I have an audio room close to your dimensions - mine is 21ft by 27ft with 9 ftceilings. I am a Maggie fan for the last 30 years. Your system will shine with a set of Maggie 3.7i - to make it perfect add Duke’s Swarm sub woofer System - the subs have their own amp.. This should run you right at $10,000 all in. I am sure you will be very happy with the soundstage and vocals and detail.I do use Krell to push my two sets of Maggies - I have two Listening rooms. Referencing your floor options and dogs - I would use luxury vinyl flooring and then let your wife add multiple oriental rugs - my Wife Happiness factor went up in a big way for both Listening rooms with this tactic.
happy listening!
