I do not have any other resistor with me, I am hoping to order some soon. The cause of the hissing is just the balance armature. I think for the consumer market the bass port is not going to have any purpose.
After inspecting the bass port I noticed that you must have the bass port passed half way between the the fully close and opening marking one. The bass port has a cut in strip that gets wider as the bass port is opened more. The cut starts right when the bass port is pass the halfway of the first section.
I know I read somewhere that cable swapping has an effect I just cannot find where it was, I am thinking of trying to order Fiio westone cable, would westone cables work for ASG-2? As much as I like the stock cable however the memory wire used is just too stiff.
All and all I absolutely love this for certain type of music (modern pop) and dislike it for other one (old 1950 live recording).
It is suitable for large portion of my music hence why I am keeping it as it does pop, modern jazz and chamber music just right. It sometimes have amazing hollow effect which at times can sound artifical but the sense of echo is present nicely in my chamber music. I am on border on how it sounds with piano notes but it is certainly good enough for regular listening.
I did not like how it sounded out of AK120 however once I paired it with O2 the sound improved by a large margin. The dynamic driver really loves the gain switch of the O2. It certainly gives more of a punch when it is used on the high gain.
Yes, Westone cables work with it. I believe Westone also uses recessed jack.
I really can't wait for next week, which is when I'll be sending off my ASG-1s for upgrade.
Really piano sounds fine on ASG-1, I listen to it a lot. The dynamic driver's range works nicely for it. I don't see why the two tweeters would change it, as I assume they are for upper mids and highs. That can only bring the high notes more forward bringing more balance to these phones. Right now the highs being rolled off are the biggest issue with the ASG-1s.
