Although it is possible to have a slight improvement with upgraded power cords on subwoofers its most likely not worth the trouble or expense. Your money is better spent on something else. I speak from experience because I've done the upgrade. In my case I needed much longer power cords for the pair of subwoofers in order to reach the AC outlet.
Are upgraded power cables for subwoofers worth it?
I recently have been filling in all of the holes in my secondary system. Recently picked up a shunyata power conditioner, upgraded speaker cables, and power cable for my amplifier.
My question is, is it worth running higher end audiophile power cables with subwoofers, considering distortion is not as apparent to the human ear in the sub bass range? I use a high end receiver for my DAC in this system with a normal power cable as well. Would I get better performance increase from upgrading sub cables or my DAC(receiver w pre outs) power cable?
Any specific suggestions for sub power cables, or DAC power cables that are inexpensive (sub 200 or even $100)
Thanks for your time!
