Thanks Rgopalan,
Infact I am looking for an upgrade from 683 and I see that 804D comes with Diamond tweeters I am interested.
I just want to know if the old version available since it might cost me less than current one, I am not sure whats the current model price as well. You can suggest me which would be a better option. Will it be a big difference from 683. I am loving my 683 but will this monster perform better than that?
Regards,
San
