Ecka, I own both the XV1s and the Audio Note IO2v. Yes, your description of the sound is spot on. The Audio Note has a much deeper soundstage but not as wide as the XV1s. Comparing the AN and the XV, the XV is definitely a brighter and more detailed sounding cartridge. Both excel in different ways. The XV1s midrange and bass is no match to what the AN can do. Overall, the XV1s is a killer cartridge and so is the AN. Both sound different that's why I have them both hooked up for different presentation.
The XV1s needs 100 hrs to fully settle down but still, your description of both is still correct.
