V-Ray v.2 or Running Springs Jaco or Audience

I did compare (in my system) RSA Jaco latest and latest Audiece AR6-TS with au24 powrchord. With Jaco, my System sounded more open and more extended. Both did not limit dynamics so. May be audience AR6 can be improved if used with another power cord, but you neeed to utilize that nuetrik connector or you stock with audience cords only.
I sold audience and kept Jaco with no intentions to change it.

I will chime in herre;

The V-Ray is outstanding for HT applications.
The RSA Dimitri should be considered.
The Audience w/ Teflon (T) upgrade will be your best choice.

Power conditioning is so system dependent. Try to find ways to audition if at all possible. Cable Company has a lending library, tho not sure if it includes power conditioners. And Music Direct has a great return policy, as does Tweak Geek. If there is no place local that has these brands.

I agree with Roscoeiii 100%...
