Excellent condition from smoke-fee home. Flat rate USPS shipping to CONUS paid by buyer. I believe these to be an early, original generation of the Pro AC11. Actual plugs and IEC connector provided seem to vary over time.
Harmonic Technology Pro-AC11 CL-3 utilizes the 11-gauge, Single CrystalTM (OCC) 6N purity copper that is at the heart of all Harmonic Technology cable designs that use copper as the conductor.
From Music Direct: Warmth, Detail and Power - Looking for more transparency combined with less coloration and distortion from your electronic components, the Pro AC-11 is your ideal power cord. Every frequency, along with transparency and clarity, is enhanced by this power cord; the inter-note silence is simply dramatic. Since the lack of spurious noise results in a velvety black background, eliminating the “white noise hiss” in the background, distortion is greatly reduced and louder volume levels are possible without fatigue. In addition, low volume levels now have greater clarity and richness, superior to anything you have heard before. If you wish to dramatically upgrade the sound of your system, install Pro AC-11 power cords in each of your electronic components today.
