Been reading every post on this thread and am excited to have finally decided to get the Katana to replace my HiFiBerry Digi (PCM Out)/SMSL M8 DAC (External ES9018) setup. Like others, I'm patiently waiting for release 1.2 to start shipping. Meanwhile I'm trying to get my ducks in a row in regard to my power supplies.
Currently I use a linear PS I built with +5V and +9V output to power the RPI and my DAC, but going forward I think I'm going to go with three PS: A cheap, regulated 3A for RPI, my +5 linear for MC (+Katana and OpAmp), and then build a linear +-15V for the OpAmp board. Two questions.
- I didn't see any definitive specs on the +-15V. Would 1 AMP each do?
- Is there a compelling reason to supply separate clean +5V power to Katana and another one to the OpAmp? Their usage is so minuscule that it seems like a waste to spend (build, in my case) two separate linear +5V supplies. I can't see them introducing fluctuations to the power coming from the MC.
Thanks,
