Hi Peter,
Yes, I can help! I can build a modified RJ45 to Aux cable to link the PlayMaker into the Aux socket of your 2300 (I would not recommend using an RJ45 to Powerlink cable, as the Datalink and Speaker On pins can interfere with the sound quality when used in the Aux socket).
This will allow you to connect the Pentas to the 2300 with fully-wired mk.2 Powerlink cables (
