I have an 1100 watt (i'm running 850w) power amp. I want to get a preamp too. Should I get a power conditioner as well? I'd really like to avoid one (the price, and i'd need a rack case--too much to carry around seperately) Do I really need one? What about a surge protector? will that work? Can I just plug the pre and power amps into a socket without problems? Thanks!
