I have a new PLX 1602 being delivered to me today. This is my first journey into a power/pre setup and I had a few questions: 1) I will be initially bridging this into a Acme B2 (4 ohms) with 1/4 inputs. Do I need speakon connectors (from the amp) in order to do this? If I don't need to should I anyway in terms of ease of use or sound quality? Thanks.
