How does the transparency of the gr07 compare to the similarly priced dual balanced armatures like dba-02 mkii or rockit sounds re-50? I'm considering a replacement just in case my dba-02 (original) breaks down from severe channel imbalance (it's already showing signs of this problem)
Different strengths and weaknesses. Personally I think the DBA-02 is more transparent than the GR07 and even the R-50 but the gap is small. You're better off considering if you'll like the extra bass of the GR07.
