I'm buying a new receiver and sort of have it narrowed down to 2; the Pioneer Elite VSX-35TX or the H/K AVR 310. I have 2 concerns with the H/K, the first being THX EX and the fact that H/K doesn't do it and the second being its rated power output. The H/K is rated at only 50x5 but, and here's the part I'm unclear on, it is high current output. Could someone please explain the difference between high current and not so high current output as it applies to audio? I guess my big question is, between the two, which would you buy?
