About PSU, I use 3xLT1963 Chinese board ( Mod Mundorf cap 10000uF ) supply to Mezzanine board for Pi3.
Mezzanine Power board<br>for Raspberry Pi
For Katana, I use a Teradak LT1083 fit to USB type C of MC board. I want to check how V1.2 sound as Allo defaut recommend about PSU.
Lasttime for Katana V1, even I use 3 PSU for stacks : 2x5V LT3045 for DAC and MC, a +-15VDC Salas UltraBib 1.3 for the Opamp, Mezzanine to PI3, it sounds less detail and funny than Katana V1.2. I also got very bad smurf sound because onboard +-15V regulator failed and disappear about it.
But, now I hope after weeks burn-in, V1.2 should be better. And I like it very much.

But a renew product from Allo and their way supporting customer make us acceptable enough after more than 3 months wait and wait....

I am very glad to hear Anhton , sorry for the delay , but we took the time and tested , retested and then compared our findings with more testers.. (looking at you Greg :-)



We simply wanted to get it right (SQ) and its not an easy thing to do.

Do you have a reference DAC Anhton ? Can you compare it with your reference ?

I compare to Katana V1.0 and Boss Dac that what I mean. I also used Marzant HD01 DAC before.
