My vote would go to Einstein. Einstein is a complete opposite of ASR in terms of design. It's lightweight and looks like one of the Music Fidelity X-cans, in terms of shape and size. But it can go head to head against the ASR, which is a two box design that weighs about 20 times more than the Einstein. Both have different sound characteristics. I had heard them compared side-by-side, and I think it comes down to personal taste. But getting your hands on an Einstein would be a challenge. My friend has the single-ended version and has been waiting for a balanced version for at least 4 or 5 months. The US distributor has been telling him few more weeks every week for the past 3 months.
