Just got my Aegir Mono's and am very surprised. I like them a lot. Maybe it's just that I got an entire new system that sounds very different then what I'm used to, but the Aegir's in mono with my LS50 high and low passed to a KEF KF92 powered by my DACMagic 200m (awaiting my Gustard R26) sound excellent. The system is in my garage which is about 35 ft by 30 ft and I'm blown away by how much it fills the whole thing with very detailed and lively sound.
Been listening almost exclusively to old CDs on a 10 year old CD player (HK DVD47) which still through coax sounds damn impressive.
