power conditioner with off switch

I use tube amplification so having a power conditioner that (a) cuts the mains power completely and (b) offers sequenced on/off cycles is a must. I've had a simple, cheap Rotel RLC-900 (about $200) for years and though I'm sure there's better out there, I've never had a reason to upgrade. It does its job competently, reliably and without fuss. I've also never been able to hear any sonic downside to using it having compared the sound of various components when plugged into the Rotel and then directly into the AC socket.

Shunyata Hydra-4 and up have on/off switches

why not just disconnect the power cords from a line conditioner ? i just turn off each component when not in use. my power conditioners, ps audio power plant and adept response, have on/off switches.

Sound Application, Blue Circle music ring, and Dodd Audio all have an on/off switch. May be handy if your gear, such as a DAC, doesn't have a power switch.

Torus has separate banks that can be turned off individually. Switches are on the front for easy access.
