EVERYTHING is stressful for the certain piece of equipment more or less...turning it on and off and leaving it on all times...but...devices will work more stable/less neurotic if leaved on all the time...hell...thats what they are build for...you guyz sometimes talking like the equipment will wear off in a 2 weeks if leaved on...most of folks out here dont have 300 bucks receivers but serious and expensive pieces that must work by the specs for at least 15-20 years, especially newer designs with better parts today available...in that time most will change amps 6 times...so dont get what is to worry about...i leave my SS A/B class amp turned all the time, also SS phono and SS d/a...if i had SS class A or anything of the tubes i would turn them off for more practical reasons...
