I am looking for a good alternative to the beyerdynamic T70p. I liked the resolution of the T70p a lot. The bass was a bit weak but I could have lived with that. The reason, however, why I have sent the T70p back was that it produced a distortion with some songs like I was standing in a can. With classical music this effect was not so strong but with certain pop songs in which the vocals had a slight reverberation the t70p distorted this effect in a very unpleasant way. E.g. the song from "Come to sin" from Bananafishbones sounds completely artificial with the T70p. Are there any alternatives, i.e. headphones which can be driven without amp and have a high resolution and good soundstage? Price range up to 1000 $.
Thanks in advance
