Orchard Audio ApplePI DAC review

The production DACs provide the option of powering RPi and DAC either separately or with a single supply. Mine didn't give that option so initially I powered the combination with a single iFi iPower supply. I heard a very well-resolved ,spacious and detailed sound with firm bass and extended treble. The downside was that it was just a bit fatiguing to listen to on some material and front-to-back depth was a bit limited.
I then realised that I could power the RPi and DAC separately by stacking my IsolatorPi in between them. The combination of separate supplies and isolation definitely improved things to the point where I was preferring it to my current fave, the Terraberry DAC2. Adding the Allo Kali to the stack was the icing on the cake but of course the cost of that whole combination is then in Katana territory.


Thank you very much for your feedback.

In the future if you have a chance please also take a look at the ApplePi Volume-Clocker (https://orchardaudio.com/applepi) which adds HW volume control and re-clocking to the ApplePi DAC or to any other I2S DAC or Amplifier.

Yes you can use the Allo Kali with the ApplePi DAC, but that will not get you HW volume control like the Volume-Clocker

@orchardaudio

Can the HW volume of the Volume Clocker be controlled from the UI of Volumio, or only from the onboard pot?
RPi 2b // Terra-Berry DAC2 // Hypex UcD180 // Bi-amped OBs with Visaton B200, Goodmans 15", Neo3 tweeters.

Only from onboard pot.

Can I use my 5V 3A stabilised power supply instead the required 5.25V?

You can try it, as long as you are not powering more than just Pi, DAC and Volume-Clocker.

Biwiring the power will also help, with something like this:

Starting to get some feedback from kickstarter backers:
Kevin:
"ApplePi DAC is an excellent DAC. Compare to the Audio Note DAC 3 I have, it has much more detail."

A little question :
How did you make it "loosless" with any dac i2s? (from my many tests, the lossless subject is very important to my ears !)
But I have a very good attenuator in my amplifier, so, this point is not so important for me.

Perhaps I'll test it with Kali, and perhaps too without output opamps, and with a Sowter 1465 instead.
Output transformer dacs work very well in no-feedback amplifier systems, for my ears...

And for my experience, I think that the lack of " in PRaT" is more due of the use of opamps than a clocking issue.

best regards
