Hmm, maybe I'll have to look a pair of EPH-100s to demo then.
Thanks. I only have one pair of MEElec tri-flange tips that I cut off the third tip to, which I use for my UE900s. I will give those a try tomorrow.
What do you think about the 1964 V3s fitting my requirements? Their Portland office is only a three hour drive away, and I could conceivably go down there and demo them.
If you can demo them, I would definitely recommend that. My hunch is that they might be a little too v-shaped for you - they have more mid-bass than the GR07/UE900/DN1000 and the treble is closer to the GR07 in energy (albeit not quite as harsh). It's not as smooth as the UE900.
