Hi Gerry,

Sorry, I haven't heard any feedback on the Sony ES and low-impedance loads. Among my colleagues, I don't know of anyone with a Sony receiver. There's a consensus that Sony's ES line has much higher standards than the low-priced stuff, but that's not enough to make judgments about its performance with low-impedance loads.
