output impedance to high for iem's??

Hello, took advantage of some of the deals going on lately. Snagged the tf10's from Amazon and the um3xrc from earphonesolutions. My home rig I am using a gdaudio compass to power my D7000's. The compass has an output impedance of 10 I believe. Will I have any issues using the compass to power these iem's at home?

Thanks!

Mate, IEMs don't even need an amp.

I understand that. But my whole digital library of FLAC is on my PC connected to the compass. So if I wanted to use them at home, not on the go, this would be the easiest for me.

for iems, it's better if the output is lower than 1, the lower the better.

I think sensitive multi BA IEMs will have issues with an output impedance of greater than 1.

 

I'm not sure how great of an affect it will have as I've always only used sources with < 1 output impedance, but I would probably find another source for those IEMs - your ipod classic unamped will do fine (I'm assuming it has an output impedance of < 1, but I'm not actually sure).

Ok I think was incorrect with the output impedance of the Compass. I believe it is 1.5. I think I should be fine as my Denon D7000's have a very low impedance of 25, the UM3X is 56, and TF10 is 32. So it may not be completely optimal at 1.5 I think I should be fine(hoping). My main concern was blowing a driver or worse on my new IEM's.

 

Any suggestions of a cheap amp/dac that has a output impedance of 1 or less? Must have optical though. Obviously I would rather just use the Compass, but if I have to I can look into something else.
