Allo Audio Piano DAC for Raspberry Pi

I know the 2.1 dac works as any dac would with an rpi and uses same current, but has 4 rcas. It is supposed to be a big increase in sq on other dacs, although cannot confirm that.
Audiohdwr is the owner or rep of allo, and a member, so pm him. sure he can help

I have two questions:

1) Power - 3A
I read the Kali needs 5v/3A... which means I cannot use the Ifi iPower that I just ordered since it is rated for 2.5A, correct?
I guess I know the answer but just wanted to check....

I've been running the RPi+Kali+Piano2.0 off a 1amp regulated supply (TPS7A4700). The Piano 2.1 will require a bit more current, but I'm pretty sure that the Ifi iPower would be more than adequate.
Edit: I just checked the diyAudio thread, where Allo stated the current draw of Kali to be about 100mA, and Piano 2.1 about 320mA. So I've no idea why they recommend as much as 3A.

I tried my Kali Reclocker/Piano 2.1 with my HD-Plex PSU rated at 5v 2a and it ran hot, so I now just use the supplied wallwart until I replace the HDPlex. I haven't tried it without the Reclocker by I might just to see if the DAC runs ok at 2a.

The HD-Plex runs stone cold with just the Pi and IQAUDIO DAC as that only requires 2a max.
