Hey MickeyVee..
Do you know if there's a significant difference in getting the Uber upgrade for your bifrost when using the HD700s?
^^ Yup.. the Birfrost Uber provided more detail while being smoother and had better bass. Definitely worth the money! For me, it took a $1K DAC to beat it.
So, here's what I thought was a quick and interesting observation. I've had a demo unit of an HD 700 for the last 7 days and enjoyed it so much that I grabbed my own on Friday. From the shape the demo unit is in and knowing how many people have used them before me, it's pretty safe to assume there are a significant amount of hours on them. This as opposed to my own personal copy which has a handful of hours on them. Well for the last couple of hours, I started to AB them and I've noticed a difference. My copy has a certain looseness in the treble that doesn't exist in the demo unit. There's also a level of sibilance in my copy that, again, does not exist in the demo unit. The differences are negligible, but I am 100% certain they are there. My assumption is that on mine, with time and more hours, the treble will tighten up and the sibilance will reduce to levels that match the demo unit.
I know what kind of line I'm walking by posting this, but it really wasn't meant to start the futile debate of burn-in. Take the observation how you will.
I still think that earpad softening plays a much bigger part in these treble reductions in the 'burn in' process.
