Very small room but nice acoustics with fabric and batting behind recessed wall panels. Passes the WAF (wife acceptance factor). Detailed and airy with good soundstaging. I am happy with the sound especially considering my in relative terms, somewhat modest budget. Separate home theater system with Triad speakers behind fabric and Dennon receiver, 2 Polk subs in floor, Sony XBR 85". I never had a dedicated media room before and I am in heaven. Easily my favorite room in the house and just completed it.
I have the McIntosh MC152 too and considering to upgrade the speakers to something in the level of yours, The MC152 has enuogh power to move your speakers properly ?
