Hey, I can't make up my mind which one to get. I've demoed both (at different stores) and really liked the clarity in both. I did like the diamonds a little bit better because of there superior power handling. The only catch is that I will be ordering off of the internet. I was going to either buy the diamonds off of ebay or the CDTs off of woofersetc.com who is a authorized retailer of CDT. Now i've heard of reseller horror stories and think it may best be avoided by ordering from woofersetc? Your input is appreciated.
