need advice with power cable


I have been changing my Straightwire Symphony cables to Morrow audio cables, just got the Morrow MAP3 power cable for my receiver (Arcam avr400).
My question is, I have a Panamax M5100 conditioner should I plug in the power cord from receiver to the Panamax or the wall? Seems some prefer not to use conditioners.
BTW the Morrow cables made a huge and awesome differences in my sound.
thanks for any input

The concensus is pretty clear from all of you "LISTENING" and thats what I will do, I'll try from amp to conditioner and get more cables if needed to experiment.
I want to thank all of you for your valuable input.
Elizabeth,
Plugging it to the conditioner makes the break in faster,
thank you so much I had not thought about that.
Can i replace the stock 15A  power cord with a 20A custom.?

Will this cause any problems to the Arcam AVR400

Thanks
