Eduardo Niebla chooses Dada's 405 revision
The packing was very secure, well done!
The sound now is much more open and extended; bass to trebles through the whole spectrum are very clear and rich. A very wonderful sound. I'm very very happy . I now can hear very clear my mixing and recording work in much more detail.
Thank you very much for all you wonderful and professional work - I have no hesitation in highly recommending your upgrade services and give you 10/10.
Best wishes to you all (I'm definitely a happy customer)."
