Hi, I'm a noob and really need your help. I'm looking to build a cinema and hifi system with used kit around a new Oppo BDP105 Darbee Edition and two B&W CDM 1st and a CDM CSE centre speaker. Could you advise on a second hand cinema amp powerful enough to match and run the speakers and give musicality too. I'm looking to feed all audio through the Oppo DACs but I'm at a loss where to start. Please help.
