Linear power supply

I understand your node responds well to an LPS. I added an Sbooster with the Ultra upgrade to my Qutest, with nice results. chatGPT is very high on the iFi SMPS & its very low noise. I have ordered one for my TT & one for my miniDSP.

For my Bluesound Node 2i, I went with a dual output multi voltage selectable  Keces LPS. through Power Holdings. Good guy to work with. Caught mine on a good sale too.

Use 2nd output for my external DAC. A noticeable upgrade to the Bluesound.

I think I got the conversion board from that place in Poland. TPs boards would not work in mine, but they made very fair refund.

Sbooster. 

I have an older BS Node N130 and I bought a Teddy Pardo LPS.  It really made a positive difference.
