Good audio doesn’t sit still; there is continual assessment and revision needed to keep relevant and current. While this would be a blindingly obvious statement in the face of devices like streamers – which are subject to a wealth of external changes to the landscape – you might be forgiven for thinking change in the rest of audio is more of a sleepy backwater: ‘more evolution than revolution’ is the pithy phrase. However, products like the Shunyata Delta NR v2 power cord show that in many cases ‘evolution’ is more than enough.
While it’s best not to describe a product by only pointing to its changes, sometimes an exception is useful. The main change between the Delta NR (which we reviewed in Issue 166) and Delta NR v2 is the use of the company’s own VTX‑Ag conductors, trickled down from the company’s top-end Omega QR flagship power cords. The predecessor used VTX hollow-core copper conductors. VTX-Ag has a core conductor of pure silver with an outer concentric conductor of high-purity OFE copper. That’s very much at odds with conventional audio cables, which tend to go with more commonplace silver-plated copper conductors. There have also been some refinements in the CCI noise reduction filters used in the cable design. Otherwise, however, it’s the same beefy black braided power cord terminating in Shunyata’s own CopperCONN connectors and comes served up in a nice black presentation box with some nice ‘case candy’ (including a reprint – from this parish – of an interview with Caelin Gabriel of Shunyata Research). This might seem trivial, but I think this has the right mix of ‘presentation’ rather than ‘gift-wrapping’ and ‘information’ without ‘overload’.
As ever with Shunyata Research cables, there’s none of that faffing around with burn-in or conditioning, thanks to its own KPIP (Kinetic Phase Inversion Process) performed in the factory. So, it’s good to go from the moment you plug it in.
