Did I really say the word "vastly"? I kinda doubt it
Regardless... I would say thus far I slightly prefer the Icarus III with gold filter...but only just slightly. And I still DEFINITELY don't think they warrant a 76 gbp difference...
Thing is, with the gold, undamped filter, the Icarus sounds remarkably similar to the Master, just doing it a bit better, with the main advantage being that you can push the volume a lot higher without causing distortion. I suspect this perk will be lost upon most people who don't pummel their ears into oblivion on a regular basis as I do..
At lower/normal volumes, I still think the Master wins, though.
Take what you will from this updated opinion, and take it with a grain of salt, as always
