This demonstration of the Rode M5 sounds pretty good.

I've own this RODE M5 kit and found them to be a great price but a bit metallic sounding. I tried them through a variety of tube pre's which helped soften the sound but still wasn't overly happy with the sound. They are a hell of a deal for the price though.

Its interesting how something sounds ok today when I don't have another option to compare against. I put more focus on the overall performance and simply enjoyed to whole video and the group performing. 

I'm a sucker for string quartets.

Enjoy
