Hey there, The BHC Speedball, has a bit bigger stage, is a little smoother, and more 3 dimensional, with better seperation, using my Aeolus. The LP however, is a little stronger in the bass, and the mids are just as good, but a little more forward, and not quite as 3 dimensional. The overall tonality of both amps, is really close with the LP being a bit more neutral, with both sounding hauntingly lifelike in the mids. They both have their strengths, but I prefer the BHC with my Aeolus (300 ohm dynamic), and the LP with my Ori/Blackwood/Alpha Prime (50 ohm planars). However, I would be happy with either one, using my Aeolus. Of course some of this can change a bit, with tube rolling.
