Even my nokia 2700(classic) have an equalizer...i'm just sad as to the fact that Microsoft/Nokia did not provide this simple control and giving doubtful reason of nokia lumia 520 having minimum hardware and hence does not meet with this feature.
Anyone agree with this?
Yes, the 52x lacks the hardware to support the equalizer.

For equalizer not needed any hardware configuration it is simply a software solution.
That is correct but the CPU still need to be powerful enough to do the processing. Still it is surprising that a dual core 1GHz CPU cannot handle an equalizer.
