I used the commercially available inexpensive pigtails. On my speakers they definitely made a sonic difference. Very expended soundstage, but they diffused the focus a bit and souonded overall somewhat phasey. The initial reaction was WOW, but after a while I missed the focus.
So I put them on my amp and this focused things and still enhanced the soundstage. Maybe not as much as on the speaker but to a noticeable extent anyway.
There have been lots of reportings on this type of thing. Many good, some bad, some initially good and then not so good (like me). It is somewhat system dependent. Maybe mine didn;t work on my speakers because my amp is balanced (I've heard others with balanced amps report the same).
In any case it is cheap and worth the trial and error to find out for yourself.
Enjoy,
Bob
