Interfere with the amp...well I replaced the power cord from my halo a23 with a pangea ac-9...the hum from the halo is gone!...another customer had his a21 in for service because of the him...we could not re.create that him at the shop
It was dead quiet...told him my experience..he took it home..got a ac9 power cord
No more hum!... Yes I know ..sooo many nonbelievers in cables/cords..but this took care of the problem....the long dragged out debate over interconnects/cords etc..is no different than the debate over the.all amps sound the same debate!
We have this parasound thread because we know that parasounds are not your average amp...we do believe!.. All I can say is I have no more hum!
And I'm a happy camper!... OK..let the#+$%& fly!
It's quite likely that the improved shielding on the after market cord is what is responsible for your hum being eliminated. As The Factor mentioned, XLRs probably would have done the same. I know this to be true from my own experience with the A-51. I had a noticable hum emanating from all speakers hooked to it until I ran XLRs from the C-2 controller to the amp which solved the problem.
At any rate, congrats on eliminating the hum. It can be a VERY frustrating chore to do so and if all it took was an after market power cord, that's great and an easy fix too.
