Hi everybody, I posted a similar thread about this before, but this is a bit of a different question. I have a pair of Campfire Orion's, which have a sensitivity of 114 dB SPL/mW and an impedance of 13.9 ohms. They are mostly used while I am at work or in public transportation. They sound really great right out of my phone, and I am not convinced that I can hear the difference between DACs so the one in my Samsung Galaxy S9 is sufficient. The only problem with them is they noticeably hiss and it bothers me. My question here is should I get an IFI IEMatch to kill the hiss, or should I invest in a portable amp intended for low impedance IEM's such as the Alo audio RX. Is there any audible advantage to using the amp here? I could also go with the IFI nano idsd black label which has the IEMatch output on it. Which would you all choose? Thanks!
