How to Level a Turntable

The short answer: put a small spirit level on the platter, read it left-to-right and front-to-back, and correct the low side — with the deck’s own feet if it has adjustable ones, with thin firm shims if it does not, and by leveling the furniture if the surface itself slopes. It takes about five minutes, it costs nothing, and it removes a fault that no cartridge, mat or isolator will compensate for.

Why level matters more on a turntable than on anything else

A stylus is held in the groove by a tracking force measured in grams — 1.8 to 2.2 g for an Audio-Technica AT-VM95E, 1.6 to 2.0 g for an Ortofon 2M Red. That force is gravity acting straight down on a very small, very compliant suspension. Tilt the whole assembly and you split that force into a smaller downward component and a new sideways one, pulling the stylus toward the low side of the deck for the entire side of the record.

Two things follow. The first is that the stylus is now bearing harder on one groove wall than the other, which is a channel imbalance and an uneven wear pattern at the same time. The second is that your anti-skate setting is wrong, because anti-skate exists to cancel one specific inward force — the one produced by a pivoted arm tracking an arc — and it was set with no knowledge of your furniture. Adding a second, constant sideways force means the compensation no longer matches the problem.

On a suspended-subchassis deck there is a third consequence: the suspension is designed to sit at a particular attitude, and a leaning plinth loads the springs unevenly. That is a less common design at the prices this site covers, but if you own one, level is not optional.

Measuring it properly

Three rules make the measurement trustworthy. Measure on the platter, near the spindle, because the record sits on the platter rather than on the plinth — and because plenty of plinths have a rim, a texture or a slope that will not take a level flat. Measure twice, ninety degrees apart, because a deck can be level left-to-right and leaning front-to-back; those are two independent corrections. Stop the platter and take the record off first.

A cheap bubble level is the better tool here, and we do not rank one — there is no product on this site for it, because a two-dollar spirit level from a hardware store has nothing to calibrate and nothing to go wrong. A phone app works too, with one sanity check: read it, rotate the phone 180 degrees, and read again. If the sign flips instead of staying the same, the phone has an offset and you are chasing its error rather than your deck’s.

Correcting it: three cases

Case one, the deck has adjustable feet. Most decks above entry level do: the feet screw in and out. Turn the low foot out or the high foot in, in small increments, re-measuring after each one. Work one foot at a time — on a three-foot deck every adjustment changes both axes, so iterate rather than trying to solve it in one pass. Fluance publishes adjustable feet on the RT81+, for example; many decks at the same price do not.

Case two, the feet are fixed. Shim under the low feet with something thin, firm and non-compressible: index cards, thin cork sheet, plastic washers, or the shims sold for furniture. Do not use foam, folded paper or sticky pads — they compress at different rates under different loads, so the deck is level on the day and leaning a week later. Keep the shim smaller than the foot so the foot still carries the load through its own contact patch.

Case three, the surface slopes. This is the one people try to solve at the deck and should solve at the furniture. An old sideboard, a flexing shelf or a floor that runs downhill is not a problem a turntable foot has enough travel to fix. Level the furniture, add a rigid platform, or move the deck to a wall shelf you mount level.

What isolation products do and do not do

This is worth being blunt about, because the two jobs get confused constantly. Isolation decouples a deck from vibration. It does not level anything. IsoAcoustics publishes no adjustable feet for the zaZen I platform — it is a 17 by 15 inch dense-fiber slab rated to 25 lb, and it sits at whatever angle the shelf under it sits at. Compliant isolators are worse for this purpose, not better: a Vibrapod Model 2 is rated 4 to 8 lb per pod with a 6 lb optimum, so it compresses in proportion to the load it carries, and an unevenly loaded deck will settle unevenly.

Where isolation genuinely earns its money is the dynamic problem: footfall on a suspended floor, speaker energy coming back through the furniture, or a deck sharing a shelf with a subwoofer. A wall shelf is the strongest answer to the first of those — Pangea publishes a 40 lb rating for the Premier SE MKII with stud slots at 16 in on center and a 1 in cable gap — because it takes the turntable off the floor entirely. Our isolation picks rank that class properly, by published load rating and footprint.

After you level it

Re-check the tracking force. A gauge reads a weight, weight is gravity, and you have just changed the geometry that gravity acts through — so confirm the figure your cartridge maker publishes, with the gauge sitting on the platter rather than the plinth. Our force gauge picks explain why measurement height matters for exactly this reason, and balancing the tonearm is the full version of the job.

Then, if the symptom that brought you here has not gone away, it was not level. Skipping has four other common causes, which the skipping guide works through in order; a hum has three, in hum and grounding; and a wavering pitch is usually a belt or a speed setting rather than a surface, which troubleshooting covers symptom by symptom.
