AK4490 USB Dac with dsd support.

[pinnocchio]

So here's my test setup for this very nice AK4490 DAC

Using AMB Sigma 22 Rev2.0 for +/-15Vdc and Sigma 11 for +5.5Vdc. I plan on using R-Core transformers and DH-Labs silver interconnects when finalized. RCAs will be copper with Rhodium plating.

Here's where I will write the review on the DAC once all listening tests are complete for the write up!

Mirand Audio AK4490 DAC DSD

I've already played some 24/352 and DSD 64/128 from mi Pi 2 to test and quickly in 10 minutes I can tell it sems to be a really good DAC.

I will update my thread on the forum so stay tuned!

Thanks
Do

Awesome work Do! I've been away for work, but travel back today. I have the Mirand with a Reflektor-D & SS03 waiting to play with this weekend.

Sorry i do not know... What is an SS03?

Hi Sonny,

SSR03 is a regulator that was created by a DIYaudio member. Never tried one but supposed to be very high end.

Here's the thread

Ciao!

Cool! That should be pretty good!

Let us know how you like it

Thats a very nice display you got there. The pixel pitch seems to be very fine.

Very nice build with SSR03. And I was wondering what this Green board is. It is in Red colour now 🙂.

Let us know what your experience is 🙂

Mirand Audio USB DAC arrived safely 🙂

THANKS Sonny. Your dac arrived safely at my doorstep this morning. Packing was super and the Hammond box actually looks really nice. Listening has to wait 🙁 Got muscle cramps unpacking my jewel and had to go back to bed... Thanks again 🙂

Finally it works with an display controller acting as an i2c slave. But i found out that xmos xs1 does not support clock stretching!!!!!!!!!???[emoji19] come on!!!!

But it switches between the different modes without problems.

What would clock stretching allow you to do that you cannot do at present?

Thanks

I have using the dac about 50 hours now and think it sounds promising good.I use now a Meanwell MW RT-65C as a power supply,but plan to try a toroidal transformer with the TPS7A4700 regulator power boards.

I would love to hear what you think in detail.

I2C is the bus used to communicate between peripherial invented by philips.

It is used between temperature sensors, accelerometers, DAC, ADC and so on.

But it is not the same as I2S. But I2C is used to set parameters in DACS and ADC, or in industrial DAC and ADC to read conversion.

Regarding front panel:

I am testing the remote tomorrow. If this works in the software, i will lay out the display the front panel.

Is active preregulation really recommended or is a decent filtered linear supply what you recommend? Regs on regs can stir up oscillation and stuff so I'm not so keen on it.

 

[ljufa]

Hello Sonny, good work. What dac functions you can control over i2c? Volume, filters...?
