Mcintosh amp stock pwr cord only 4 ft???

Might only be me but aside from the power cord that came with my Blue Circle BC6000 power conditioner none of the other audio components I have purchased came with anything other than 1M power cords .And, those stayed in the box and were replaced by better power cords. Based upon most of your threads you might be better off research/finding some small "boutique" type shops that can build you custom equipment to your exact specs and save yourself the constant angst.

The shorter the power cord the better. If you need longer, make sure it's super heavy duty with high grade connectors. Good luck.

Get a Pangea with a coupler to the stock cord. Will not affect the SQ of the amp!

A few feet more on pwr cable length dont matter.  Well insulated quality cable good.

crazy to overpay for a pc.  

I've never had a need for more than 3-4ft. If you are going to enter the world of trying various cords, like I've done, try to buy 5ft as those seem to be the most desireable lengths. If you really need 10-12 ft I'd recommend getting some outlets added.
