Phono Cables – Pure Connection for Analog Sound
A good phono cable is much more than just a connection—it’s the key to a clear, noise-free music signal between the turntable and the amplifier. Especially with sensitive moving-magnet (MM) or moving-coil (MC) systems, the quality of the cable makes an audible difference. At Klangheimat, you’ll find a carefully curated selection of turntable cables from renowned manufacturers such as Cardas, Van den Hul, Kimber Kable, and AudioQuest.

Why use special turntable cables?
A phono cable must transmit extremely delicate analog signals—and do so over the shortest possible distance without interference. While a high-level RCA cable delivers around 200 mV, the signal from an MM system ranges from 3 to 5 mV, and an MC system typically outputs only 0.2 to 0.5 mV. At these levels, even the slightest interference is immediately noticeable as hum, noise, or extraneous sounds. That’s why shielded, low-capacitance turntable cables with precision connectors are used here—cables that also reliably route the separate ground wire.
What Makes a Good Phono Cable
High-quality phono cables use oxygen-free copper (OFC); top-of-the-line models use monocrystalline copper (OCC) or the finest silver strands. Crucial is the multi-layer shielding—usually a combination of foil and dense braiding—which protects the signal from electromagnetic interference. Equally important are the capacitive properties: the capacitance per meter should be as low as possible, measured in picofarads, because in MM systems, the total capacitance of the cable and the input stage directly determines the frequency response in the high-frequency range. A separate, low-impedance ground wire prevents ground loops and potential differences between the tonearm and the phono preamplifier.

MM Systems
Output voltage 3–5 mV. Sensitive to the total capacitance of the cable and phono input. Low cable capacitance is essential.
|
MC Systems
Output voltage 0.2–0.5 mV. Capacitance plays a lesser role, but excellent shielding is absolutely crucial.
|
Balanced (XLR)
True balanced phono transmission—only practical with MC systems and balanced phono preamps. Maximum signal-to-noise ratio.

Connections, Plugs, and Connection Types
On the turntable side, three connection types are common: fixed RCA jacks on the turntable, a 5-pin DIN plug on the tonearm, and, increasingly, XLR jacks for balanced transmission. On the phono preamp side, the corresponding connector is almost always RCA (Cinch) or XLR. The choice of the correct connection type depends on the turntable, tonearm, and phono preamp—ideally, the cables should be as short as possible, with high-quality, mechanically secure connectors and neatly soldered joints.
Tonarm DIN, RCA, or XLR—which one when?
High-quality tonearms—such as those from Rega, SME, or Linn—output the signal via a 5-pin DIN connector. This results in the shortest signal path: the tonearm’s internal wiring runs directly and continuously all the way to the phono cable. RCA jacks on the turntable chassis are convenient, but they require an additional solder joint and usually involve a second, shorter internal run. XLR phono is the most uncompromising option: ground-free and immune to hum, though it only makes sense if both devices have true balanced phono circuits.
Ground Wire—Why It’s Indispensable
Unlike a standard audio cable, every phono cable carries an additional ground wire—usually as a separate black cable with a terminal on the phono preamp. This wire connects the tonearm chassis or the tonearm tube joint to the ground point of the phono stage and prevents potential differences. If the connection is missing or has poor contact, this results in a clearly audible 50-Hz hum. High-quality phono cables use solid cable lugs or banana plugs with a large contact cross-section for this purpose.
Understanding Capacitance—The Key Metric for MM Systems
In moving-magnet cartridges, the cartridge inductance, the phono stage’s input impedance (typ. 47 kΩ), and the total capacitance of the cable plus the phono input form a resonant circuit that determines the frequency response in the high-frequency range. Most MM manufacturers specify an optimal range of approximately 100–300 pF. High-quality phono cables typically have 50–100 pF/m, so that both components—the cable and the input stage—together fall within the correct range. At Klangheimat, we’d be happy to advise you on which cable is best suited for your cartridge and phono preamp.

Which phono cable is right for your system?
A high-quality turntable-to-amplifier cable minimizes signal loss, reduces hum, and ensures a balanced sound. The choice depends on three factors: cartridge type (MM or MC), connection type (RCA, DIN, or XLR), and phono input. We recommend selecting a cable that matches the class of your cartridge and phono preamp—a €2,000 MC system deserves more than a standard cable.

