I just finished a shoot out between WW Platinum Silver 7 and Curious “evolved” USB cable; using kapton tape to isolate the USB VCC (N+ to Matrix). Both N+ & Matrix have separate Farad Super3 linear power supplies.
Results - Going from JMaxwell “data only” to Curious “evolved” was a big improvement; tighter low end, better mid-range presence, better sound stage all around. A clear winner.
Results - Going Curious “evolved” to WW PS 7 USB cable - More detail that is smooth, not bright. Deeper sound stage, better micro dynamics. Better musicality, just love that cable in my system. Better tone, just better everything but most of all it was the more detail. So easy to listen to without fatigue. Listening to Jessie Cook and hearing the difference in the low end; fills the music room so naturally. The low end is more musical, better tone, the space is properly (realistically) filled and the bass is so good; excellent extension. The string leading edge has a lot more energy when he is plucking very deliberately starting a flamingo ballad. Better tonal quality with violin, guitar… Jessie Cook “Toy Box” is so good, the bass plucking just went right through me, the resonance and harmonics are so spot on like he was in my music room. Went back and forth and the Curious does not have the bass extension the WW PS 7 has. That WW cable gives me chills with how good the bass sounds. Piano and voices are so realistic. I thought being silver, albeit solid silver, it would sound bright and had zero brightness. This cable was purchased used in good condition and had plenty of hrs burn-in so it sounded great from the jump.
Conclusion - WW PS 7 is better; however, it is not OMG better. If I had a choice, WW PS 7; however, if I had to stay with Curious “evolved” I would be happy too… I had 250hrs on the Curious “evolved” cable.
Next step - So, I got to thinking of testing the SR Sigma USB against the WW PS 7 and getting rid of the Matrix and the support cable and tiny shiny boxes going N+ to DSD. I tried a cheap usb cable from N+ to DSD and it works nice, not as nice as the Matrix; however, it is not an SR Sigma USB cable either. This one I have to think about at $2K for the cable. I will definitely go TCC library to check it out. Going the N+ to DSD I get rid of WW PS 7 USB cable, Matrix, Farad Super3 LPS, SR Delta NR PC, move Nordost V2 HDMI to DMP and lose the HT Magic HDMI cable… definitely worth the audition.
Note - I jumped directly from BII to Matrix and should have tested the N+ directly to DSD (USB) before going with Matrix; a definite mistake in the evolution of my system. In the end I would have probably come to the WW PS 7 usb cable and might have eventually moved to the Matrix. Not sure… just something to think about for those that are looking to move out of the BII… love the Matrix and it sounds amazing, just should have tried the N+ to DSD first since I would be using the same USB cable if I went Matrix… this is a tough call cause the Matrix sounds so good and it has been flawless like my N+… this will be a while, I just want to stop here and enjoy the WW PS 7 usb cable and all that it brings…
