Since it said in its spec that
" Impedance 182 Ω , Sensitivity 93dB "

Seem like this one required so much power.

Thanks in advance for all the future suggestion

XI audio Broadway?
(It has massive power and is battery powered but not technically very portable)

Yup, not that in the size that to carry in messenget bag or even notebook bag
but thanks for this information

I looked into XI audio amp reviews. Seems like it were good one.

The E1DA 9038s has plenty of power in a very small form factor. Might be worth you considering if you want a dac/amp, rather than just an amp.

I've never heard the C Cu, but the Ray Samuels SR-71A has no problem driving high impedance, low sensitivity stuff, as well as planars. (HD800, Argons). It's not tiny but it's still very portable. Amps in similar power class that I haven't used personally include Plussound Cloud Nine, Headamp Pico Power, Fiio A5. Note that of those I just listed, all but the Fiio A5 run on dual nine volts.

Transportable (but too big to be considered truly portable) options: Obviously the iFi Micro BL is designed to drive any headphones and should have no problem. (I don't have one, though.) I do have a Phatlab Phantasy which is a great (but ginormous) portable tube amp and a good pairing for anything high-impedance. (Unless the IEMs are sensitive to source impedance, which sometimes happens even with IEMs that are rated as high impedance themselves.)

SR-71A is the most interested one. I tried Pico Power with all hope but it still can't put this giant to it best so I think the rest wont be able to drive it to the full potential.

For now, I have Govibe porta tube+ and iFi Micro DSD BL with me. Both can drive this one pretty nice in different sound signature but still it can't produce the enormous presentation when I heard it with some desktop amp which are the reason the I look for some more choice that could have more power than these two.
