Good advice,
I switch my DAW PC off every time when not using it, but my Focusrite Saffire Pro 40 is switched on all the time.
I have used it for more as 10 years as my main audio interface, but since firewire is not
supported by Windows I use it as a converter, headphone amp and preamp via ADAT with an RME Raydat.
The Saffire pro still works good.
I think that it's not a problem to leave an Focusrite audio interface swtched on.
Hee, Amazon is compressing the music the worst in the music world.
I 've never heard more distorted music titles on Amazon than on any other music platform.
