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

I think you would like the Monitor Audio over the Energy RC-10 with the Virtue 2. I have heard both speakers, as well as the Virtue 2 pushing some Monitor Audio RS-6 floorstanders, and they made an amazing sounding match for a budget price. The RC-10 is not as defined or lively as the RS-1, and the Virtue is slightly relaxed sounding. If you can spring the extra money for the RS-6, you should be even happier with them on The Virtue.

Zman is right, the stock two conductor cord on the basic power supply for that amp is a bottleneck to the current going to it and should be upgraded to something of higher gauge and quality. I would imagine this would be a smart thing to do if you don't intend to upgrade to the more expensive optional power supply or the battery power supply.
