DAC AK4499EX Project

[piglet11]

Project of chassis in progress 🙂
Now I am waiting for parts form laser cut. Chassis will be in good old times style like Japanese company when accountant does not wathing on the project. Copper inside, wide and heavy aluminiom cover 5 mm and frontpanel 15 mm of aluminium 🙂

I'm monitoring this thread with interest!

Fitting 🙂

Are the pcbs available to purchase?

 

[Dhananjeyan]

does this design implement the ak4191eq?

 

[Dhananjeyan]

just saw that you will only sell populated boards if so could i choose my own individual components as i want to use top of the line components such as Vishay z foils.

Finally chip's came to me from @acko 🙂 Thank You!
Commissioning mode is on 🙂

 

[AnAudioPerson]

Do you have any pricing expectations?

 

[piglet11]

First chanell is working!
In next week i will have stereo 🙂

 

[piglet11]

Stereo is working 🙂
Now I ma waiting for second transformer.

Eco version for my new DAC in progress 🙂

 

[dch53]

How many layers do you have to use to route something like that?

 

[piglet11]

4 layers is enough for DAC.

THAT is amazing 😉. Just reminded me of that im a part of the westwood audio project, (M-audio etc). He has used more than 10 years now 😉

Congrats

MDAC, Westlake. Stop the time!

BTW will it ever be created?

 

[piglet11]

The chassis came with painting 🙂

4 layers is enough for DAC.

Sometimes even 2 layers (with good results).

(However, 4191+4499 I did in 4).

In old chips I agree. 4 layers board now are cheap and is easier to avoid crosstalk and do Your layout better. 🙂

(However, 4191+4499 I did in 4).

Can You tell more about Your project?

 

[altor]

In old chips I agree.

Not only, I susscesfully made in 2 layers AD1862, PCM1792, AK4490/93/95, BD34352, etc.

Can You tell more about Your project?

I hope it will be with more details in July.
It is one of the modules of my ATDAC-11 project: https://www.altor.co/products/audio/atdac-11
Briefly: AK4191+ AK4499 + 2xOPA1632+OPA1656, powered from LT3042, TPS79318, LP5907.
PCB is 85x60mm, 4 layers.
All other things (power, USB/SPDIF inputs, Control) are located at the universal main PCB.

Unfortunately, I'm too busy with other things, so I only made 2 pieces, which were sold out (one sold, the second was a gift to a friend).
That's why this module is still not presented on my site.

I making a new PCB revision now, due to the some changes which were made manually in the 1st revision.
