I still boot by hand on the newer stuff. :-)
I still use a Variac to bring up my MC60s and 225-275 valve amps.. A 20 minute process. 25 vac to 50 to 75 to 90 to 105 or so..
Triggers.. are fancy.. good for HT and multi HD amps coming online..
The pre is in standby, streamer is left on and class ds are left on in the summer.. no need for triggers here.
Turn on the phono/tape pre (at least an hour before use). No trigger there.. No HT, no need..
A lot of NOs LOL.. grandchild... gear.. same thing...
