We did a usb cable shoot out at my house. The cables used were the $120 Wire World Starlight Red, a $600 WW Platinum, a $600 Light Speed cable and a Pangea. We tried the cables in my system- Pass X250 amp, BAT VK51-se preamp, Luxman DA-06 DAC and Magnepan 1.6 speakers. I also have an Regen and tried the cables with and without the Regen. Bug Head was the music player.
There were marked differences in the sound.
The WW Platinum sounded the best, very detailed, neutral to a slight hint of warmth, full bodied. The Light Speed sounded a bit more detailed but it was painfully bright and irritating much to our surprise because it did not sound that way in my friends system who owns both the Platinum and Light Speed. He uses the Light Speed. Even my friend was shocked at how the LS sounded in my system.
The WW Red was warmer but rolled off. The Pangea was the worst of the lot. It was thin sounding, bright and not very musical.
The kicker here is that when we used the Regen, it was the great equalizer. It made all the cables sound fairly similar except for the Pangea which still sounded thin but less bright.
If I had the money I would get the WW Platinum for my system but the WW Starlight Red sounds great with the Regen.
My advice, get a WW starlight red and a Regen. Or contact- The Cable Company as they let you take several cables on loan to try out and see what fits your system and tastes best.
