Hey Tim,

You're absolutely right: at the beginning you don't need to spend precious money to these expensive PS (December is already an expensive month, with all these presents…). In my case (I bought the plug and play version) it came with a PS adapter (5V/3A) which I don't even use. The Katana itself will give you better sound compared to all other RPi DAC's, even without the "perfect" power supply. Start small, grow big....later on you can always improve the sound slightly by getting a better PS.

Besides, if you don't buy the Isolator, one simple PS will suffice (cfr. Tim Curtis).
I'm using a USB charger for now, you can always use a decent powerbank as well.

In any case, if you want to profit from the 10% discount Allo is offering now, I wouldn't wait too long to order.... :-)

I received my Katana (SQ stage + isolator) on new year's eve and have been doing some burn in since then playing back a 4000 tracks playlist.
I also tried for the first time to play some DSD files (downloaded from http://www.2l.no/hires/) but all I 'm hearing is noise. Are there any specific settings in the Audio or MPD settings that I have to adjust?

The option DSD over PCM (DoP) can be on or off.

The 352.8 KHz sampling frequency also gives noise here.
One thing though: don't use the slider to go forward in the song, it doesn't always responds correctly. And give it a few seconds (2-5) to let the music start (I think buffers have to be filled first...)
