I ask, because I need a new power amp for my 11R. Im currently running it through an old Crown I borrowed, and I think it sounds pretty awesome. I was looking at the new crown drivecore series. The features and power at that price point looks nice. I tried a rocktron velocity 300 because of all the praise Ive heard on how it rocks with modelers. But, the thing died within the first 5 minutes. That doesnt inspire confidence. So, Im thinking Crown has an excellent reputation for reliability. I cant afford to go tube right now.
