The other day I was thinking about what Mark Coles (Sablon Audio) had told me about how a quality AC power cord noticeably improved the sound of a turntable.

Improving a system’s sound by using a high-performance AC power cord on the turntable wasn’t an intuitive hot-rod mod for me, and I sort of wondered if I added a high-performance power cord if I would even be able to hear an audible difference, given it was just providing AC to the turntable motor.

It was a bit of a moot point for me anyways, because I really didn’t have enough room behind my turntable to fit a jumbo-sized high-performance power cord.

The Acoustic Revive RAS-14 TripleC NCF Power Conditioner.

Then I got to thinking about the Acoustic Revive RAS-14-TripleC NCF Power Stabilizer that I reviewed back in Positive Feedback Issue 91.

The RAS-14 TripleC NCF AC power conditioner is an interesting device, as it looks a bit like a short high-performance power cord, but it is really a hybrid device that melds the performance concepts of the Acoustic Revive RTP Absolute NCF power distributors, which use a combination of vibrational dissipation and passive AC filtration that is achieved through clever applications of materials science, and the Power Reference TripleC NCF AC power cables, which are ultra-performance AC power cables.

Unlike a jumbo-sized high-performance AC power cord, while ogling the space behind my turntables I realized the RAS-14 TripleC NCF AC power conditioner was small enough to fit.

Also, after I reviewed the RAS-14 TripleC NCF AC power conditioner Ken Ishiguro told me I should try it with a generic power cord, he thought I’d be impressed with how it could transform a generic power cord into a high-performance power cord, like the one that came with my Artisan Fidelity TD-124 Statement turntable (above).

Trying the Acoustic Revive RAS-14 TripleC NCF AC power conditioner seemed like the perfect opportunity to put both Mark Coles and Ken Ishiguro’s suggestions to the test!

Then I added the Acoustic Revive RAS-14 TripleC NCF AC power conditioner to the generic power cord of the Thorens and gave it another listen.

Well, it turns out that both Mark and Ken were exactly right, as adding the Acoustic Revive RAS-14 TripleC NCF AC power conditioner yielded an easily audible difference.

Overall, it’s like a veil was removed from the music of Solitary Man. There’s more clarity and apparent detail, more of a sense of space, better dynamics, and Johnny Cash’s voice sounds more present and “real” in the room.

Timbral textures are more apparent, and there’s more musically meaningful nuance in timbre, tone color, dynamics, melodies, and interestingly, the music even sounds a little louder.

I was impressed enough with the result that I grabbed my previous version of the RAS-14 and putt it on my Garrard, which you can see in the photo above, but it’s a little blurry.

I’ll cut to the chase and tell you the result was much the same on the Garrard, with everything improving musically & sonically, in the same sort of way a high-performance power cord does for a preamplifier or amplifier.

If you want to read more about the Acoustic Revive RAS-14 TripleC NCF AC power conditioner, you can read my article in Positive Feedback Issue 91.

I’m rather impressed how well the RAS-14’s worked to improve overall sonics & musicality of my turntables, it was much more than what I was expecting!

As always, thanks for stopping by, and may the tone be with you!

  1. Jeff,

    Since the power conditioner is only supplies the motor and is in no way connected to the cartridge, I was surprised by your results.
    Any theories on how this impacted the audio signal?

    I really enjoy your posts and website.

    Thank you

    • Hi Chris,

      I’m not really sure I completely understand what’s happening between the RAS-14 and the turntable motor, so I can only speculate.

      My best guess at an analogy is from my day job at a national laboratory. Some years ago we built a specialized “quiet” research facility designed to eliminate or reduce to a minimum the physical vibration, acoustic noise, and electromagnetic interference that degraded the resolution of our ultra-sensitive collection of microscopy and scanning instrumentation, which ended up yielding a dramatic improvement in signal-to-noise, and improved the resolution of their images dramatically.

      Even the manufactures’ of the instruments were surprised how much it improved the performance of their instruments. Now these sorts of exotic “quiet” facilities are becoming more common place in research because of the recognized benefits of a “quiet” environment in terns of vibration, acoustic noise, EFI/RFI, and the improvement it yields to imaging research instrumentation.

      If you take a look at the tip of an atomic force microscope (AFM) what does it look like? It looks a lot like the stylus and cantilever of a phonograph cartridge.

      We found that SEM, STM, AFM, DTEM, etc., all performed much better in a very “quiet” environment with everything decoupled from mechanical vibration, electrical noise, RFI/EMI, etc., and the resolution of the images improved significantly.

      I suspect, that in a much more simplified fashion, the same sort of thing is happening with the RAS-14 and the turntable motor. Vibration is being reduced, the quality of the AC is improved, which allows the stylus to experience a quieter environment, and thus providing a better signal with greater resolution.

      That’s my guess.

      The effect is easy enough to hear though, so if you’ve got a high-performance AC cord / power conditioner to spare, give it a try on your turntable and see what you hear.

      Kind regards,


      • Jeff,

        Thanks for the detailed explanation.
        You have Identified a number of variables that I never considered.
        I may just have to try it.

        Thanks again
