Power Supply upgrade for my BlueSound Node N130. I did the PD Creative first and it made a significant difference. Then I saw a picture of the LHY board covered with capacitors and decided to upgrade again. This upgrade also made a noticeable improvement in sound quality. Both upgrades are highly recommended depending upon how much you want to spend.
Prior to the upgrade, I felt that the Node sounded flat and lacking in top end compared to my CDP to the point that I couldn’t listen very long without getting distracted. The Node with the upgrades still doesn’t match my Raysonic tubed CDP, but it is much closer, and I can enjoy listening for extended periods.
