When you install the small board of the speedball listen to that for a couple of weeks before installing the large board. I found I liked the sound with the small board and when I installed the large board I felt the charm was gone. I have a C2A and a Mainline so the crack is not used so much , so I think I'll remove the large board at some point in the future. YMMV.
Thank you for the suggestion! I am going to try that.
Plugged the Crack into my Moreplay which has a much better source. The Crack with HD600s sounds super smooth, the bass is surprisingly good, and the highs are sweet - maybe a little rolled off. But that midrange, the midrange is superb. Old, crappy recordings sound the best I’ve ever heard them - Lightnin' Hopkins and old Jerry Jeff Walker never has sounded so good.
I have excellent loud speakers and a good neutral Class D power amp. And with the Crack and HD600s, I don’t hear the resolution, attack, and instrument decay that I hear with my loudspeaker speakers. Does Speedball really help with all that? One more question… with the Crack and HD600s, I don’t hear the 3D, holographic sound stage that I do with my speakers - it sounds like the music is being played in my head. Do you not get sound stage with headphones?
