combo

It could be different in the mini 1G, so you'd have to double check the continuity to be completely sure.
Sorry to resurrect an old post, but I just got a mini 2G and will diymod it soon. I don't really understand the pic above: do the wire go from C53/C54 to C59/C60? Leaving L7 and L8 alone or removing them like explained here? And the result is I'll have a diymodded line out on the connector?

BTW I added this thread to my search engine, as the diymod's success makes navigating through it really hard, despite the excellent work of the OP. The search engine is in my sig.

Haha! Thats the first time one of my posts has been linked

All I can say is I did as that post says and it still works great after nearly 6 months - the standard line out pins are modded.

Don't worry about bumping threads as big as this, there's far too much info in here to be lost on page 7

I am looking to do this to my 1st gen Ipod mini and I had a question of what to remove and where to mount the new wires. By looking at the photo it appears I remove c53 and c54 and attach the wires there, but do I just connect them at the dock connector on an open pin? Perhaps pin 14 and 17. Also what pin on the dock will I want to use as a ground when I build my new dock connector? Thanks!

You can get rid of the L7/L8 inductors or you can leave them. When you solder to that part of the C69/C70, the inductors don't affect the circuit. And thanks for adding us to your search engine.

nic6paul:

When you remove the capacitors and send the wires to the pads, you don't need to connect anything to the dock because those particular capacitor pads already lead to the dock, pins 3 and 4. If you want though, you can grab the signal straight from the DAC and send it to the open pins if you're really fixed on the idea.

Let's hope mine works too. I just did the mod, but after 10 days the Qables connectors are not here yet. Grrrrrrrrrrrrr.

Well, thanks to you for a very useful thread.

I left the inductors in place, this is what I did



If you see anything out of place, please tell me. The cables are 28awg from a Mogami mini dual mic cable.

I think you should remove those caps, my full mod is in post 991

I finished my mod on my ipod 1st gen mini. Soldering those little wires is something else. I did test the line out even though I didnt have my caps yet and it seems to all be working just fine.

Couple of questions:

In this diagram done by bmwpowere36m3 he cuts the traces from DZP1 that are going to C69 and C70. I was wondering is this necessary as I haven't seen this done on other mini diymods. My assumption is if I left those traces be all I would have to add to my dock is the caps on the line out R and L traces to the jack and not have to add resistors like he did on his dock?

And second question:
Any suggestion on what value caps to get for use with a 41hz T amp?

That's great to hear. Welcome to the club.

The series resistors on the line out are meant to protect the DAC from the effects of shorting the output. A resistance to ground doesn't achieve the same thing. As far as I know, no one here really knows what the DZP is there for (it was suggested at headwize that it was a zener diode), but it doesn't seem to hurt anything when you remove it. The datasheets for the Wolfsons say the the resistors are there to "protect the line outputs from damage when used improperly." I assume that means the effects of shorting the output when unplugging the mini TRS plugs. Maybe it would be a good idea for this thread to venture into the hifi resistor area of audio.

What caps were you talking about?

I was referring to the DC blocking caps on the lineout of the ipod. I didn't know if there was a certain value that would be better suited for a home audio system. My buddy who helps me out with all my audio questions is out of town.

I have read decent reviews on these caps Obbligato Film Oil Caps | Diy HiFi Supply

I was just unsure what value to buy.

By the way thanks for the great thread, the photos are a huge help!
