E Series – A Goal of Neutrality

The goal for the Connect it E series cables was to create transparent-sounding audiophile cables at a reasonable price. In short, these are cables that “get out of the way.” We focused on quality core materials like a high-purity copper conductors & effective shielding for a lossless transmission of a given audio signal. All E Series connectors (including our True Balanced mini XLR plugs) feature gold-plated brass connectors to ensure ideal & long-lasting conductivity. The line & phono cables (excluding the True Balanced ones) are semi-symmetrical. This means that the shielding is only connected to the signal at one end, therefore the end marked with yellow tags should be connected to the signal-receiving device. This is because Pro-Ject turntables (the ‘tables without built-in preamps) are configured with balanced RCA outputs.

Why Cable Quality Matters

Quality cables don’t make your gear sound better as much as they can pass along the full extent of the musical information that that gear can convey. A good cable ensures the transfer of detail & spacial information from one piece of gear to another while rejecting external interference that manifests as noise. Using a poorly designed cable can limit the potential of your hi-fi setup and can definitely exacerbate the “bottleneck effect.” Some folks compare it to automotive concepts; a sports car’s engine is equally powerful with good tires and bad ones, but take that car to the road with bad tires and you’ll be missing out on the full experience. The same applies to sound systems. Good turntables, phono preamps & amplifiers need quality cabling so that their potential can be actualized & delivered to your ears!

Our “Connect it” cable lineup offers different connection types & technologies as well as various conductor, shielding & connector materials. As usual with Pro-Ject, we’ve got a cable for everyone, and each one reliably out-performs its price. With 30+ years experience in hi-fi, we’ve developed four cable series that cover all your analog needs.

Pro-Ject Audio Cables Overview

To clarify the nomenclature, take the example of our standard phono cable that ships with most turntables: Connect it Phono E RCA. All cables are designated Connect it. The term Phono means it’s designed for the phono signal (always with ground whether balanced or not). refers to the cable series and of course, RCA clarifies the cable termination. The same formula applies to specialty (balanced) and line-level cables. Thusly, Connect it Line E RCA is a conventional line-level RCA cable without grounding spades, and Connect it Phono E RCA > Mini XLR refers to the E Series balanced phono cable that connects a turntable’s RCA output to a phono preamp’s balanced mini XLR input (as with Phono Box S3 B & DS3 B, Tube Box DS3 B). Keep in mind that anything with a mini XLR connector, standard XLRs or 5-pin DIN is a balanced cable and should be used in that context. Also note that LS is the designation for all speaker cables (Connect it LS E, LS S, LS DS & LS RS).

The E, S, DS & RS designations mirror our electronics’ nomenclature and can be viewed respectively as good, great, better & best! Like our electronics have increasingly sophisticated circuitry & features as you climb up the line, our cable series improve in quality with better signal conductors, shielding, dielectrics & connectors.
