-sound style: warm thick british sound, fits my style for listening light vocal jazz
From my quick research (i tested at lunch time and bought same day after work!)
the brand Castle was originally an old British brand with speakers made in england, but was sold to the Chinese company - IAG (same Co. that owns Quad / wharfedale ...etc) a few years ago and disappeared in the market a while. Only recently they relaunch some old + new models....
To be honest i can't find any online reviews or not even user comment from forums.... so i'm kinda brave!! hahah, or stupid.......
