It's all the fault of the Americans. Idle curiosity and general cheapness (mine and the Koss's ((is Koss's even a word????))) led me to buy a pair of Koss KSC75. At first I thought the fanbois were just fanbois and the earphones were a bit ess aich one tee because I used them with low power output personal players and USB sound card. Finally I unpacked from long term storage a Yamaha receiver, connected my PC to it via TOSLINK, and discovered my music collection again. For the last few days I've only slept about three hours per night because I am intoxicated with music (OK on Tuesday it was music and Chilean Merlot).
edit: as this is a Clip+ thread I have to say right away don't bother with Koss KSC75 or KSC35 or Porta Pro with your Clip+. They are 60 ohm 'phones with sensitivity of 101 dB SPL/1mW. The Clip+ cannot drive them. There is some sound but it is anaemic and disappointing. My iRiver H140 and H340 are a bit better but not ideal. These things come alive on an amplifier and are so enjoyable it's ridiculous. I spent 10 years using Sennheiser HD 500, then Sony ZX700. The Koss KSC75 are so much better that it defies belief.
@Koss fanbois: you were right all along. I am a kosser.
