Will edit in the coming weeks... Need to let them burn-in (if one believes in such things)...or... rather let my ears get accustomed to them..

Enough said. So much sound for 350 USD it's crazy.

I started looking for a headphone amp, to improve the Sennheiser IE8's, but mostly for the anticipated delivery of my Unique Melody Merlins. After thorough reading it came down to either the Pico Slim, Headstage Arrow 4G, ibasso T5 or the Leckerton Audio UHA-4.   The Pico Slim was a bit too expensive for my taste, the Arrow to be a poor performer sound-wise and the ibasso T5 had a nice price, but after reading several reviews about paint chipping off I was turned off.   It came down to the UHA-4 and I'm soo satisfied. Not even knowing what...
