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.
