I am new to including a power amp to my home theater. My questions are: 1) What type of interconnect cables do you recommend? I am not trying to break the bank. I just purchased a used Acurus A150 to power my mains (Wharfedale Modus One Six). They are rated at 150 watts. As you can see these speakers are not total audiophile ones, but are very underrated. I extremely like these. 2) Some say to leave the power on at all times on power amps. Is this recommended? Wouldn't it suck a lot of electricity? Wouldn't the life of the amps decrease by having it on all the time? 3) The Wharfedales are bi-ampable. It is as stated rated at 150 watt. If I am looking to bi-amp each, should I get a 75-100 x 2 power amp? More wattage will probably fry either the drivers or melt the internal wire in due time? 4) I am somewhat embarrassed to ask, but how do I bridge a power amp that has two channels so it becomes one in order to have more power to drive a center? As mentioned, I am a total rookie with power amps. I have always bought integrated amps, but would like to move toward separates. Any knowledge in this world would be appreciated. Thank you.
