The LPS -1 improved on an already very quiet system when it replaced my iFi power supply powering my microRendu. Initially I heard a slight reduction in dynamics, but that went away within a few hours. From the beginning the LPS-1 created an incredibly black backdrop to the music, I am very happy with the purchase.
For reference, the LPS-1 is powering a microRendu which is feeding an Auralic Vega, a sonic transporter is running Roon, music is on a Synology NAS and Tidal. This all feeds a Bottlehead Kaiju with the DC filament conversion, Elrog 300Bs,GE 5 star 5670s, Clarity MR and Jupiter copper caps; this drives a pair of GR Research Wedgies with the foundation supplied by a pair of servo subs in OB per side each with its own servo amp. All power runs through a PI Audio Uberbuss, the RCAs are High Fidelity CT-1s, Morrow Audio SP5 speaker cables, TWL and stock power cables.
