In Reply to: No, I think the KSA-250 draws over 1300 watts posted by AbeCollins on January 22, 2015 at 15:48:03:
"115VAC nom." is long gone. It's now 120VAC nominal per ANSI C84.1 Assuming your utility company adheres to this standard, they are allowed a +/- 5% swing in this 120V number for normal operations, as delivered to your meter lugs; 114-126VAC.
What happens downstream from there is your problem. A utility has no control over interior wiring quality in a customers location.
Per NEC, a branch circuit load in operation for 3 hours or longer is limited to 80% of it's nominal rating. Thus a typical 15A residential branch circuit is limited to 12A continuous.
Krells' power consumption rating of a nice round number (12A) seems a bit convenient and possibly due to the circuit restrictions of the NEC.
Otherwise you are correct. The Krell has an electrical 'mileage rating' along the lines of an Abrams tank.
For a teardown vid of a KSA-250, see:

Not much chance of air circulation inside that chassis, IMO. Especially considering the power consumption rating.
