I didn't find that much similarity between the 007A and the 404. The upper range peak in the 007A was higher up than the 404, I estimated about 8kHz for the 007A based on the amount of tape hiss I was hearing. The 404 had a deeper bass extension. However with Spritzer's spring mod in place the deep bass seemed pretty equal in the 2 phones and the other lower frequency regions of the 007A seemed more prominent, making the upper frequency peak less prominent. The spring-modded 007A had a sonic signature more like my Sigma/404 but with more deep bass. The 007A has that and better imaging and detail. However, the Sigma/404 has a more open sound due to the forward placing of the drivers.

I really don't like that sort of sound and it was disappointing to say the least to have it transplanted into the O2. |
