After one night of listening various music I can say that the star8 cable is really something special. Like all really good silver cable (Kondo for example), that has this inner light.
No, there will be no more bass (although no less and resolution is also maybe higher down there) and it really has more information in the treble region compared to the stock copper cable.
But it is actually just superficial and doesn't really matter. The point is for me this "inner light". Everything is butter smooth, still not boring, just natural and on top of that, there is some plus "this sound is a real sound" feeling. The human voice, the instruments, everything becomes an other inner layer of illumination. One could maybe say resultion is higher, but to my ears is somehow not just that simple. It is what good silver cable makes. An addictive quality of thruth and artistic, creative meaning within the sound.
Simply said, if you already bought a VM1a and an SR1b...I think it is almost a must have to complete the system.
For other combination of gears, the CA...I don't know, somebody has to try it out.
Catch 1: silver cable is really transparent (as the whole Raal System). Crap in, crap out. Your system hast to up for it I think.
Catch 2: there are big-big differences in silver cables. I had a few, and 8 times of 10 they amp up the resolution in the high, add some shimmer (which at first seems nice), but thus screw up the tonal balance. This "inner light" thing is also missing. I was relieved that the Star8 is not this.
