Is it advisable to leave your Amp switched on all the time even when not listening to anything!
Save Electricity people.
The amp when ON (or on standby), draws idle power constantly. So if it is not absolutely necessary, it is better to switch off the amp when not in use. Doing so you are saving some valuable energy and avoiding unnecessary exposure of your valuable equipments to power surges and lightening!!.
Many of the modern amps (or AVRs) have a standby power consumption of ~0.1 watts. Which translates to 2.4W per day, which is equivalent to the power consumed by a 36W slim tubelight in 4 mins. Hence, power saving is not that big an issue.
The bigger issue is exposure to voltage fluctations/ spikes, given the Indian conditions. So better keep it switched off.
But in theory, keeping the amp in standby generates some heat, which prevents moisture condensation, especially in coastal areas or in monsoons.
Even if 500 members of this forum leaves their equipment powered on unnescessarily then total 1200W (500x2.4) of energy will be wasted everyday. Even small individual contribution (however small) makeas a great difference.
Every drop makes a difference!
Unless you have some very good power conditioning in place, this is a bad idea. If you do not want to hear sound through the AVR, connect the STB to the TV directly.

I mean this passthrough is a feature that modern day AVRs are offering, so if this is not good for the receiver itself then this would be a bad thing that the manufacturers are selling. I suppose we have to keep the AVR in standby power mode to allow the passthrough (not that I own one but only plan to purchase at this point) and this will not happen if the power is turned off.

Leaving the amp 'ON/IDLE' is different from 'STAND-BY'.
For Eg. my NAD stereo amp consumes 0.5W in 'STAND -BY', 40W in 'IDLE' and 350W during 'ON/RUNNIG'.
This translates to 1 unit consumption for every 1000 hours when the amp left on 'STAND-BY', 1 unit consumption for every 25 hours when the amp is left 'IDLE' and 1 unit consumption 2 hr 45 mins of the amp in 'RUNNING/ON'.
Thanks for the explaination. Do you have any idea if the signal passthrough (for HDMI swiitching only and not the 3D passthrough feature) feature work in standby mode or does it work only in idle / power on mode?

I keep my subwoofer amps on all the time...
Atleast my Denon AVR 1611 does not allow pass thru in standby mode.
Oh sure it does..there is HDMI passthrough in 1611
