This system is by far the hottest sounding system that I have heard in my over 20 years of experience! There is only one system, which sounds a little better, the AT-OC9. No common digital medium can achieve such dynamics and the finest heights. Even if you record this with a high-quality sound card in a PC, it sounds more dynamic and natural than any CDDA. However, the prerequisite is a high-quality medium, high-quality mixed music on vinyl, without waves and scratches. And even if it is techno (WestBam crash course), the system and medium brings a touch of naturalness to synthetic music.
