ok, this question may sound totally out of left field, but i'm asking because i'm concerned with energy bills.

i know that these digital amps are more efficient. my old tube amp drew 230 watts and i know solid state amps draw even more.

the panasonic xr50 is rated at 135watts of consumption. does it always draw this amount or does it depend on the channels being used and the volume?

i'm asking because i like to leave these things on all day and i'm wondering how bad this is for power consumption.

Tomek,

The power consumption depends on the volume level and number of channels being used (for a HT receiver).  When it is left ON without playing music, it probably draws much less power than the rated value.  

The exception to this are Class A amps.  They are space heaters in idle mode

Check your manual, usually on the page where the manufacturer puts all the specs, is an idle power consumption number.


For example, on my Yamaha RX-V1400, power consumption is listed as 500 watts,  there is another entry for "Standby Power Consumption" which is 0.5 watts.
