I purchased a pair of diamond 8.1's about 3 months ago. Soon after, I added an Onkyo 501 receiver and a dayton 10" sub. I bought the diamond 8.1s after hearing great things about them on this forum and elsewhere on the internet. Unfortunately, I bought them over the internet without listening to them first. At first I really liked the diamonds. They have a very wide soundstage and are very smooth and clear. After listening to them over the past 3 months however I have come to realize that I prefer a tad bit brighter sound. The diamonds are great for the price, but to my ears they don't sound "forward" enough and at times can get a little too muddy. I don't dislike warm sounding speakers, but the diamonds coupled with my onkyo receiver is just too warm. Anyone have any upgrade suggestions? I'd be willing to spend $300-$500 to upgrade. Ive heard good things about Klipsch Athena Axiom Polk B&W JBL Fluance (although I am skeptical that they are white van speakers) Thanks in advance. Man I love this forum!
