My experience might help your decision. My main system is pretty high end and incorporates a pair os REL SX 212 subs. When I bought these 4 years ago, I followed REL's advice and used their power cables. At that time there were other priorities. About a year ago, I finally got around to trying after market power cords. Audio Sensibility Statement is what I use throughout my system for interconnects and speaker cables, so that is what I ordered. The decision is made easier because the company offers a return privilege. Long story short there was a noticeable improvement. So what can you learn from this? First that improvement is definitely possible, and second, perhaps it might be something that should be considered as not a high priority upgrade. I certainly have no regret for having postponed addressing it.
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!
