Shunyata has a new powercord called the Python that would work very well on your levinson 334 it replaced the Viper and some people prefer it to the King cobra V 2 I do not.
I personally love the fat man on amps because they give you so much body and weight with excellent transparency.
The best powercords for transparency if your main criteria is getting more information would be the Synergistic designer reference Square.
Realize all the powercords have their own sonic signatures - - So it totally depends on what your individual system needs.
Also mixing different brands of powercords is usually superior to running all one brand.
