I received a pair of magnum v4 Goldie's last week courtesy of head Fi member Nick01. I have always loved the grado sound but all the grados I have had in the past have given me treble fatigue leaving me to have to stick with my hd650s. Well I'm happy to report that the v4 magnums not only solve that upper mids harshness problem but are among the smoothest headphones I have ever used. I find their sound perfect with quarter modded hd414 pads and am awaiting a pair of new Ttvj flats which I think may be even better, I had a pair of flats when I had my rs2s but sold them off with the headphones as I had sworn myself off grado for good as I was feeling that it was somewhat of a fatal attraction and my ringing ears would thank me later. What do the v4s do that is so great? The answer is everything. Great balance of sound, perfect mids, smooth highs, punchy and powerful bass - in a word perfection and they only have about 50 hrs on them so far so it can only get even better with another 100 hrs burn in. Now a question for all you ms pro users out there, I have always been fascinated by the ms pro and view it as the one that got away in my headphone journey, now that I have found perfection in the v4 magnums I still would like to know how the ms pros match up. Has anyone heard both and would I be wise to tame the lust for the ms pros and rest assured that the v4 is the smoothest and most balanced grado variant out there or should I hunt down a pair of ms pros in the future and battle them off for ultimate status.
