The Quattro is not exactly a revised Serial. It is a different IEM but one with some clear upgrades on the older Serials. The new Quattro is a bit more in your face, more lively. Treble notes come clean, collected well extended with excellent accurate transient qualities . Jazz folks will love how the new Quattro sounds with Jazz music. The detail aspect of the trebles is so very good. Vocals and instruments sound amazingly real on the Quattro. There is nothing on the sound of the Quattro that sounds flat or unnatural in any way.
Super blended smooth correct timbre playback all day long with every style of music. the Quattro is a watershed product, one the likes have never crossed my desk before. It is amp dependent like crazy, and the Quattro will show you your cable qualities, maybe more than any other IEM can. Normally this would simply mean the Quattro is transparent, and it is yet the Quattro is dependent on not only power but quality of source. But once you find that synergy you’re home carefree with a form of acceptance.
