Why the set-up matters more than the next upgrade

Vinyl is a mechanical format, and every mechanical format rewards patience. A modest turntable that has been levelled, balanced and aligned properly will comfortably outperform an expensive one that has been dropped onto a sideboard and plugged in. That is because the stylus has to trace a groove that is measured in fractions of a millimetre, and anything that pulls it off centre — a tilted platter, too much or too little downward force, a misaligned cartridge — introduces distortion you will hear as harshness, sibilance or a muddled stereo image.

Worse, a badly set-up deck wears your records. Play a prized pressing with excessive tracking force night after night and you are effectively carving the damage in permanently. The good news is that the checks below take about twenty minutes and need nothing more exotic than a spirit level, a small screwdriver and a set of scales.

Give yourself a clear hour, work on a stable surface with decent light, and switch the deck off at the mains before you start touching anything.

Level the deck and the platter first

Everything else depends on this. If the plinth is not level, the platter is not level, and the tonearm will tend to drift down one side of the record. Begin with the shelf or stand: it should be rigid, ideally on a wall bracket or a solid low unit, well away from the speakers and from anything with a motor inside it.

• Place a small spirit level on the platter and check front-to-back, then side-to-side.
• Adjust the deck's feet, or slip thin shims under them, until the bubble sits centrally in both directions.
• Check the platter itself sits flat on its bearing and spins true with no visible wobble.
• Confirm the deck is not rocking — press gently on each corner in turn and feel for movement.

If the platter is level but you notice a gentle rise and fall at the edge when it turns, the record may simply be slightly warped, which is a pressing issue rather than a set-up one.

Balance the tonearm before you dial in any force

Now the counterweight at the back of the arm. The aim is to find the point at which the arm floats horizontally, with the stylus just clear of the platter. This gives you a known zero from which tracking force can be added accurately.

• Release the arm from its rest and lower the cueing lever so the arm is free to move.
• Turn the counterweight until the arm hovers parallel to the platter, floating on its own, neither diving nor rising.
• Set the numbered ring on the counterweight to zero without turning the weight itself — hold the weight still and rotate only the scale.
• Rotate the counterweight forwards to dial in the required force. One full turn usually equals about two grams on most arms, so read the scale carefully.

If your deck has a digital stylus gauge, use it. They cost little and remove all guesswork, especially on arms where the markings are vague.

Set tracking force within the maker's range

Every cartridge comes with a recommended tracking force range, typically something like 1.8 to 2.2 grams. Start in the middle, not at the bottom. Too light is not the safe option people assume: a stylus that skips over the groove modulations will mistrack, producing gritty distortion on loud passages and, over time, more damage than a correctly weighted one.

Settle on a figure in the upper half of the range if you value stability and clean tracking of dynamic music, but never exceed the maximum. Then leave it alone for a week and listen properly before fiddling again.

Anti-skate, alignment and the finer adjustments

As the arm travels towards the centre of the record, friction drags it inwards. Anti-skate, or bias, counteracts that pull. Set it to match the tracking force as a starting point, then fine-tune by ear. If the right channel sounds brighter or more distorted than the left, you have too little bias; if the left sounds thin, you have too much.

Cartridge alignment matters just as much. The stylus needs to sit square in the headshell and follow the arc the maker intended, usually set with a simple paper protractor. Loosen the mounting screws just enough to nudge the cartridge, and tighten them in a diagonal pattern so it does not shift as you work.

• Set vertical tracking angle so the arm tube sits roughly parallel to the record surface when playing.
• Check azimuth — viewed from the front, the stylus should sit vertically in the groove, not leaning.
• Confirm the arm's lift and cueing drop slowly and land the stylus cleanly, not with a thump.

Keep it clean and revisit the set-up

A carbon-fibre brush before every side, a stylus brush after, and a proper wet clean for second-hand records will do more for sound quality than most tweaks. Replace the stylus when it is due, and check tracking force and alignment after any move, any cartridge change, or if you start hearing sibilance, inner-groove distortion or a channel imbalance creeping in.

That occasional ten-minute check is the whole secret. Small, careful adjustments, made with the music off and the deck unplugged, keep your records sounding their best and keep them safe for decades of listening.
