I believe he referred to the A1020 receiver (which is a decent receiver, don't read this wrong) as 'nothing particularly special'. Gene did a few reviews of EMP speakers, (listed as reviews on the EMP site), and specifically stated they were easy loads for the receivers. Most of the impressions series is rated at 6 Ohms.
I've got 4 E55TI(s), which seem an easy load and play loud. I use them as surrounds in a large room. (I like 'em, especially for the money. If you're considering them for a system that has decent subs already, they're very nice, natural, and detailed. They're just not tuned for deep bass.)
