Past IEM: I am looking to replace my REOs due to breakage.They were a little too analytical and weak in the low end for me.
Criteria: 1) Balanced sound, 2) some warmth, 3) solid sound stage and instrument separation; 4) good build quality;
Contenders so far: 1) MEE CC51, 2) Nuforce 700, 3) Beyerdynamics DTX 80, 4) Thinksound Rain
Which of the above would you recommend? Are there any other models that fit my criteria?
