My third set of PS500e's showed up today and look very nice indeed! The lettering on the cups is much better, the headband is symmetrical and the drivers are . Its nice to finally have a great looking and great sounding headphone.
Plugged my ibasso dx50 into my 3 channel cmoy which uses theti lm4562 opamp and played Rage Against The Machine's 'Bulls On Parade' and maaaaaaaaannnnnnn when those opening guitars riffs came through the hair stood up on the back of my neck and i got goosebumps all over. I'd forgotten the ability of these cans to convey that raw energy and make the sound literally leap out of the drivers and attack your ear drums. The low end is simply marvelous for drums and bass guitars and its ability to reproduce stringed instruments is stunning.
Great, so glad you are enjoying them so much so quickly. Having owned the PS500 and now PS500e be aware that these more than most Grados really benefit from break in time. With both of mine they really started to show their stuff at 50 hours and at 100 hours had arrived. They will improve throughout the whole spectrum, the best is yet to come.
Congrats and enjoy, I also find them a real favorite among the Grados and are quite the value (a typical Grado trait and tradition).
