argyro, please look at my other posts. to me, sunrays=hype.
i was a audiophile for many years. iheard/had good speakers, and not so good.heard the sunrays in the last 3 munich shows. i go every year. also heard contriva diacera.
better speaker then sunrays. more balanced.
the sunrays is not so well designed but nice finish.the sound is not natural, and the bass is slow and fat.many designers like the ceramic drivers. cheap, and easy to put in the cabinet.also measures are good. but sounds bad.
it is hard to say"refernce" when people sell them, and they don't sell.now even kharma move away from ceramic.now kharma makes good/great speakers! i also like new big sonus fabor,gamuts7,magico q5, and focal em line.
