Which amp will cause a larger increase in electric bill?

Threshold SA/4e or Threshold S500 II? How to determine? I cant find idle draw on SA/4e.

Thanks.

If sitting idle (power on), which will cost more, a class A 100 watt (Threshold) vs a 250 watt A/AB (Threshold)? I have both and a few more. I'm not worried about electric bill, just wondering.
