IPOD & WADIA dock - Anybody ?

Why not wait Wall Mart will have a copy soon at a 10th of the price.

Then I willl sell it on Audiogon, the 3 that are presently listed there are all sold. And Audiogon people don't buy Wall Mart

Hi folks.

Ok. Now I got an impression about this device. Pretty cheap implementation.
What would you expect if Wadia sells these devices at that price level.

But if there is a 2705 inside, there is an I2S inside,
With a bit of reclocking it should make a very decent device. I mean - this has been done
a million times on the 1543 dac-devices.

Assuming the whole output is bit-perfect, a Sabre or a nice reclocker DAC should kill quite some jitter.

When it comes to capacity I think the 160GB Ipods will be big enough for having some fun.

Cheers

More reasons not to spend your hard earned bucks on this over priced docking station.

Quote>Synopsis: Best thing I can say about the 170i is it does pass bits; HDCD LSB code remains intact. First impression was, this is not going to hurt Wadia's high end sales, to put it politely. More directly, it sounded horrible! Pinched, granular, 2-D, not liquid, in other words, typical bad digital sound. As in, reviewers that liked this must either be deaf, or on the take. Maybe the cheap smps is too noisy?

Inside: Rev 3 board, qc passed sticker, 3 or 4 layer board, three 3 pins regs, a couple qfps, and a 28 pin ssop that is probably a 270x...12 MHz xtal at one end, hp outs other end, dout pin 5. Hmmm, the hp outs from the 270x go through coupling caps to a empty pads for a hp jack, and the analog out jacks on the back feed directly to the ipod. Likewise, the video outs go directly to the ipod.

So, the whole reason is to spew clean spdif bits, right? Maybe. The spdif out RCA jack traces directly back to pin 5, as in direct, no passives, no buffer, no cap, no xfmr. Huh!!!???? Confirmed, 0 - 3 v spdif at jack, DC at midpoint. Ermph? Shakes head. Not even impedance matched microstrip/stripline, as the 270x is on the far side of the board, not someplace sensible, like right next to the output jack.< End Quote

I would like to know how to interface a PCM270x to an iPod so I could build my own. Then I could take the I2S out and send it to SRC4192->PCM1794A.

Does anyone have a clue on how to do this?

You would need to built a USB host, to bridge between the two devices. Just another chip.

Sounds complicated.

Maybe I will just stick to the SPDIF out on my iRiver H140; too bad it's so large.
