If someone could answer a question for me I love vinyl & have been collecting for a few years now have a good turntable. I have been using an old decent amp for years a kenwood model but the speakers keep cutting off and crackling. I have a reciever in mind to replace it being a harman Kardon avr 1500 it has no phono input but was going to buy a decent preamp will that work and work well. Or should I buy a old amp with the phono input or should I get a newish one with the phono input. I want the best sound possible can someone help me?
