I've owned a pair of Sony MDR-V6 headphones for many years now and they are great for the type of music I listen to - mainly vocal, with acoustic + electric guitar, but also some latin pop like Marc Anthony, along with stuff like Sting, Chris Rea, George Michael, Eva Cassidy, etc. The thing I get with the V6s is great clarity - I can hear everything in the song, from the different guitar plucks + strums, to the raw vocals. Everything comes through as clear as a bell. The V6s also have good bass, and since I am not a basshead and don't listen to metal, heavy rock, hip hop, etc, I'm just looking for natural, powerful bass, with good soundstage and transparency. To give you an idea, my IEMs are Etymotics, because they suit the type of music I listen to well. I also have to say that I've been really impressed with the V6s, although since they are so old I'm sure I can get an upgrade with some of the headphones you guys have.
My budget is about £200 / $350 and I'd be using a headphone amp + DAC. Can anyone recommend a few models that would give me the clarity I'm looking for? Maybe Beyerdynamic or AKG? Would they have any glaring weaknesses?
Any help is much appreciated :)
