I've had a different results with tape. The good things about Pro HD are the soundstage and clarity, and both suffer a lot when you do the tape mod, while bass gets distorted if you push the volume. EQ without mod is a lot more effective, a very small boost to lows, slight reduction to highs, and a nice boost from 250Hz to 1kHz... this seems to give them fun and clear, more balanced sound. Now, because you lift up mids, sometimes you may notice distortion out of nowhere, yet it is not in the lows nor highs, it just goes to show that that second DD should've been BA. Also, not everyone is for eq...In the end, they sound good for the price, but have more flaws than I'd like.
