I own the LS25 MKI and the VT100 MKII. The transparent (at least Utra) and the NBS (at least Monitor III) will give the tonal richness while maintaining the extension in the treble and openess in the treble/midrange. You should audition these/every cable in your system before buying. Your system/room preference should determine the "best" for your system.
I have heard both the LS25 MKII and the VT100 MKIII. I prefer the tonal balance of both older versions with NOS 6H23 input tubes. The LS25 MKII and VT100 MKIII do not have the smooth liguidity of the older versions and tend to sound analytical in the Highs (some people characterize this as 'brightness'.) I have no intention of upgrading to the latest version of the LS25 and VT100.
