Hi guys,
I got a couple of question about GO IEM 100 whose answere I haven't found in this enormous thread and in the net so I'll ask here:
- does both the jack avayable have 0.47 ohm impedance?
- do they both output max 100mW power?
- can they be used simultaneously? If yes, when used simultaneusly do they both output 100mW power?
- does GO IEM became as hot as GO 450-1000? Last time I checked some GO 450-1000 reached more than 60° under normal usage...
- besides IEM is GO 100 suitable for low impedance & sensible cans (like sennheiser momentum)?
- can you tell me please what is the maximum power draw of the GO IEM? Is it per chance 100mW as the name implies? I ask this because is important in a mobile perspective, used with OTG cable on smartphone, where che maximum current suppliable is 200mW.
Thank you in advance for your patience answering me,

Here are the best answers I can give as an owner of the GO100 IEM:
No, both output jacks are not .47 Ohm, one is, and the other is 47 Ohm for use with higher impedance 'phones.
What they output as maximum power depends on the impedance they are driving.
Yes both jacks can be used simultaneously, however the 100mW total output power is split/shared in that scenario.
No the 100 IEM does not get as hot as the 450 or 1000, the 1000 gets the hottest being the highest powered, with the 450 and 100 progressively less hot, though still plenty warm due to running in Class A. How exactly warm is also a function of how loud you are listening, and the impedance you are driving.
Yes the 100 is suitable for other efficient 'phones, it has no problem with the Sennheiser HD558/598 for instance through the 47 Ohm tap. Your mileage may vary depending on what loudness levels you demand.
I don't know what the maximum power draw is, but the 100 does work without the need of a y-split USB cable/external battery, with both the Motorola Nexus 6, and LG G2 for instance.
