I will soon be receiving a Musical Fidelity A5 integrated amp. The remote does not have a power on/off function. I've become very used to turning my equipment on and off with a remote. I'm sure I can get used to turning it on and off manually however, I've heard different opinions on whether it's better to leave an amplifier on all the time or to keep it in standby when not in use. Would it be alright to leave the A5 on all the time?
