Energy RC-10 or Monitor Audio RS1 for Virtue 2 am?

Thanks guys for your inputs/recommendations. So, what would give me better sound quality: a better power cord (like the one you have suggested) or the 30v/130W power supply upgrade that Virtue Audio offers for $150? If there any difference between these updates, how much?
Which speaker cables and interconnects are you guys using with this amp and the RS6?
Thanks a lot in advance!

BTW, I finally bought the RS1. They will be arriving in about a week. I can't wait!
Cheers

The power cord was a huge upgrade. I couldn't imagine the $150 power supply doing as much as the cord I told you about on ebay. $12 plus shipping and it was VERY substantual. Try the power chord before anything else. Hers a link to them.

Or just go to ebay and type in AR power cords and scroll until you find the 2 prong polorized AP803. Make sure you choose the $12 pair. They have several different prices. The shipping was very fast. Hope this helps. I know some might not thing a power cord can make that much differance but the sonic improvement was more than anything else I've done. Trust me on this one. Hope this helps. zman

I use a RS Audio Illume with Silver Bullet terminals. The speaker cable is just 4 runs of oxigen free 14awg wires. Nothing fancy but they sound great. The upgraded $150 power supply has still got a .99 cent power cord and you would still need to upgrade anyway. Try the AR cord and let me know what you think. It brings out the beast killer in the little Virtue TWO. zman
