I finally did the foam mod after about 7-8 months of owning my pair. I honestly have to say I'm not impressed.
Maybe my expectations were way too high from reading all the comments of how the change was "night and day" and super drastic.
There is a slight difference... I feel that it opens up the soundstage
just a bit more in the way that it is more "air-y" or "space-y"... lol I'm bad at explaining.
But at the same time, I also feel that there was
just a bit of loss in details.
As for bass... maybe it is just ever so slightly punchier? But I really can't tell the difference...
I'll probably end up putting the foam back in soon.. Either way, I still love these headphones
By the way, I'm powering them with a SoundBlaster Audigy SE... which may be the reason why I'm not noticing a huge difference? Or maybe my ears are just untrained.
I'm planning to get a better DAC, and possibly an amp later this year.. any suggestions? Been looking at the Fiio E10
