Project: Audiophile Media 'Brick'

post #1 of 7
Thread Starter 
I have an issue with the DAP's currently available on the market. My problem is I think they all suck.

Sure, the odd company here and there will throw in lossless file support here and there, but by and large these are token upgrades.

The mass majority do not use their MP3 player to listen to music, not in the sense that the audiophile does. Do the audiophile goals of clarity, purity, and quality matter to the masses?

No, most people use their portable media devices as a source of 'white noise'. They do this to block the rest of the world out, so the quality of what is playing could matter less to them. As for the players and their supporting firm/software, they are designed for the "Moron Level" end user who thinks that adding a lowercase "i" in front of a product makes it cool.

So what about the audiophile? We have to perform extensive modifications to these devices and jump through hoops to get software to play our large lossless music files, on top of finding an DAC/Amp to keep our expensive headphones from clipping.

Or do we?

Enter the idea of the media brick.

NOTE! MASSIVE EDIT AHEAD: I made the idea of the Brick WAAAYYYY to complicated, so here are my revisions.



The idea behind the Brick to design a digital music player to fit audiophile needs. To do this it must have a large memory capacity, quality components, lossless audio compatible software, and be able to drive high end headphones.

Your typical portable rig does the following:

Music File---> File Read/Signal out ---> Device Volume ---> Line out to Amp---> Amp Gain ---> Amp Volume ---> 1/8" Jack ---> Headphones

The Brick would do things a different way:

Music File---> File Read/Signal out fed directly into an integrated Amp (Gain/Volume) ---> 1/4" Jack ---> Headphones

This is a more simple set up where the audio signal doesn't have to go all over the place to get to your ears.

So the Brick will have:

1) Open source media firmware that supports lossless files and easily allows the user to organize and customize.
2) A simple LCD screen to see your file organization, select tracks, and see what is playing.
3) A large internal memory source, possibly able to accept external SD/USB memory.
4) An integrated amplifier that receives the signal straight from the player's hardware.
5) A single single point of volume/gain adjustment with the integrated amp.
6) A 1/4" headphone jack, straight out of the amp, for better sound quality
7) A good sized rechargeable battery to power the player and amp.
8) All wiring and internal components will be high-end and well shielded.

This will of course make the device larger, but how portable do you really need a player to be?

Ultra-Portable:

iPod + Amp + Earbuds = A pack of smokes, a lighter, and your wallet.

You can take these literally anywhere you want to go, and use them even while jogging or rock climbing if you wanted to.

While they would be easier to carry in a bag or backpack, you can fit these in your pockets with out too much hassle and could even carry them around all day if you had to.

Portable:


Portable CD Player + Amp + Full-Size Cans = A book, your wallet, and a bag lunch.

You can take these with you literally anywhere, although you wouldn't want to go jogging or rock climbing with them. You can easily take these with you if you have a bag or backpack and could easily carry them around for a while if you had to.

While the Brick would be a little larger than a CD player, this would still fit most audiophile needs.

Anyone up to giving this a try?

Those myvu glasses would be a little ridiculous for an MP3 player. You could just get a netbook and reverse the screen so it faced outwards and then add one of those ebay touch screen kits.

It's kinda hard to justify something like this though. How often are would you be able to appreciate the sound quality difference between the iPod headphone out and a higher end dAC and are willing to play it out of a book sized device but can't just open up a netbook and hooking up a gamma2? The difference in quality probably wouldn't be that noticeable in a plane, car, or train because of the background noise. If you travel a lot it would make sense in your hotel room but you could just use a laptop instead. Even then, an iMod and mini3 amp make a pretty decent combo that doesn't cost a whole lot and is pretty portable.

One thing you might want to look at is the hifiman: Head-Direct.com | YUIN

Most of it has already been done for automotive use. Lots of cool stuff very small size even specialized versions of Linux for a dedicated player interface and 7" touchscreen monitors.
Me I use my iRiver or notebook.

I want to see this but with smaller components: cMP² | CMP / 05Components . With also the same type of efficient software of cplay/cmp. Actually if possible it should not even have an operating system just the player software like rockbox but modified to do the things like cplay/cmp. I'm a little worried that PCI may be a little too big for portable use though, and that we should look at other sound card types, maybe even completely new DIY boards. I used to joke around that they should make a giant ipod, looks like that's what you want .

Seems like you're pretty much describing the Hifiman 801 -- do you have one of those? If not, get one, and see how would impove it.

As long as you're talking strictly audio playback, you might be able to use something like this:

Arm S3C2440 Developing board 7" LINUX windows CE SKU06 - eBay (item 330350042418 end time Nov-02-09 18:51:11 PST)

If you ran a real "barebones" OS implementation it might actually work.

What you're describing in the revised idea is essentially the iMod to a Fiio or mini3. The iMod taps the lineout directly from the iPod DAC before the volume control or opamps and feeds it out to the dock where you can attach an external amp. I've been using that for a while and its very decent.
