Outlaw RR2150 Receiver Power Cord?



I was reading through the manual and noticed that it says NOT to use any other power cord except the one provided with amp. Most, if not all companies have encouraged replacing their stock cords. Why would Outlaw Audio discourage owners from using an aftermarket power cord? I have been using an aftermarket power cord for a few months now with this receiver with no issues it has actually improved the sound in my setup.

Any other owners using an aftermarket power cord with this receiver?

Though many auto manufacturers do offer different tire options at different price points.
The manufacturers say they are often in a tough spot, wanting to include a good cord, but knowing many/most owners will not use it.
I think their solution will be to not include a cord at all. At least on the ultra high-end stuff. They cannot say one PC is better than another for their product, that would cause an uproar like never seen before.
I totally agree Rok2id. And out of curiosity I looked, and the basic BMW 7 series sedan offers tire option upgrades beginning at $1300.00
I put a $99 Venom 3 cord by Shunyata Research on my Dad's Outlaw 2150. He loves it so much, he bought another one for his NAD 326BEE. These cords are UL certified, so no worries. They beat or equal cords costing 5 times the price. (see Stereophile's review..Budget product of the year.)
