I used to own a Line 1. Sonic Frontiers tech dept advice: Leave it on standby at all times!
Sonic Frontiers pre Line 2 :off or stand by
My system is:Gyrodec mkV,SME IV,Benz Ruby 2,pre phono Benz PP1,cd EAD 1000 III,pre Sonic Frontiers Line2 SE,amp Sonic Frontiers Power2 loudspeakers Sonus Faber Electa Amator I.For not wear out the pre tubes,when it is no in use is better leave it in stand-by or in off mode.Tell me your experience
