I am listing some of the earphones that I have bought. Koss, Sony, SoundMagic-30. Last one I bought was the Monster Turbine Pro Copper. After I gave it a burnin test for about 40 hours, I tried to listin to some of my favoutite music that I have heard from the other headphones. Since I was always a HiFi enthusiast, I was really amased with the sharp detail, extended dynamic range and the most important the separation of the instruments. I am using tha following:
Cowon S9 32GB + Fiio E5 head amp + the Moster headphones. This combination gives me one of the richest sount experence that I have heard.
My Hifi system consists of Yamaha NS1000(Berillium Tweeter and mid-range) Yamaha M4 and C4 main amp and pre-amp. The Cowon+E5 + the monster headphones exceed the performance of my hifi system.
