Vinyl has made a genuine comeback, and that is mostly a good thing. The problem is that the comeback has been accompanied by a wave of marketing nonsense aimed at people who are new to the format. Turntable companies are selling $500 accessories for $80 turntables, and audiophile publications are implying that you need a four-figure investment to play records properly. You do not. What you need is a decent turntable, correct setup, and a basic understanding of what actually affects the sound.

Most of the performance in a turntable system comes from setup, not from the hardware. A properly set up $300 turntable will outperform an improperly set up $1,000 turntable every single time. The setup is free. It just requires patience and a willingness to learn a few mechanical concepts.

Tracking Force: The Weight on the Stylus

Tracking force is the downward force that the tonearm applies to the stylus as it sits in the record groove. It is measured in grams and set using the counterweight on the back of the tonearm. Every cartridge has a recommended tracking force range specified by the manufacturer — typically between 1.5 and 2.5 grams for most moving magnet cartridges.

Setting tracking force correctly is the single most important adjustment on a turntable. Too light, and the stylus skips across the groove rather than tracing it, causing mistracking distortion on loud passages and accelerating record wear because the stylus bounces and gouges rather than sitting stably. Too heavy, and the stylus presses harder into the groove walls than the record material can withstand, increasing wear and potentially distorting the sound by compressing the groove walls.

Use a digital stylus force gauge — they cost about ten to fifteen dollars and are accurate to 0.01 grams. Do not rely on the tonearm's counterweight markings, which are rough approximations. Set the force to the middle of the manufacturer's range. If you hear distortion on loud passages, increase force in 0.1-gram increments until it disappears.

Key point: A common myth is that lighter tracking force is always better for record preservation. This is backwards. A stylus tracking below the recommended force mistracts, which damages records more than tracking at the correct (higher) force. Follow the manufacturer's specification.

Anti-Skate: Counteracting Physics

As the tonearm swings across the record, geometry and friction pull it toward the center — this is skating force. Without compensation, the stylus presses harder against the inner groove wall, creating uneven wear and channel imbalance.

Anti-skate applies an outward force to counteract this. Most turntables provide adjustment via a spring, weight, or magnetic mechanism. Set anti-skate equal to tracking force as a starting point — 2.0 grams tracking force means 2.0 anti-skate.

Perfect anti-skate is impossible because the skating force changes with groove modulation. The goal is a reasonable average. If you are obsessing over anti-skate beyond the initial setup, you are spending time on diminishing returns. Set it approximately right and move on.

Cartridge Alignment: Baerwald, Stevenson, and the Rest

A tonearm traces an arc, but the groove was cut in a straight line on a lathe. This mismatch means there will always be some tracking angle error, which causes distortion. Alignment geometries minimize this error. The two most common are:

  • Baerwald — Minimizes the maximum tracking error across the record surface. This is the most widely recommended alignment and the one most alignment protractors are designed for. It produces two null points (zero-error points) placed to reduce the worst-case error equally across the inner and outer grooves.
  • Stevenson — Places one null point at the innermost groove, minimizing error where the groove radius is smallest and the effect of tracking angle error is greatest. This tends to produce lower distortion on the last tracks of a record at the expense of slightly higher distortion on the outer tracks. Many Japanese turntable manufacturers use this alignment at the factory.

For practical purposes, Baerwald and Stevenson cover the ground. The difference between them is audible only on inner-groove passages; the difference between either correct alignment and a sloppy alignment is far more significant.

To align a cartridge, use an alignment protractor — a printed template placed on the platter. Position the stylus on each null point and adjust the cartridge in the headshell until parallel to the grid lines. Good lighting and a magnifying glass help. It takes fifteen minutes and is done until you change the cartridge.

Cartridge alignment is fiddly and slightly tedious, but it is not optional. A misaligned cartridge produces measurable distortion on every record you play, and it wears your records unevenly. Take the time to do it properly once, and it is done until you change the cartridge.

Moving Magnet vs. Moving Coil Cartridges

Turntable cartridges come in two fundamental types: moving magnet (MM) and moving coil (MC). The names describe the generator mechanism that converts the stylus's mechanical movement into an electrical signal.

Moving magnet (MM) cartridges have a magnet on the cantilever that moves between stationary coils, producing a relatively high output (3-5 millivolts). They work with any standard phono preamp and the stylus is replaceable. Most cartridges in the $20-300 range are MM designs.

Moving coil (MC) cartridges reverse the arrangement — coils on the cantilever move within a stationary magnetic field. The lighter moving element can theoretically respond faster, but the output is much lower (0.2-0.5 millivolts), requiring a step-up transformer or phono preamp with MC input. The stylus is usually not user-replaceable.

MC is not automatically better than MM. Below about $400, MM is the better value. Many experienced listeners prefer quality MM cartridges at any price for the practical advantage of replaceable styli.

Phono Stages: What They Do and When to Upgrade

A phono stage amplifies the cartridge's tiny signal to line level and applies RIAA equalization — an inverse curve that corrects for the EQ applied during record cutting. Records are cut with boosted treble and reduced bass, and the phono stage restores the original tonal balance.

Many receivers have a built-in phono stage on the "Phono" input. For MM cartridges, these are usually perfectly adequate — correct RIAA curve, sufficient gain, low noise floor. The internet will tell you an external phono preamp is transformative. In controlled listening tests with level matching, the difference between a decent built-in stage and a $200 external unit is subtle to inaudible for most listeners.

Key point: If your receiver has a phono input, use it before spending money on an external phono stage. If the noise floor is audible (hiss or hum at listening volume with no record playing) or the sound is obviously wrong (dull, distorted, or thin), then an external stage is warranted. Otherwise, your money is better spent on a cartridge upgrade or more records.

External phono stages become more relevant with MC cartridges, where the extra gain requirement means a dedicated preamp with an MC input will typically perform better than a receiver's phono stage running through an inline step-up transformer. If you are running an MC cartridge, budget for a phono preamp with a proper MC input and adjustable loading.

The Turntable Itself: What Matters

The turntable's job is to spin the record at a constant speed with minimal vibration. That is it. Everything else is secondary. The key specs are:

  • Speed stability: Wow and flutter below 0.1% is inaudible. Modern belt-drive and direct-drive turntables are generally fine here.
  • Isolation: A heavy plinth and compliant feet prevent surface vibration from reaching the stylus. This is where you feel the difference between a $150 turntable and a $300 one.
  • Tonearm quality: The tonearm should be rigid and move freely in its bearings. Cheap turntables cut costs here more than anywhere else.

Avoid turntables with built-in speakers, without a counterweight on the tonearm, or marketed primarily on aesthetics. Suitcase turntables and novelty designs will damage your records and sound terrible.

Practical Setup Checklist

  1. Place the turntable on a stable, level surface away from speakers (vibration feedback causes low-frequency rumble).
  2. Level the turntable using the adjustable feet and a bubble level.
  3. Balance the tonearm so it floats horizontally with zero force, then set tracking force to the cartridge manufacturer's recommendation using a digital gauge.
  4. Set anti-skate equal to tracking force as a starting point.
  5. Align the cartridge using a protractor (Baerwald for general use).
  6. Connect to the phono input on your receiver, or to an external phono preamp connected to a line input.
  7. Play a record. If it sounds distorted on loud passages, increase tracking force in 0.1g increments. If one channel is louder than the other, recheck alignment and anti-skate.

This takes thirty minutes the first time. Once done, it needs no maintenance until the stylus wears out (500-1,000 hours for MM, longer for MC) or you change the cartridge.
