I got a little Schiit Mani would it benifit from an iPower low noise power supply?

I like this little Shciit, it's far superior to the P5 phono stage.

I also asked Teac if I should use on my TT and they said NO NO NO. I think because of the warranty, or maybe because of the higher amps. I don't remember what they said outside of just "NO". I asked guys too, and I don't remember what y'all said either.

Thanks
