Soooo I've ended up ordering 3 pairs.
- Aurisonics ASG-1 (121db/1mW (Freq not posted) and 32ohm, This is a bit worrying)
- Atrio M5 (Sucks they dont have removable cable) (112db@30hz/1mW and 32 ohm, these should be good)
- UE Super.Fi 5EB (These are hard to find!!, The mix of dynamic and BA looks neat.) (119db/1mW and 21ohms, hopefully these are ok).
I will likely keep all 3 to collect, hopefully I enjoy at least one pair.
