they are QRS Jupiters, made by a small team of guys in town just outside Göteborg in Sweden. They work in partnership with the Advantage and Bladelius designers.
Not sure of the price, but they beat the MÃ¥rten Design Coltrane (£30k) easily with the same amps and player.
Other top speakers are these, Goldmunds, very nice with Jazz :MILD:
