I got this on ebay for $450. It is used with 2 pairs of Dali Helicon 300's and the onwalls. I am driving it with a Simaudio Aurora amp.
ok, sound quality is good and has been a pretty good match for the helicons. Clear and accurate sound. I would recommend this speaker as a center with no problem. For it to keep up with my Helicons surprised me.
I would not say there is anything negative about this speaker.
