Esoteric CD Players - Standby mode?

I own an Esoteric UX-3SE and have noticed that there isn't a "standby" mode whereby basic power supply and such stay powered up so that the unit is "ready to go " in a few minutes after turning on. The unit gets dead cold when you turn off the front and only power switch. I assume the 5's and 1's are the same way.
Do you other Esoteric owners leave them on all the time for best sound and just turn off the front display?
I welcome your thoughts and input. I emailed Esoteric and did not get a response. That surprises me.
Thanks!
Bill
