Among three you mentioned - BAT is the best and by far!!!. No question about it. Even better amps and twice cheaper ones are Spectron Musician III SE monoblocks. Their only problem is price so people who buys Halcro at their astronomical prices will never even try them.

P.S. I do not count LAMM mentioned here simply because they have very different power output - otherwise, its the heaven!
