My first post here on Head-Fi so be understanding.
some background: I've never considered myself an audiophile but I do appreciate music and it's proper reproduction. I can remember the joy of discovering stereo output on my old 8 bit gameboy when I plugged in headphones into it. Also when audio cd's were just starting to go mainstream I found out about the SPARS code and would specifically buy albums just to hear its quality. I've always been fascinated with headphones, of all sorts.
I guess my audiophile'ness is really limited to my poor budget and really, I just enjoy music as it is fed to me and I'm really not anal about it.
Well, why am I posting here? in this thread? because I have proudly modded my 4g.
I picked up a used and broken one for $15 from some online forum. I purchased it for the sole purpose of using it my car as a music box. (USAspec ipod adapter for my honda accord) It was a dead drive deal so I obtained a converter and crammed in a CF card and tossed it into my car, never giving it another thought.
fast forward a year or so.
I picked up a Sansa Clip, generally known for its clean output. Soon after I began hearing things in my music (or the absence of

) and was quite entertained. One day on the road, I wanted to hear something on my Clip that wasn't on my ipod so I plugged it into the line in of the USAspec module. HOLY SMOKES, it sounded good. I started to go through all my music in my car with the ipod and then with the clip. BIG difference. I was RUINED. I began to hate my 4g Ipod and it's muddled, filtered and violated output but I just couldn't give up the convenience of steering wheel controls. I played with the equalizer and it just sounded worse.
Fast forward a few months up to last night. I found this thread. This wonderful wonderful thread....discovered at 10pm on February 25th 2009. By 12:30am, my ipod was Modded.

Now keep in mind this is for my CAR so don't criticize too much, but I cannibalized an old discarded modem for it's caps

They were 22uf 50v badboyz. I don't even think they had a brand. I also ripped two strands of wire from an 80 pin IDE ATA cable that worked AWESOME for it's flexibility and tininess.
The only hitch I had was I dePadded one of the contacts coming out of the DAC but I made do by scratching the resin off the PCB over the trace just to get an adequate purchase on the contact. *Whew* it actually worked. For a moment there the white flag was coming out of the bag to be unfurled.
With fingers crossed I plugged it into my car and tested it out. (don't have a LOD for headphones) It worked! Sure enough, the output is DRASTICALLY better and noticeably more dynamic, even with my untrained ear. It's hard to describe but the only word I can come up with is CLARITY. Even adjustments to the equalizer were effective in improving the sound, before it was like attempting to patch up a burnt dinner.....impossible. (I'm using all stock components -- actually the 2003+ accords have relatively decent equipment)
Well, that's all I have to share. I just wanted to pipe in and give everyone on here a big thank you for your knowledge and experience of this whole project.
Now I'll go crawl back into my hiding cave.
cheers.
