AudioQuest Thunder High Current 15 Amp Power Cable (2.0 Meters)

Forget about paying full price for this cable…but, if your looking to add refinement to your system, this cable is it.We’re talking improved dynamics, wider and deeper sound stage, fuller richer bass, a smoother mid range, and extended high end without being harsh.I powered my Prima Luna integrated amp with this cable and it made my already great sounding system come to life.

There's nothing wrong with paying a lot of money for jewelry, but don't lie about it's magical powers either.Imagine a 2 lane hwy. You have traveled along for many miles without congestion. Suddenly as you exit the hwy, the road opens up to a 4 lane road, it's very luxurious, but it's only 100ft long, and then returns back to a 2 lane road, and then eventually small dirt roads. What would adding the luxury section contribute to traffic flow?

Product description makes the following fradulent claims, each of which is followed by a brief description of why you should not care:1. Provides Uncompressed High CurrentThis is not even a meaningful statement. "Compressed current" is not a thing. A power cable has only one property that matters, resistance. The resistance of a copper cable is proportional to the cross-sectional area of the cable, specified as it's AWG (american wire gauge). Smaller numbers indicate a thicker wire and therefore the ability to carry more current. This cable is 11AWG meaning it is rated to carry 20-30A with insulation rated to 60C. For reference, 10AWG cable is typically used in household wiring for a 30A circuit that would power a large appliance like an electric dryer or electric range. 10AWG, 3-conductor cable (slightly higher current carrying capacity than this one) sells for approximately $1/ft at the big name home improvement stores. At 2m long, the value of the wire used to construct this cable is approxmately $6. Equivalent male NEMA 5-15 and female IEC-320-C13 connectors to the one's on this cable typically go for less than $4 each. So a higher current-capacity cable with compatible connectors could be built for $14. Note that the NEMA 5-15 outlet that this would plug into is only rated for a max 15A circuit, so the extra current carrying capacity is wasted. Despite claims to the contrary, the additional unnecessary current-carrying capacity provides absolutely no benefit to the attached equipment in terms of vague, subjective sound quality or otherwise.2. Reduces DistortionA blanket statement like "reduces distortion" with absolutely no additional context is completely meaningless. Assuming we're talking about an audio amplifier powered by this cable, the distortion of the amplifier is not affected by the power cable. A good amplifier is designed to generate an output signal that is an exact reproduction of the input signal with a larger magnitude. The power cable simply does not factor into this operation at all. If it does, the amplifier itself is flawed.3. Ensures Dynamic PerformanceAnother vacuous statement. What does this even mean? The above-described $14 equivalent cable (or a standard $5 computer cable for that matter) would provide exactly the same power input to an amplifier or any other piece of attached equipment and would therefore have no impact on performance. Since this cable has a NEMA 5-15 connector which are rated for a 15A maximum supply circuit, the most that could be required by connected equipment is 15A at 120V. Any $5 computer cable is sufficient to handle this load. Again, excess capacity provides no additional benefit whatsoever. An underrated cable would generate additional heat at the same operating load and could pose a fire risk. Luckily, electrical code ensures that any standard cable with a NEMA 5-15 connector is capable of handling the 15A that the attached outlet is rated for. A quick google reveals several detailed experiments which have been carried out by electrical engineers demonstrating absolutely no difference in the power delivered by an 'audiophile grade' overpriced cable and a cheap standard computer cord.4. Solid Long-Grain Copper (LGC)More nonsense. Copper is one of the most conductive metals that is affordable and readily available. It does not shrink when it ages and oxidizes so it does not have problems with connections loosening over time. "long-grain" copper is a nonsense term that has nothing to do with it's ability to deliver power.5. Perfect-Surface Copper (PSC)See #4. Nonsense term. Nothing to do with power delivery.TL;DR; An equivalent cable can be built for $14. Both this cable and the $14 equivalent have excess current carrying capability compared to a standard $5 computer power cord. All three (this $1200 cable, the equivalent $14 cable, and the standard $5 computer cord) supply exactly the same power to any piece of compatible equipment. Don't buy this, but a $5 computer cable and spend the remaining $1195 on something of value.

The Thunder is def a unique design. They have a real substantial look and feel to them. I would only recommend using them on a high current application like an amplifier. You also need to consider the sweep when buying these. They are VERY rigid and difficult to bend.

I didn't think this was possible, but Audioquest have done it! This cable is so good, I can now hear whole new instruments on my CD player. Unreal.
