Although it was for a captive power cord on a Cary SLA-70Sig tube amp driving a full range speaker with transmission line bass down to upper 20's (perhaps, not as deep as a true sub-woofer), the plugging of the captive power cord into the very highest version of the Mapleshade Records power strip (conditions without the appearance of being a conditioner) allowed the deep bass to become more defined, pitch accurate, and even deeper, by judgement of three pairs of ears (not confined to one head, by the way :>)
Not sure if this is an item with a return option, if you are not similarly rewarded by low bass satisfaction.
I would hesitate to clip short a captive power cord in order to attach the Mapleshade Records Pig Tail power cord option, although it is supposed to work, according to the website. It just seems so irreversible if you don't hear an improvement. By contrast, the power strip helps the sound of all component power cords that I have inserted, without any surgery.
