I leave my Innous streamer, Technics TT, and PS Audio phono pre, DAC, and power amp ON all of the time (except during thunderstorms). When not in use, I turn off my LTA preamp, and 40-year-old Teac R2R and dbx noise reduction unit OFF.
@maprik From the PS Audio BHK250 user manual, “We recommend leaving the rear panel power switch active at all times but placing the unit in its standby mode when listening has been finished. Standby can be activated by pressing the front panel PS Audio logo button, located on the upper left-hand corner of the BHK Signature front panel. When the logo standby button is not lit, the amplifier is in standby mode, and the vacuum tubes are turned off. Standby mode keeps the solid-state circuitry of the amplifier in a reduced power mode, maintaining excellent performance benefits while consuming little power.”
