Diva Fans, I recently received my 4.1, C3, and 2.1s. They sounded great out of the box and are sounding better everyday. I am driving them with the Onkyo 600. There have been a lot of messages going around saying the Onkyo is underpowered. While I am not completely convinced it's underpowered, it does make me nervous considering my substantial investment in these great looking and sounding speakers. Therefore, I am considering exchanging it for a higher end model, but I am not sure what. So now for the poll, 1. I would like to know what Divas you own 2. What you use to power them 3. Are you satisfied with your receiver or are you considering upgrading in the near future, if so why, and what models are you considering. Thanks so much for everyones input!
