I have to say this has become a really interesting thread to read. This being our hobby all of us are into it and have deep seated opinions that we believe. I have spent the last hour reading the posts here. Such a great read so far!
My 2cents..................................................
As I posted before as an answer to the OP's question. Yes, every Apple product sounds a little different. I ask people to understand this in simple terms due to each Ipod having it's very own special DAC.

You can clearly see on the list of products that they have different chips affecting the signal.
I am a very consistent Ipod Touch user and greatly enjoy the intimacy resulting from not using a secondary amp but just use the Ipod out listening process with no EQ. My favorite Apple DAP has actually been the 1st generation Ipod Shuffle. Those things being low in music capacity as well as simple in user interface lack many features which we have become used to with the Touch.
Part of the 1st generation Shuffle sound must have been the result of the Wolfson DAC they implemented then. Interestingly even today here at Head-Fi you have a small cult following for the sound of the 1st generation Shuffle. In my history using and experimenting with Apple DAPs the sound break-through as upon discovering the boost that a Rockbox software improvement could due to an Ipod mini. The new fact that the Apple Ipod mini can now have user replaceable batteries and upgraded bigger memories as well as Rockbox makes them amazing. I do have to say that still my admiration of the sound of a Rockboxed Apple mini could only be from the increase in volume production. I truly just don't know? Loudness is really funny as a SQ placebo that way.
Finally getting and falling in love with the Cirrus Logic C42L63 direct out-put on an Apple Ipad 2 let me know that Wolfson was not the only Apple DAC I could get into the sound of. The Ipad2s get really loud. Louder than the Touch ever could! pure power there. To reiterate the concepts posted in this thread, all Apple produts do come close to CD quality and yes have a very close to perfect un-colored flat signal out-put. They all sound great! Still each one has it's own tone.
I do have some personal ideas and have a new DAP plan for 2013. No............ an 5G Touch is not in the cards. I agree they maybe sound as good as some of the other Ipods and have a list of features that make them very special in the marketplace. Still for listening to digital I have doubts about the jitter coming from USB computer audio and feel a stand alone 16 bit CD player still slays all other forms of digital playback. The main reason that we are seeing a big uptake in 24/96 vinyl recording played back on the computer is that they do help some systems to sound better. Still a good old fashion high quality 16bit /44.1 DAC signal coming out a a nice CD player sounds way more natural to my ears. Every year I feel more and more that this is a true fact and the downfall in USB interfaces. Optical could maybe fix that but I have not played around with it enough to say for sure. USB is USB, it is what it is.
This all leads to my next personal audio chapter. I purchased a Samsung Galaxy Tab 2 7.0 tablet. This was mainly due to the ability to play a range of high rez digital audio files. I can play FLAC as well as big vinyl rip files on a portable. The European Samsung Tab 2 7.0 tablets are a phone model GT-P3100 and have the fabulous WM1811 DAC made by Wolfson. I will be attempting to test different playback software as well as different headphones to find out where the best sound is at. There is also a small handful of Galaxy Tab users getting ICS (Ice Cream Sandwich) and the new Android Jelly Bean 4.2 operating system to send USB digital signals out to outboard DACs. LOL, back to USB hell?
Still direct out is what I'm after. Just the DAP and some headphones.
With the news of 7 carriers offering Samsung's new phones at the end of April you can see the starting of bigtime success for Samsung. The only sad part for any of us changing off away from Apple ends up in the simple powerful use of I-Tunes as a great organizer of music and file transfer. Still with the added benefits of simple things like replaceable Samsung Galaxy Tab 2 7.0 batteries makes you wonder if a long term commitment to a new file transfer scheme could be worthwhile in the end.
