Power Supply for Schiit Mani Phono Preamp


I've been reading about linear power supplies and it struck me the Schiit Mani phono preamp that's feeding my Schiit Freya preamp has what appears to be a really cheap power supply.  I wrote to Schiit asking whether a linear power supply would improve dynamics or transparency and they said they didn't know because they had never tried it.

I've got a Well Tempered Refence turntable with a recently rebuilt Lyra Clavis, so I'm starting with a fairly high quality signal.

If linear power supplies dramatically improve streamers, why wouldn't one help a Mani? 

The specs on the current power supply say:  16VAC transformer, regulated +/- 5V rails. Power consumption is 4 watts

If a better power supply would provide a significant improvement, what should I buy?

But but these power supplies *are* an advantage, no matter how Schiit created the circuitry. My, and others who have ears, have heard their advantage first hand. In my case, the performance increase was somewhat substantial. The additional money spent took the very good value Mani to another level. As one reviewer I read stated, ‘his Mani, with the Swagman, made it into a phono pre that easily rivals those costing $500-700’. So still a great deal.

In the end, the performance increase is all that matters for those who have ponied-up the additional $110-130. 

As I believe I stated, I was ready to make a move-up to a more expensive pre, (perhaps much more), but took the chance on one of these power supplies first. There wasn’t really much to lose. And I’m glad I did. That doesn’t mean I won’t replace it, I’m sure I will at some point, but don’t feel that necessity right now.

And I have done a little research regarding ‘linear power supplies’.
Thanks to everyone for the great input.  I shall never mislabel an AC transformer that sort of looks like a DC power supply again.  I'm certainly no smarter, but definitely more discerning now.
bkeske has convinced me the Swagman transformer is definitely worth a try.
Thanks again.
@dougthebiker,bkeske is right on the money about the Swagman Labs power supply for the Mani. I have the Mani in my system for about 6 weeks now and the Mani has never sounded better, it took on a new life as everything just smoothed out, got bigger with more air, soundstage expanded in both width and depth. I more than happy right now with the Mani not to say that I will not upgrade at some point (looking for a ARC PH3) but Im not in a big hurry. Get a Swagman Labs and a descent power cord and you will be amazed how good it sounds. Happy listening and just enjoy the music.
