If you are prepared to import then get se846 from Japan. I picked mine up on Tokyo holiday. Typical UK / EU price hike a joke
This is purely from memory so YMMV, sd3 has more bass quantity within inear presentation but se846 kills it for control, extension and impact. Another level in sound and no lacking bass quantity
Thanks for the advice but I've already taken a shot at the fa 4e's!and as Kurdt said, the se846 does seem like a good package but at almost 1000 pounds compared to 300 for the Fischer, the reviews for each really don't seem 3 times the difference!
