My X1 power supply is only slightly warm in standby, but I do not have an IR temperature measuring device to quantify. Have you actually measured temperature of yours? I have my power supply to the side of the X1. I have both the power supply and X1 sitting on A/V RoomService EVP footers under the body of each--3 of them under the power supply. They elevate higher than standard feet, but I would guess there is more insulation under the power supply with these than without. Again hand feel only, but my X1 seems similar to my Antipodes K50 G4 in standby. Temps on it can change when active depending on activity of the computers within. Antipodes web control access has monitor gauges displayed on the web interface that shows CPU Usage %, Memory Usage % and Core Temperature for Server computer and for Player computer. Antipodes generally recommends leaving the unit on when not in use for sound quality and for potential software upgrades sent during very early AM hours. The G4 hardware upgrade involved several changes, with one being changing from linear power supplies to switch mode ones. The recommendation for leaving on did not change with this change. Their recommendation also supports in my mind leaving the X1 in standby. However, your unit may be running hotter than mine. I would suggest quantifying the actual temp of your unit and communicating with Lumin, and possibly here, for further feedback. I empathize with your concern on heat. I also have a Mola Mola Makua preamp with DAC. That does run much warmer, hot, than these other pieces and is a known condition. I do power it down when not in use.
