Question ESS Sabre ES9012, ES9023 or Wolfson 8741 ???

Hi folks !

Which of these you would choose, based purely on audible sound quality?

Although ES9023 looks like lower-end ES9006 (compared to ES9012) with integrated op-amp, I'm not sure that difference is really audible.

I'm going to construct and assemble PCB myself (with USB & SPDIF and possibly i2S). Schematics seem to be very typical and are freely available without royalties.

Another option is Wolfson 8741, which have clear advantage - availability of open source Linux drivers. On paper ESS seem to be better, additionally, ES9023 requires simpler PCB.

So I have a dilemma :-)

Thanks in advance for sharing any ideas and experience.

What drivers? That is just a DAC, without an USB or PCI interface to require "drivers". I think that you are mistaken it for another WM... 8804 maybe?

Linux ASoC libraries, look at

WM8741 Linux driver released | Open Source at Wolfson Microelectronics

From the Wolfson web page:

The ALSA System on a Chip (ASoC) subsystem provides a framework for audio in emedded systems running Linux. It provides a framework allowing reuse of support for individual system components, providing support for minimising power requirements based on the currently active components.

A system using ASoC is represented by a machine driver, specifying which audio related components are in use in the system and how they are connected to each other (currently PCM, I2S and AC97 are supported). The ASoC core then uses this information to provide a sound device to the system with the combined capabilities of the devices in the system. The interconnection information is also used to provide dynamic audio power management (DAPM) - only those components required for the currently active configuration will be powered up, with the core providing algorithms to reduce pops and clicks as components are powered on and off.

I think that is a very cool piece of software. Thanks for pointing it out!

Out of interest, what device are you using for i2s source?

I will use embedded Linux powered with ARM.

So... basically useless, since this is a DAC that has a "hardware mode".

But you don't have access to some interesting features in hardware mode, including two of the more interesting filters in 44.1kHz mode and the internal 32-bit volume control.

Meah, IMO volume is best done "ouside" of digital domain.
Plus, a software it is not a "driver", if that device does not connect directly to a PC bus (like PCI/USB).

Not useless if you're connecting directly to a SoC.

Quite useless if you are connecting via spdif/usb/intermediate interface.

We're way off topic, my opinion is that the es9012 is a better device, not forgiving if you are doing a quick and dirty diy implementation, probably quite rewarding if you have the time/knowledge/equipment to go over the top with your implementation though.
