Feel free to tell me about the IEMs you had in mind, I'm always on the lookout for something better.
That said I know a part of what makes an IEM appreciated is how it flatters or sweetens a range of recordings. AFAIK GR07BE doesn't make such compromises. Basically I wanna hear what the engineer heard in the control room. This implies large treated rooms with large speakers that have a coherent, held together and precise sound. I'm a musician and I need to be able to hear into the mix to pick out instrument parts, if I need to. Emphasis on if I need to, truly analytical 'phones can makes ear fatigue kick in rather fast. Fantastic detail resolution a la HD800, is another quality that I will allow take a step back on if my primary requirements are met. These will second as tracking headphones, stage monitors and mix monitors.
I'm thinking about about what cheap IEMs to suggest friends that perform and produce music. The VSD1 and Zero tenore (slightly laid back highs)look like valid choices, what do you think?
