Well I sold the emotiva before I received the Bat so I cannot make an A/B comparison, but I owned the emotiva long enough to know the sound quite well. The main things that jumped out at me. The Bat is a little darker sounding, the UPA-2 was not bright but was not quite as dark. The Bat definitely takes an hour to warm up, until warm the sound is VERY dark almost cutoff. The Emotiva sounded pretty much the same from the time you turned it on. I cannot tell if either are more detailed, but the Bat sounds more realistic, which is the goal. While my system is sounding its best and I have no plans to sell anything I have grown in my respect to the quality products emotiva is putting out. I truly believe for the $4500 that an emotiva system with XSP-1, XPA-2, ERC-2, and Magnepan 1.7 would be at least 90% of my system currently costing $18,000 retail value. My old setup was USP-1, ERC-1, UPA-2, and Mag 1.6, I do not currently own any emotiva components but if I even need the cash emotiva WILL be my downgrade system.
