Would it be possible to stack something else like, digione, usbridge?
No not possible. This is a big stack (3 floors already)
Katana needs power..almost 750ma /5v
What is the power rating on the new smps ? can it power the pi plus 3 board stack, or is it better to power the pi separately , using a superior power source for the control/dac/output.No not possible. This is a big stack (3 floors already)

So 600mA from isolator is not enough 🙁No not possible. This is a big stack (3 floors already)

Does it us less power when conected wit RCA only?

3A

Isolator can supply more than 600ma , in fact at 800ma should have no problems
Isolator adds more cost (board $55 + batteries etc), so does it provide real benefit? The control board already has a usb C socket so presumably can power the 3 board stack independently of the pi ; there are a lot of variables here. From the testing do you get a sense of the optimum configuration that is going to provide the best sound quality.Isolator can supply more than 600ma , in fact at 800ma should have no problems

We are nearing a new isolator board to be used with our Katana that is passive (takes power from above stage) and its much cheaper.
It can only be used with Master Dacs (our Boss and Katana)
Right now it sounds best with 2 PSUs , one for RPI and second for Katana

That HAT tower becomes a skyscraper. 😀

OK. That would be expected. We've been reporting this for... ...actually since the beginning of HAT DAC times. 😉 That applies to all HATs. And usually the lower the HAT quality the more they benefit.
I don't want to stress that usually even a third supply - if possible to apply - for e.g the analog output stage might be well worth an investment.
Anyhow. Now you guys are launching the premier league for HAT DACs.
Pricewise and hopefully also performancewise. We'll see. 😉
Great developments.

2 high quality power supplies or HQ on the Katana only. With an isolator board in place the pi should only require the standard ~$12 Also smps? and the Katana would be powered by the new smps?We are nearing a new isolator board to be used with our Katana that is passive (takes power from above stage) and its much cheaper.

We have a 3 and a 4 way 🙂
Are you able to select from the 7 different PCM filter modes provided by the 9038 dac chip?
Yes from driver (rpi) but also possible to chose a few direct from HAT (with jumpers)
If it can be supported in software(Volume etc..) that would be great. Any estimates on pricing of the new smps yet?Yes from driver (rpi) but also possible to chose a few direct from HAT (with jumpers)
hi, interesting approach!
will it be possible to select source from different inputs? ie: RPi vs SPDIF/Toslink
Thank you

@cdsgames,
Is Allo going to be providing Tim Curtis (Moode Audio) with a Katana sample so that we can be sure that it is fully supported by moOde from initial availability?

How is the new isolator board progressing? Is it possible to now give a preliminary description of the whole stack, placement of connectors (usb c, power headers, jumpers etc.) on the boards and any other options in the configuration of the final player.We are nearing a new isolator board to be used with our Katana that is passive (takes power from above stage) and its much cheaper.

Yes of course we will
