iPod Modification Ideas

[soap]

than what is the problem? if you say amplification I already have outboard amp and nice headphones. I like the Red Wine audio upgrade but they only do that for 4th gen ipods.

You're the one suggesting surgery to cure (what I could only assume was) a perceived problem.


The only iPod audio problem I am aware of (outside stock firmware's clipping EQ) is the problem the amplifier has with low impedance loads.  In all other regards the iPod consistently tests with the best of them.

I want better man
I dont know im always looking to modify my home system and I have more than $8,000 invested into my 2 channel setup.
Wow I didnt know there were so many nice non-condescending people on this forum.

What would you like to make "better" about your Ipod's output?

(If I may be so bold as to speak for what I perceive to be the majority here)
I think you will find that subjectivists don't get milk and cookies from the primarily objectivist core team of Rockbox.  That is not to say there is any excuse for rudeness, and I am sorry if you feel you have been condescended.  
I still don't understand where you feel the iPod lacks.

The dif between apple Losless and Wav?

No one can do this.

Oh and I want better sound quality

I don't think you understand my question.  What do you want improved specifically?

Also, you can edit posts if you forget things.

Soap:  I don't think this needs any baiting.  

Reid:  Tread carefully.  You seem to be implying a lot of things that will annoy the more knowledgeable posters on this forum.  You might want to do some more reading about audio before posting like this.

Does anyone else think this is a needed feature request? I've suffered without cookies for long enough, and I think there's no reason why an open source product like rockbox can't provide for the needs of it's users.

I'd cook it myself, but I'm too lazy. I think I'll just complain instead.

And yeah im the guy going back and forth between lossless and wav like 300 times with the same song and you will all say im crazy but I heard a difference    

There isn't a difference.  
Lossless and WAV send exactly the same bits to the DAC in exactly the same order.
This is the danger of non-blind testing.  
The objective way to test a situation like this is blindly, as with an ABX program.  I have heard the arguments, and understand the problems with ABXing hardware - but lossless/WAV is a software issue and can be ABXed with 100% confidence in the procedure.

What I wanted to do is bypass the interal amp all together and change out the Wolfson chip for a 24bit unit so I can encode all my songs at  higher resolutions.

The difference between 16 bit audio and 24 bit audio is wholly in the potential signal to noise ratio.
With 16 bit audio you have ~96dB of signal to noise ratio.  That is very widely believed to be the limit of human's ability to differentiate sources.
An audio source with 96dB to play with can accurately reproduce the sounds of a jackhammer at two meters and a person breathing at three meters, both at the same time.  If you think you could hear the person breathing - you still have more bits left.

Im really into super audio and dvd audio discs and im trying to get as close as possible.

One of the problems with SACD and DVDA discs is that they have unique mastering.  Even the dual-discs have different mastering on the CDDA layer than the "high def" layer.  The only way to properly test if you can hear the difference would be to rip a SACD or DVDA's high-def layer and make two encodes - one at native samplerate/bitdepth and one resampled down to 44.1/16.  Then ABX between the two encodes with a good program like Foobar2000 - making sure to resample the 44.1 one back up so that any poor hardware upsampling is accounted for.

posting like what?

And yeah im the guy going back and forth between lossless and wav like 300 times with the same song and you will all say im crazy but I heard a difference           ( extremely small had to do with the drums and synths in a song) that no one would care about but the other guys like me.

Things like this.  There is no difference.  What you heard is called a placebo, and you heard it because you did not properly do a double blind test.  Looking up the definition of lossless before bothering to test would have prevented you from making this mistake.

Honestly I dont know alot about the actual makeup of electronics (internals) Im trying to learn. I mean I own home dac's but if you asked me to open it up and point out what everything was id get like 2 things right.
What I wanted to do is bypass the interal amp all together and change out the Wolfson chip for a 24bit unit so I can encode all my songs at  higher resolutions.

Several things:

1)  24 bit is completely pointless for playback.
2)  You probably don't have any 24 bit source material to encode.
3)  You're not going to be able to add a 24 bit DAC anyway.

Im really into super audio and dvd audio discs and im trying to get as close as possible.

The only advantage of SACD and DVD-A is 5.1 audio, and you won't have that in Rockbox regardless, so upgrading the DAC does not help you there.  

This is really what I was getting at when I asked why you wanted to upgrade the DAC in the first place.  Since you've got a headphone amp, it seems really pointless.  I think you should more carefully consider what you're trying to do before thinking about modding anything.

Im just looking for help and support. What do you suggest we can do to modify the ipod. I saw that you said it would be possible to upgrade the dac and that is why i posted. What headphones are you runnin just wanted to know, not attacking, and do you run an amp?


Oh and check this out
