My current systems front stage is a pair of Audio Physic Classic 30s and Classic center which are 4ohm. My surroubds are KEF q150s. My system is biased a bit more to music than HT.\n\nThe system was originally music only and I had a Rega Elicit R powering the mains. Now I have a Marantz 6013 running everything using HT bypass of the Rega to power the mains but that means the 4ohm load of the center is going to the Marantz still while the surrounds are 8ohm.\n\nI’m thinking of replacing the Rega with either a 3 channel or some mono blocks like the Outlaw 2220s. Anything else I should be considering?
