I'm terrible at describing what I'm hearing, but I was doing a comparison of Black Amp, Jot 2 and BHA-1 the other day and here are some of the notes I took. Fair warning, I don't know how to listen critically. I'm purely into headphones for enjoyment. "Black Amp Neutral to maybe a touch leaner than neutral (or at least not as beefy as BHA-1), spacious, liquid, great instrument separation, effortless, Soundstage much better than Jot2, Better than BHA-1 but BHA-1 is closer to Black Amp, Unfazed by complex passages Sounds more like a tube amp than a solid state. Better than normal-people tube amps in clarity and resolution." If I were in the market for an expensive solid state, I'd probably pick this one up because it's really good! But I'm really more into tubes and the price on this is almost an EC big boy tube amp so I'd buy one of those instead. Plus I tend to buy used because I'm a cheap bastard and the Black Amp doesn't exist on the used market.
