Advantages with an outboard power supply

reading some articles and watching some YouTube videos and they say it will not help a digital signal.

Of course it can help a digital signal. An LPS is replacing the stock power supply of the component. If it’s well matched to your device, expect to have a lower noise-floor than SMPS, lower ripple effect, more reserve power.

I’ve used one on a dac and a reclocker.

Farad build look very impressive. Their build menu is nearly that of Cheesecake Factory.

Small Green Computer has LPS at a good price.  

So I bought a Bluesound Node N130 and ran it to a Denafrips Pontus ll DAC.  It sounded great.  I bought the Teddy pardo power supply and it really sounded better.  Any time you buy an economical all in one unit like the node, the company has to save money anywhere they can and a switching power supply is really cheap to make and that’s why the TP power supply sounds so much better.

All the best.

All good information. Thanks Gents -
