Thanks bdp24. But note that the LS7 preamp only provides unbalanced RCA outputs. And using an adapter to put the unbalanced signals into the amp’s XLR inputs would most likely still result in the LS7 seeing a 15K load, as the 30K figure most likely reflects the sum of the impedances of the two legs of each of the balanced inputs.
