I’m now using a Zen Wave PSR-14 power cable on my Allnic L4000 preamp to great effect.
The noise floor of this cable is absolutely off-chart low. My PS Audio P10 Power Plant reads a vanishingly low .2% THD+N at the output, so you wouldn’t think much could go wrong in the last five feet of cable. You’d be wrong. Music is now set against the blackest background I’ve ever heard from my system.
My speakers are single driver DIY affairs using Tang Band 1772 drivers, and I’d just resigned myself to a certain amount of tizziness. It’s a whizzer cone, right? To my amazement, the PSR-14 on the preamp resolved a majority of those artifacts. Many cables clean things up by sanding down harmonic textures, but so the PSR-14. Tone and texture are still there in spades as you would expect from paper cone drivers.
Down low, there is some welcome weight to the mid bass. It never feels bloated or ill defined, though. There’s no reason to worry that a 14 AWG cable isn’t delivering enough current to make some first class bass. You will definitely be able to locate the rebel bass!
The PSR-14 was exactly what my preamp needed to perform at its best. Having a ladder DAC with tube output (Aqua LaScala Optologic), a triode preamp (Allnic L4000), and paper cone speakers (Tang Band 1772), I had tone and texture to burn. I went right for the PSR-14. Others with metal or ceramic drivers and solid state front ends may want to consider auditioning the PCR-14. There’s surely something in the Zenwave stable to match your sonic priorities.
Hats off to Dave for creating a world class power cable. A whole family of them, in fact. I’m definitely eager to start auditioning his DSR and D4 interconnects!
