Hi, Both cable present a very high end sound. They also have their own strong sides and weak.
With pw1960, that cable is very powerful in sound, it feels like its boosting the volume and everything becomes so engaging and active with added slight aggressiveness. Treble is slightly more zingy and slightly bright but smooth enough to consider it very good and pain free. It has an amazing mid forward sound and vocals are very loud and clear, natural. Pw1960 has incredible resolution and clarity, its a monster in that category. Bass is big it has a feel of being very rumbly and deep, has some effect of also a very big massive surrounding bass, it can sometimes be overwhelming and be too much. I had issue with custom fw and bass it cause me fatigue, but once I rolled back to stock 1z firmware and U region it seemed to have cleared and bass is tighter and faster decay now.
Over all Noire + pw1960 its a very massive powerful sound with tremendous mass and weight in bass, very natural and warm tonality. Can be slightly agitated in treble and bass but that depends what music you listen on...
Plussound Gold Plated Silver, this cable is very different and is much more relaxed and smoothered down due to less activeness and boost in sound. The bass is slightly tighter and offer a quick decay but same time a little stretched but quick, this cable I never had fatigue from bass no matter what firmware I rolled. It feels like the treble is a little less sparkly or lets say sharp? Still maintain shimmery effect and feel more easy on the ear.
Vocals are very well refined and elaborated feels also natural and warm with a little hint of thickness.
Over all this cable is very gentle and smooth , very easy to listen it tames down the beastly powerful Tia Fourte Noire to a more polite and easy experience. If you want a well balanced and soulfull experience that can make your soul shine and bliss, I think this is the cable for it.
So I came to a conclusion to keep both cables for now and see what time will tell and which I will chose in the course of time. As both cable bring me the opportunity to have 2 iem signature in a single iem form factor
