Summary Very solid headphone , even if it feels plastiky, as many of reviewers mentionned.  I use it on my PC to perform remixes and audio remastering using verious tools such as AUdacity, Acid and MixMeister.   Tried on my home theater (marantz SR5001) and I am not impressed with bass impact. This bings me to a question : What amplifier shoud I consider in order to get stronger bass ?
