I had to reduce 3k and 5k to be comfortable. It was a shame to let them go as they were really good at what they were doing. Not warm enough for me even though it would dig deep (for a BA setup) if there was a lot of bass on the track. I don't really want to use EQ just to get a sound that I like. Ideally (perhaps futilely?) I'd like the IEM to do that by itself.
Hopefully if the UK Canjam goes ahead I would like to try a 64audio U12 to see if that's where I'm heading.
Where in the UK are you based? If you're close to Devon you can take a listen to mine... if not, I believe Selfridges have a demo pair in London?
