I bought my eq7 from sale forum here so dont think I could do anything now but I'll be interested to hear how the DBA sounds
How the cable got ripped off or what happened? do you have a picture?
P.S. By any chance did you order your e-Q7 from Dimitri from Musica Acoustics.com?
According to Dimitri, I got full warranty service support in case of failure of my e-q5 for period of one year since date of purchase, free of charge..
Even if you did not, advice you to contact and inquiry...
