In Reply to: RE: Krell says only stock cords on their amps? posted by ejlif on September 25, 2014 at 09:46:51
On some older Krells they used IEC C20 inlets. On other higeher power Krell amps, they used heavy gauge captive power cords not only for safety but for a better connection, as do some other high powered amps.
Something to think about when buying an aftermarket cord for some large amps.... Which AC inlet type is used on the Krell Duo 300?
IEC C20 Inlet
More common IEC C14 Inlet

pic, 20A IEC. 15's suck. not enough contact surface in that a large gauge power cord can easily come loose, fall out etc. Physically the 15 is just not good enough. The 20 is.

Good pic showing the IEC C20 inlet.
Yup. ARC also uses IEC C20 on some of their larger products as well.
Contact surface and solid tight connection at the AC inlet is much more important on high power components like large power amps for safety reasons. Poor connections at high current draw will cause heat and the potential for fire.
Many older large Krell amps used large gauge welded captive power cords for this reason, as do some other amps in production today.
Great pics guys. Audioquest, XLO, Kimber and Tara Labs can be used on Krell amps.
Roger roger, I agree. I think in the perfect scenario the 15A can easily handle the electrical load which is often just a few amps but I see far too many after market cords with weight and mass that either fit loose or easily come disconnected or both from the 15 that cannot from the 20.
