I don't think your amplification is up to it for either 803D or 802D. It is proper for your current speakers though. So if you want satisfaction from 803D or 802D, pick your speaker and then start thinking of amplifier upgrade sometime soon.
I mean, Adcom are fine amps, just not for the B&W 800 series.
