Absolutely of course follow the manufacturers recommendations.
I guess Hegel’s approach is their own and no one should argue against that. They don’t offer a standby or low power state so turning off is the one and only option.
Not having owned a Hegel product, I must accept that their amplifier topologies allow for fast warm up, reaching optimal temp’s quite quickly.
Others advocate for maintaining a standby or low voltage state for component stability and longevity. Hegel appear to be in the relatively immediate performance above ultimate lifespan camp and that’s fine.
I still own a fantastic solid-state behemoth pre and power from Roksan the "Platinum series" which has an automatic low power state for both pre and power, if no input signal is detected but drop a stylus on a record or start a CD and it immediately powers to fully on.
This amp I notice, if I powered down fully would take around twenty minutes to warm up from cold and perform optimally and it is clearly an audible phenomenon but I stress this is not "Burn-In" it’s simply component temperature and operating stability being reached.
Have fun with the Hegel, very nice equipment. If I am in the market for a big integrated they would be on my demo list.
