I currently have a turntable set up which is a Rega RP1 playing through a set of Aktimate Blue speakers via a rega pre amp. I don't have an amplifier as the speakers don't require it - they have built in amp, I believe. I'm looking to get a cheap CD player separate (looking at Cambridge Audio cd32-36 but open to suggestions). If I set this up through the pre amp and into the speakers would it work? Or do I need an amplifier?
