The V14D was specifically designed for devices that reside entirely in the digital domain; it's noise filter functionality has been optimized for this, and as such, it was designed for digital streamers, network bridges, Ethernet switches, routers, music servers, etc. It also works a treat on HDTVs and AVRs.
Oh, here's an example for you: I recently had to power my Sonore OpticalModule with one of my original Shunyata Venom 3 power cords because I needed the Venom V14D for the Fidata HFAS1 I was reviewing for
TAS. Once I was done with the review, I put the V14D back onto the Sonore OpticalModule and heard a very clear improvement in clarity, tonality, and reduction in noise.
The Venom V10, and Delta, Alpha, Sigma NRv2, and Omega PC were specifically designed for noise reduction the internal (full-wave bridge rectifier) power supplies for "analog-domain" components themselves, e.g. amps, preamps, phono stages and DACs (this is why the NR filter is at the component IEC receptacle end).
Yes, in theory. However, the biggest problem are the Furman power conditioner themselves. Any fairly subtle sonci differences between the Venom 10 XC and Venom V10 will be masked by the Furmans.
A much better solution is to use a Shunyata Venom PS8 powered by a Venom NRv10.
My suggestion is to rent in the power cables you're interested and listen for yourself. Once you have listened for a bit and have made an informed decision, our fearless leader, MasterLu, will quickly and effectively get you sussed with any products you may decide you want to get.
