Let me make a few things clear, before I do any more of what I realize some might see as bashing the ASG-1.
This is an incredible IEM for the introductory price. A/Bing, the ASG-1 blows my EPH-100 out of the water in terms of instrument timbre, overall tonal balance/natural-ness of the sound, bass extension, and a million other ways. From memory alone I know I am hearing things with these that I definitely did not hear with my Klipsch X10; the sound is not as lush or forward, but even though the vocals are not as enveloping, I can hear gentle raspiness of vocals and textures in bass that just weren't there in the X10.
This is a really amazing IEM; to be honest I wasn't sure I'd ever hear anything so precise sounding out of a dynamic driver. The more I listen to it, the more I think I will keep it, because it clearly does things that make it without real competition in the current market of universals.
