I have compared a variety of cables from all kinds of manufacturers and have learned that only 3 things matter in an interconnect. The first is shielding this is used to stop hiss and hum from getting into your equipment. Any length of wire can become an antenna and cause noise issues. This is solved with what is called a faraday cage. This is the same principle for why you are safer in a car when lightning strikes electricity flows around but not through you. Electricity wants to find the quickest path to ground or the path of least resistance. This is done in a cable by putting a copper braid around the signal conductor so the noise is grounded out before it can reach the center conductor. The next is capacitance, capacitance occurs when you put two pieces of metal next to eachother separated by an insulator. Capacitance is the charge built up and released electrostatically, because this is an out of phase signal (speaker push in it push out or vice versa) that cancels out it will cause high frequency roll off meaning your speakers will be less bright or lose details in the high frequency range. The next is inductance, when a charge moves through a wire it generates a magnetic field. An audio signal is constantly changing therefore its intensity the magnetic field can change as well. The longer the wire the more magnetic field around it. when the signal changes the magnetic field tends to hang around for a small bit of time. because the magnetic field is created after the signal goes through it the current it induces back into the wire is out of phase also causing high frequency roll off. Inductance is lower in priority because it mostly effects current rather then voltage. The next is resistance which because RCA audio is a high impedance the resistance is irrelevant because the resistance of going through the equipment is so high it is literally thousands of time larger then in a cable. How are all these combatted? For capacitance you want to space the conductors away from one another but inductance you want them closer, for shielding you want a thick layer of copper braid or aluminum foil surrounding the center conductor. Ideally you want a precise balance of how close or far the conductors are so the only solution is shrinking the conductor. Decreasing the surface area therefore less capacitance and less inductance for more resistance you make the conductor thicker but with high impedance loads you can make it about as thin as you want with the exception of shielding. Because the shielding has less resistance then the center conductor so the faraday effect can take place which is also helped by the high impedance of the format. With all that said this is by far the best cable you can get all science included sturdy build, thick copper shielding, small center conductor, great connectors and of course USA made. With all that said here are some measurements i did with a DER EE DE-5000 LCR meter at 10khz where i found the best results i compared belkin, acoustic research, monster cable, wireworld audioquest and some DIY ones i had from mogami 2534 mic cable and a shortened monster component cable with new connectors. The lower the numbers here the better :

As for budget cables, these purely analog RCA Blue Jeans cannot be beat.

I did a "direkt" comparison between these LC-1's - as an interconnect set between my integrated amplifier and CD Player, Phono Preamplifier, and [from] Phono Preamplifier to Turntable (replacing Pro-Ject's phono interconnects while stripping off its ground wire).

Initially, I went for Kabeldirekt cables purchased here on Amazon as interconnects. I didn't know any better: they were certainly quieter and more snug than any cheap-o supplied RCA cables.

Then, I upgraded to BJC. And, in so many words, the difference between the Kabeldirekts and the BJC 1's was surprisingly profound. For a mere $20 more (as of the writing of this review), the Blue Jeans cables supplied a blacker background, eliminated any hiss from electrical power cabling a foot away (my audio system is, well, compactly organized) and, finally, revealed what was already in the vinyl or CD - very quiet passages were, indeed, very quiet and in a word the dynamics of, for instance, Bach (Hilliard Ensemble- Bach's motets CD), were brought to bear in a way that I've never heard before... no hiss at moderate-high volume levels.

This is my first major, and probably for a while to come, only cable upgrade investment and BJC provides needed shielding and seemingly transparent transmission with no loss.

BJC, unlike many cable manufacturers (esp. at this price range), details the construction of their products on their website. The double copper braiding, the foamed-air dielectric... All seem well to my ears and, CRUCIALLY for analog transmission, shields against EMI interference from power cables, etc.

I hear-tily recommend these cables as a good if not essential upgrade over the cheaper cables you may find online here and elsewhere. I already mentioned one product above that did not simply shield well against EMI despite the foil wrapping. The BJC LC-1's are very thick, but flexible enough to function as interconnects between components. The RCA clasp is sturdy, tight enough so that there is a satisfying 'snap' when you push the cable tip onto the female RCA connection.

I cannot speak for BJC versus the more expensive brands of analog RCA cabling, but as for assembling a decent mid-fi (ie not spending $1000s on audio components) audio system, you cannot go wrong with these.

Did I mention these BJ cables are made in USA? In times when every mid-fi component CD player or amplifier or speaker is made in China, it seems that the US & A is still making top-quality cabling!

Highly recommended: Very significant - indeed, for me, necessary - upgrade from Kabeldirekt and/or generic RCA cables that come with audio equipment.

I have purchased five 3-foot LC-1 interconnects, a subwoofer cable, and a digital coax from Blue Jeans Cable here on Amazon and have yet to be disappointed in terms of value (price-wise), audio fidelity preservation, and that adept attenuation of hiss and noise which initially made me think "why didn't I buy these in the first place?"

Just what I needed to keep the recommended load capacitance for the Audio Technica VM540ML under 200pF total. My phono stage input capacitance is 100pF, the tonearm wires are ~28pF and 1m of BJC LC-1 cables is ~36pF for a total of 164pF. Well under 200pF. It sounds great.

Not much to say about what all the five-star reviews have said. I'm using the Blue Jeans for my Mofi Ultra turntable (Ortofon LVB cartridge) hook to the Marantz PM8006 with MartinLogan XTi 60. With great depth and soundstage, I can not be happier with the sound I hear.

This cable eliminated a tracking shadow I had isolated to a cable supplied by the component manufacturer.

Quality matters.
