Kubelik NOS DAC kits

[audiostar]

The lingDAC thread is a lot to read. It seems with abraxalito DAC a big bang for the buck. Also read An interview with experienced digital & analog designer Richard Dudley.

 

[abraxalito]

Yes the lingDAC thread is long, but still just a minnow compared to the monster TDA1541A thread started by ECdesigns.

If reading the lingDAC thread leaves you hungry for more background, the pre-quel to it is this one : TDA1387 x8 DAC: let's check its design, mod it -or not-, play music -or not! -

I'd want to buy 3-4dac kits.. I've only read a little of the threads on Kubelik and Ling and other variants.

What's best version to support Hi Res Files? What happens to Hi Res through Redbook 44.1khz?

I need optical and coax input..


Maybe you can give suggestions for me.. Get my feet wet building a few dacs for first time..

I'm ready to order.. Hope you can help

 

[abraxalito]

There isn't any support for bits beyond 16, they get truncated because the DAC chips used are 16bit type, designed before Hi Res became a thing. Which means the very lowest-level signals on a 24bit recording will get lost or distorted. Higher sample rates are fine though.

Optical and coax inputs (S/PDIF) can be accommodated with an interface board.

I sent a prototype of Kubelik to an enthusiastic customer of DecaDAC, here is his report back : lingDAC - cost effective RBCD multibit DAC design

 

[Joel Wesseling]

I was planning to read and conclude on appropriate interface board.. Not sure if this one from PCBway will be compatible.


SPDIF coaxial fiber AK4113 receiver board, I2S output - Share Project - PCBWay

 

[Joel Wesseling]

I guess the Interface board would have to output 16bit, higher would be bad.

 

[abraxalito]

That interface board looks fit for purpose. Do they have stock? I ask because AK4113 has gone out of production as the AKM factory suffered a fire.

Higher than 16bit output would be fine, the DAC chips just ignore any bits beyond 16.

 

[Joel Wesseling]

It's not looking very promising!

 

[abraxalito]

Other interface chips are still in production - you could search on DIR9001, CS8416 and WM8805 to give the three most popular examples.

 

[Joel Wesseling]

DIR9001 and CS8416(QTY=5) available now at mouser!

Not replacement for AK4113?

Thanks for your help. I'm ordering 4 pieces.. I'll order from you too - back in the morning. Thanks again!

 

[Joel Wesseling]

Is this solder suitable?.. There's a few choices so just want to buy right one..
The roll I have now is 0.75mm

[abraxalito]

That's a lead-free type. Myself I prefer the traditional solder including lead, I have almost no experience with lead-free. The diameter of 0.3mm is right for this purpose.

 

[Joel Wesseling]

Thanks!

 

[Joel Wesseling]

How do I interface USB.. Want one dac usb only

 

[commstech]

lead free type is really a bad idea for smd soldering.

 

[Grarea]

I have some 0.5mm.
I would like some smaller too (I think I might need all the help I can get )
I am in the UK, but the only make I know is Kester, which has to be bought buy the lb and brought in from the states.


Does anyone have any half decent recommendations for leaded solder? (at a reasonable price)
It would be nice to have a little range of sizes.

 

[abraxalito]

Here's some 0.3mm 63/37 old fashioned leaded solder on Aliexpress : Page Not Found - Aliexpress.com

@Joel - a USB option :
