Loving it with my ETHER.

I have always been in the habit of turning the volume down to minimum and then removing my headphones before turning off an amplifier and leaving the volume at minimum and turning on the amplifier before plugging in my headphones as most amps make a loud pop when the phones are left plugged in...

The manual states to unplug the Mjolnir before changing tubes. How many here just turn it off by the switch? Is it necessary to unplug it as well?

My Schiit arrived today. The M2 and a set of balanced ETHERS are burning in with the LISST tubes fed by a Modi 2 Uber via a Wyrd. More impressions to follow. What is the current consensus for best tubes?
