EnzoTen over at Anythingbutipod.com already open one up for everyone's viewing pleasure (read it here). I can tell you right away the Fuze's SoC is AS3525 made by Austria Microsystems (same as Sansa Clip). If you are interested in learning more about AS3525, I do have a copy of its data sheet here.

First soldering then...

Thanks,
Which conn. did you get from Ridax?

Hey Clie

Is it possible to make a Fuze - ipod adapter? Could you put an ipod dock on the other end of your cable?

I have a quick look at iPod's pinout, and I think it is possible to create a male(Fuze)-to-female(iPod) connector just to get the line-out signal. All you need to do is wire:
1) Pin 27 (Fuze) to pin 3 (iPod).
2) Pin 28 (Fuze) to pin 4 (iPod)
3) Pin 29 (Fuze) to pin 2 (iPod)

What is that yellow fluffy stuff on the inside of the cable? By the way, this is looking at an E250 cable. The sheathing colors are also different, but I'm sure this doesn't matter.

I am taking a wild guess here but I think those fluffy stuff are the damper material in your USB cable.

Clie, how is the DAC quality of FUZE? It would be interesting to have a direct comparison between fuze LOD and ipod LOD using the same amp.

Fuze's DAC is integrated in the AS3525 chip (as part of the SoC). I can only tell you its spec:18bit with 94dB SNR (‘A’ weighted), Sampling Frequency: 8-48kHz. Since most of us (including me) think Fuze sounds pretty good by its own, I guess the only logical conclusion will be the DAC is pretty good as well.

Thanks for the writeup. I've been meaning to try this, but nobody made a pictorial guide. I'll probably buy a connector from ridax and try this soon. I personally don't care if there's a significant difference or not. I'm just craving for a project and I'd like to see how a line out sounds for once (true line out or not). If the line out pleases me, I might even jump into more expensive amps. I've been holding off getting a more expensive amp since I don't have anything with a line out.

So umm yeah... I was bored tonight and I had an extra SanDisk USB cable lying around so I tried this. Anyways, it's not as clean as ClieOS's but it still works. Thanks ClieOS for the visual DIY!

My USB connector was a bit different. The wires on my USB cable were much thinner and were super glued to the board over the soldering points. I pretty much just cut the ends off of those since it would've been pointless to use them. My wire stripper also doesn't strip wires as small as the ones that were found on my USB connector. So I ended up using my own cables.

This also means that I lost the stock stress relief so I guess I'll just have to be extra careful since I don't really have anything similar right now.

Anyways, here's a picture of mine. I used some Canare starquad cables that I had lying around and a Neutrik plug.


My personal opinion is that the amped line out sounds fairly different from amping the headphone out. The details are a little more apparent and the sound is a little more neutral. I think I can actually hear how the amps are supposed to sound now. I did this mod thinking I wouldn't really hear a difference, but they definitely sound different at least for certain songs.

Hi

That's curious.

When you did your comparison, did you make sure the headphone out volume was 100%? When I did my comparisons, from the Griffin Dock, Woo3/650s and M^3/880s, the headphone out at full volume sounded exactly the same as the line out of the dock.

Which amp/headphones are you using?

Yeah, well I've been amping the headphone out at 100% for a while now so I know what it sounds like. I mean, the difference isn't night and day, but I do hear a difference between the two. I wasn't expecting to hear a difference though.

I've tried it with everything in my sig. So e5>sr325i/es7 and pa2v2>sr325i/es7. The biggest difference was when I hooked up the e5. Amping the headphone out, I already noticed that the pa2v2 sounded "better" than the e5, but when I amped the line out the difference was even more apparent. I feel like it made my pa2v2 sound "better" and made my e5 sound "worse." Not sure if that makes any sense. lol

Of course, it could all just be a mental thing, but I'm almost positive it's an actual difference.

Can you comment on the soundstage and transparency? Was there any effect? Do you notice any separation of the instruments?

ClieOS - Big Thanks for the clear instruction!

Curious.... low impedance Vs high imp

I have two docks, one in my office and one at home. Tested them both with the same results. Headphone jack had the cleaner signal.

What mini to mini are you using? I used a nothing special DIY I made last year.

What you see depends on what you're looking for.
