Hello again Chuck

Looks like we have another equipment in common. Mine's the newer MU3100. But I have not mod at board level yet.

Didn't like the sound from the TVIX. I'm using its digital coaxial out to for connection to an outboard DAC. Had a Sarotech 2.5in HDD Player as a comparison, the Sarotech sounded better. I figured the 3.5 in HDD was vibrating too much (from the spinning) and giving off too much heat. So I replaced the 3.5in with a notebook 2.5in (using an adaprter) and took off the fan. Now it sounds much better. However, the 2.5in HDD is hanging loosely in the original casing. There is still a little vibration from the 2.5in which I will be looking for some rubber bungs to secure the HDD in place and isolate it from the case.

So far the sound has dramatically improved. Its more defined now, not muddy and hollow as before.

Edraket,

Flash memory? I'm waiting for the SSD to come down in price. Maybe next year huh. With SSD, it will be truly vibration free source. Right now its on hard disks (but the 2.5in instead of 3.5in) which has less vibration.

I'm playing music off the this modded TVIX and it sounds better than a regular CDP. (I'm using a NAD 515 BEE for comparison.) The sound is more defined, less muddy.

In comparison to the Sarotech 2.5in (palm size device) the TVIX sounded more fuller. The Sarotech being slightly shy on the bass. Overall, I'm pretty happy with the results.

Got both SD adapter and a CF to SATA (from ebay) for the DVICO(TVIX) and the Sarotech and both dun seem to work. Both the SD and CF card works on a regular USB card reader but when I stick them in their HDD adapters, the music players dun seem to be able to read the flash disks. Any ideas?

And the sound is the best I had so far. It was a big jump in quality when dropping the cs8414 and go I2S direct.

Here's a pic. Everything in a wooden box.
I have a question about this interesting mod: do you have schematics for this board or you reverse-engineered it?
Btw does the tvix have its own "audio" clock?

Cheers

Default Pinging ChuckT

Hi Chuck,
in case you missed the question: how did you find where to tap I2S from EM8511?

Did you manage to get a datasheet?

Cheers

Andrea

It is all related to the DAC used.
For multi-format DACs you should also know how are programmed the mode selection bits.

Too bad there is so little info!
If IIS not available there is also the (worse) SPDIF output.

Cheers

Andrea

Default TDA1541 i2s with WD mini

Just thought I would pop in and contribute.

I just hooked up my WD TV Mini Media Player ( WDBAAL0000NBK ) to my Analogmetric TDA1541 DAC using i2s and so far I think it is at least as good as my usual source which is a fully optimised CMP + Cplay computer with teralink x (1) USB>i2s converter. I tentatively think the WD might be better. I heard more details and better decay of sound, and HF sounded like it went higher and clearer.


I checked the i2s lines with my CRO and I find the signals to be very square with no ringing or overshoot. This is very promising.
I will do more testing tomorrow.

I got some tips with doing this from here: http://community.wdc.com/t5/WD-TV-Mi.../DAC/td-p/5259

The only thing disappointing about the WD mini is the lack of gapless playback.
