There is really only one Khorus speaker to own if you want to experience the full extent of what this speaker can do: the Khorus X mk II. I've owned no fewer than 7 pair of Talon speakers and until I owned this set with the CMRC crossover, it was a labor of love and persistence, not always rewarded. The crossover provides the magic. The speakers deliver everything you read about in descriptions of high quality, highly musical speakers including excellent bass, a smooth and extended high end, realistic, musical mid-range response, and a life-sized soundstage. Having owned this speaker since 2005, other brands have come and gone and I've spent some time in high end shops and I have yet to come away with the feeling that I need to trade or sell them or attempt an upgrade. The Khorus X mk II is really tough to beat considering what you might pay for a pair on the used speaker market, and especially considering what you'd have to pay for a new pair of high end speakers of similar quality.
