Hey guys! First off, i want to thank you all. This forum has so much information. All of the guides and helpful members here really make it easier for a noob like me to pick the right IEM for our listening needs. Now. I just purchased the Westone 2's. From what i have read, they are a great headphones um-amped. But what about when under the power on an amp? Say.. The PA2v2? Would the sound quality to an un-trained ear be improved much? If the amp isnt necessary, are there any other things i can do to improve sound? Could i possibly use bottom port of my iphone 4 for the headphone jack? I have seen quite a few people do that. Thanks!
