IFi Zen Stream with Qobuz

@temmple 

12 volt is the sweet spot for the power supplies.  The barrel is 2.1 and pin one is positive.  Don't know anything about the brand with the link you supplied and I just stuck with a brand I had experience with.  Most of the ones you buy on Ebay you can just buy from Ali Express for less with quicker shipping.  Don't try to get to cheap.  Don't have to spend $299 but there is a lower limit too.

Agree with @jackd to spend a few more dollars on a reputable brand to minimize the risk of potentially damaging your equipment. 

@jackd So center pin of barrel is positive? Thanks for all of the info here. Very helpful.

Think I found the one I want. Will pick up two. One 9v for the Aune X8 DAC and one 12v for the ifi Zen Stream. Look like a good option?

I am using a 12v SBooster with my ZS. I know, it does not make sense because the SBooster costs almost as much as the ZS, I told my dealer it does not make sense when he suggested it, then he connects the SBooster to the ZS…. and after 30s, I bought it. I do not know if a lower cost power supply can have the same effect but I can confirm that the ZS responds very well to a better PS.
