GALA DAC - New Product, Coming Soon

SMD soldering? I am not up to the task :eek:
Having the option to bypass it with a jumper would be nice.
I would be curious to see the impact on the measurements too: I have a feeling that this chip might not be as innocuous as it seems, even when not asked to do rate conversion.
 
@watchnerd, IMO spidf/AES3 is the right input interface for a future proof product, much more so than USB or any current audio networking protocol (especially in the consumer realm...)

You can use a cheap USB to spidf adapter to connect it to a computer, or a Dante AVIO AES3 interface to make it AES67 compliant (and then you could even power the DAC with PoE as it is a 12V device).

I don't mean audio networking protocol.

Just regular TCP/IP over wifi or ethernet.

My $99 Roon bridge running on a Raspberry Pi has been running without failure for probably about 2 years now.

You can make a high performance room bridge with the ApplePi DAC. I have multiple customers who have done this, and been very happy with it.

I am waiting for Amir to finish his testing of the ApplePi DAC with the balanced output and also ApplePi Volume-Clocker.

We are drifting from this topic, if you have any questions on that please post in the ApplePi DAC section.
 
Did you send a new unit to Amir for testing?
I'd be curious to see if bypassing the SRC4193 chip makes a difference...
 
SRC4193, is that for volume control?

(I do not need volume control in the dac)

I have not received Amir's unit back, when I get it back I will repair it. And then I will test it before sending back to him. This will most likely not happen until early November because I'm not able to get an audio analyzer before October 29th.

I have done the testing with and without the 4193 on a different PCM1794A implementation, and there was no difference. On this design it is not a trivial matter to bypass the 4193, but it should not cause any degradation to the audio.

I already know for a fact that Amir's unit has wrong power supply voltage.
 
If that volume control might affect performance, I also vote for a jumper setting to be able to disable it.
Is it too late for pcb changes like that now?
 
Are you sure the ASRC part of that chip can be completely avoided?
Is it explicitly stated as bit perfect when used with no volume attenuation in your configuration?

The device is configured to output the same sampling frequency as it is given.

Audio performance is not affected, if anything it is improved because the 4193 also decreases jitter from input to output.
 
pos, is it noise or distortion an SOTA implemented ASRC typically adds? Or both?
I remember you prefered your next dac to have ASRC some time ago, referring to Benchmark Dac3. Have you changed your mind about this?
