The OCC849 is a looker isn’t she. The copper looked more slightly rose colored, and I like that. Anyhow, there is my take on the four cables. Each has a specific use and personality. That these cables are a sonic value far outweighing their humble asking price. Sure maybe more expensive cables sound better at times, but that was my whole surprise, that this OC849 was ultimately big staged and had very special mids. It had a tightness in the lower midrange and a firmness in the bass, and it was airy yet smooth in the treble. And finally now we meet the OCC849 which goes to another level adding more meat to the OC849 sound. SO see what we learned today is that each cable is different and holds special properties for those who own them. showcasing specific tonal properties in union with specific IEMs.
