Solid state amp for Stratus Gold i

Currently using B&K components AV5000 II. Need more power specially now that moved to larger room. System doubles as HT but I give priority to two channel. Budget is $700-$1000.
Rest of system is Source Panasonic DMP-BD-60 Blu-ray, Marantz AV-550 Pre. Have dedicated lines and grounding. Tweaks specially vibration aplenty and some acoustic treatment as well. Thanks for your valuable comments and suggestions.