FAQs About Phono Cables
What’s the difference between a phono cable and a standard RCA cable?
A phono cable transmits extremely low signal levels in the range of a few millivolts—a standard RCA cable handles levels that are about 50 to 1,000 times higher. Therefore, a phono cable requires particularly dense shielding against electromagnetic interference, the lowest possible capacitance per meter, and a separate ground wire. Visually, both cable types look similar—but electrically, the requirements are significantly different.
MM or MC—Does Each System Require a Different Cable?
Both systems have different requirements. For MM systems, cable capacitance is crucial, as it—together with the input capacitance of the phono stage—determines the high-frequency response; a cable with low, defined capacitance (typically 50–100 pF/m) is essential here. MC systems are less sensitive to capacitance, but excellent shielding is all the more important due to the extremely low signal levels. Many high-quality phono cables are designed to perform optimally with both system types.
What is the purpose of the separate ground wire?
The ground wire connects the turntable’s chassis or tonearm to the ground point of the phono preamp stage. It ensures that both devices are at the same ground potential, thereby preventing ground loops. If the connection is missing or has poor contact, this results in a clearly audible 50-Hz hum. That’s why good phono cables feature sturdy cable lugs or banana plugs with a generous contact cross-section.
How long should a phono cable be?
As short as possible, as long as necessary. Standard lengths are 1.0 to 1.2 m—at these lengths, the total capacitance remains within a non-critical range and interference is minimal. For MM systems, cable length is particularly critical due to capacitance; a significantly longer cable can noticeably alter the frequency response. MC systems are less sensitive to length, but even here, the cable should be kept as short as necessary.
What do the pF specifications on phono cables mean?
Picofarad (pF) indicates the capacitance per meter. This adds to the input capacitance of the phono stage to form the total capacitance, which, together with the cartridge’s inductance, determines the resonance range in the high frequencies. MM manufacturers typically specify a range of 100–300 pF within which their system operates optimally. For example, a cable with 80 pF/m and 100 pF input capacitance results in a total capacitance of 180 pF—a value that is typically not a concern.
RCA phono or XLR phono—which is better?
XLR phono is, in principle, the more uncompromising solution, as it uses balanced transmission and effectively suppresses common-mode interference. However, this requires that both the phono stage and the tonearm are truly balanced—a simple XLR cable connected to an unbalanced input offers no advantage. RCA-Phono is the most versatile solution and, when properly assembled, delivers sound quality at the highest level.
My turntable has a 5-pin DIN connector on the tonearm—what does that mean?
High-quality tonearms from Rega, SME, Linn, or Pro-Ject route the signal directly from the tonearm tube to the outside via a 5-pin DIN connector—without any additional soldering inside the turntable chassis. This results in the shortest possible continuous signal path. For this, you’ll need a phono cable with a DIN connector on one end and a RCA or XLR connector on the other. With this setup, a particularly high-quality cable really pays off in terms of sound quality.
Is a high-quality phono cable worth it even for an entry-level turntable?
For an entry-level turntable in the €300–500 range, an €800 phono cable will rarely be worthwhile, but a good cable in the €100–250 range can already audibly reduce hum and stabilize the soundstage. As a general rule, the cable should match the class of the cartridge and phono preamp. Higher-end systems benefit more significantly from an audiophile phono cable.
How do I reduce hum in my turntable system?
Hum almost always has one of three causes: a missing or poorly connected ground wire, a ground loop caused by multiple ground points, or electromagnetic interference. First, check the ground connection on the phono preamp, keep the phono cable clearly separated from power cords, and avoid stacking the turntable and phono preamp on top of each other. A high-quality, well-shielded cable is an important foundation here.
Which manufacturers have proven themselves in the field of phono cables?
In the audiophile segment, manufacturers such as Cardas, Van den Hul, Kimber Kable, and AudioQuest have particularly established themselves. Cardas is known for its smooth, organic sound signature; Van den Hul for its detailed, neutral phono cables; Kimber Kable for its characteristic braided strand structure; and AudioQuest for a consistently tiered product line ranging from entry-level to reference class.
