Upgrade from modified Bluesound Node 2i and linear power supply (LPS) ?

Wow! I really appreciate everyone’s input!  I’m planning to purchase another Sbooster for the BS Node 2i. The first one is on the Qutest. I think I’ll wait for the chip shortage to sort itself prior to moving to another streamer platform. Plus I want to hear the improvement a LPS can do for the board upgrade modification. 

Thanks for the input!

Jss49- I should have added that I use a Chord Qutest DAC via coax digital output from the Node 2i using a AudioQuest Carbon coax digital cable and then Cardas Golden Reference Interconnects from the DAC to a Cary SLI-80 integrated amp.

Audiotroy - FYI, not trying to debate, I only know what I’ve read regarding USB vs SPDIF inputs.  The engineer/designer of my DAC has posted in a different forum that in general the coax digital input is the best input for top audio quality on his DAC.  He’s not the only engineer who feels that way. There’s also an audio engineer who occasionally posts in this forum and has posted that getting top sound quality from USB is difficult.

Sbooster installed on Node 2i. Used a long-unused Shunyata Copperhead power cable for it. I expect a 100 hr burn-in required for the Sbooster and more for the Copperhead but I’m pleasantly surprised at how good it sounds after two hours! It’s already better than the Mean-Well SMPS.   I wish had done this sooner.

For anyone who cares, use the yellow tip pin adapter #1 from the Sbooster connection kit if you installed the PD Creative power board modification. The black tip appears to fit but is actually quite loose compared to the proper tip.

Again, thank you to all of you!  This is a great forum!
