Hi Kevziek; Prior to making a choice, I auditioned 7 power cords in my system, to include the Syn. Res. Master Coupler and Sidewinder. I had the Master Coupler and Sidewinder in 20 amp as my McCormack DNA-2DX has a 20 amp input plug. Of the 7 cords auditioned, the Master Coupler was the most neutral with excellent bass and good soundstaging. Others auditioned included an Electra-glide, ESP, Orchard Bay, Audio Industries, and some I don't remember, but later I also tried a Voodoo Mana and a Shunyata Viper 2-- both more colored than the SR-MCs.
Now, over a year later, I have Syn. Res. Master Couplers on all components, and recently they provided a worthwhile up-grade on my Vandersteen 5 speakers (for the speakers sub-woofer amps). I also now have a 14 ft. Master Coupler on my DNA2 Rev. A amp-- I needed this long length to reach dedicated outlets. I also use Syn. Res. ICs (active shielded), and spkr. cables. But as others above have stated, it's really a matter of personal preference.
The Cable Co. will lend wires to try, but there is a rental charge that is then applied toward the purchase price from them, and of course you have to buy "new". Good Luck, and Cheers. Craig.
