The 2m cable currently has free shipping, the other lengths are not free shipping.
I have compared this power cord to a stock power cord, a 14 gauge hospital grade power cord, and a Signal Cable power cord. On my amp, when I swapped out the Signal Cable power cord for this one, I immediately noticed that there was a much greater level of detail.
I then moved the power cord to the preamp in my desktop setup, replacing a 14 gauge hospital power cord, and again I noticed an tremendous increase in the level of detail.
Definitely worth the money IMHO.
