Does it matter which component I power up first?

I have a Jolida 502brc integrated amp, Jolida J9 phono stage and Origin Live TT. When powering down, I turn volume down all the way, and out of an abundance of caution, switch the input from phono to cd (nothing is hooked up to the cd input) then power off my phono stage, and then power off my amp. My TT stays on all time. When powering up, I switch on amp first, then phono stage. IS THIS CORRECT? DOES IT MATTER???

Thanks for your input and HAPPY NEW YEAR!

My owners manual says to turn on the sources on first, then the amp. To power down: amp first, then sources.

Follow you owner's manual advice. You can probably avoid the turn-on thump problems doing as Lupinthe3rd does and muting or turning the volume all the way down on the integrated amp, but you do risk a disturbing sound if you forget to do that, and some mute circuits don't entirely cut off signals, depending on the design.

It isn't that I don't "believe" you. With the volume turned all the way down, the claimed issue is nonexistent. Why would I want to do it with volume all the way up?

Tbromgard.. Your manual is correct.

The reason you turn on the amps last is to avoid amplifying any turn on transients from source or upstream components. Yes, some of them emit some pretty intense transients, including my Nagra PLL
