At long last, I got Headfonia to publish my review of the inspiring Portaphile Micro headphone amp. While no amp comes sans niggles, Portaphile Micro's few (but hefty) niggles are part of a package that is entirely worthwhile.
“I didn’t expect Micro to positively bump me so well. But it truly is an excellently engineered amp. The 627x has actually become my new bench mark among all-in-one battery-powered headphone amps. But the Micro isn’t far behind. It certainly pairs better with IEMs. It is light, well-made, and compact. It also costs less than the 627x or the Vorzüge, and for the most part, is able to match the performance of either. Yes, battery life is a pain, and yes, you have to ice down your dip stick from time to time, but I think it is worth it.
And if you own Audeze’ awesome LCD-X, it is so damn worth it.”
