For what it’s worth, you can find my impressions and others’ as well with regard to LPSs for the EE8 in this thread, beginning with post #26 or so. I use a Paul Hynes SR4-12 with mine and continue to feel it is a worthwhile investment to use with the switch. However, I admit that my entire music system and networking components all have dedicated 20a lines and linear power supplies; it also utilizes isolation transformers (both balanced and so-called ultra-) and a double-conversion true pure sine wave UPS feeding everything upstream where the streamer, DAC, etc. resides, which then all goes into a PS Audio power regenerator. I am a huge proponent of theoretically ridding one’s system of as much noise as one can to achieve as quiet a system as possible, and I anecdotally perceive LPSs to be a necessary tweak with the right equipment.
