Fluance RT81 vs AT-LP120XUSB

The verdict, before the forty rows

These are the two decks this site recommends more often than any others, and until now they have never been put side by side. The Fluance RT81 is the top pick on six of our roundups. The Audio-Technica AT-LP120XUSB is the deck we point at every time somebody wants to digitize records or learn to set an arm up properly. They sit close enough in price to be cross-shopped and they are built on opposite philosophies.

The short answer: buy the RT81 if you want the better-looking, quieter-on-paper, narrower deck to play albums through speakers, and the AT-LP120XUSB if you need 78 RPM, a USB output, or a cartridge whose replacement parts still exist. Those three rows decide most purchases, and only one deck has any of them.

What does not decide it is the drive system, despite being the headline difference. We have not measured either turntable — what we do instead is read what each maker publishes and refuse to compare figures measured differently. Which, on this page, turns out to be most of them.

Belt against direct: what actually changes

Fluance builds the RT81 as a belt drive with a DC motor on three-point rubber isolation. The motor sits off to one side, a rubber belt carries its rotation to the platter, and the belt absorbs some of the motor’s vibration on the way — that is the entire engineering argument for belt drive, and it is why nearly every deck at this price uses one. The cost is a consumable: belts stretch, and a stretched belt shows up as speed drift.

Audio-Technica builds the AT-LP120XUSB as a direct drive with a DC servo motor under the platter. There is no belt to replace. Audio-Technica publishes starting torque above 1.0 kgf.cm and an electronic brake, which is why the platter is up to speed almost immediately and stops when told — the DJ-descended behavior that also makes it the deck of choice for anyone cueing by hand.

Neither arrangement is inherently the better-sounding one, and we lay the general case out in belt drive versus direct drive. What you should take from this section is narrower: the Fluance trades a maintenance item for a little vibration isolation, and the Audio-Technica trades that isolation for immediacy and one fewer thing to buy.

The three things only the Audio-Technica can do

78 RPM. Fluance’s own table prints 78 RPM: No. Audio-Technica publishes 33-1/3, 45 and 78 RPM and describes the deck as 3-speed. If there is shellac in the house — a parent’s collection, an estate sale box — this row ends the comparison on its own. The honest footnote is that proper 78 playback also wants a dedicated 78 stylus, which is a much wider groove than the elliptical tip either deck ships, so the Audio-Technica lets you play them where the Fluance cannot, not that it plays them ideally.

A USB output. Audio-Technica publishes 16 bit at 44.1 or 48 kHz, selectable, over a USB 1.1 compliant interface. That is CD resolution, not hi-res, and it is enough for archiving a collection to files. The RT81 has no USB at all. You can still digitize from it — our guide to recording vinyl to a computer covers the audio-interface route that works with any deck — but that is another box and another cable.

A cartridge with a future. This is the row nobody notices and the one we would weight most heavily. The RT81 ships an Audio-Technica AT95E. On Audio-Technica’s own site that cartridge is badged Discontinued, and so is its only listed replacement stylus, the ATN95E, whose page reads We’re sorry, but this item is unavailable. The AT-LP120XUSB ships an AT-VM95E — the current half-inch line — on a standard AT-HS6 headshell, and Audio-Technica lists five VMN95 styli as compatible with that body, from the conical VMN95C up to the Shibata-profiled VMN95SH.

So the Fluance’s stock cartridge is a dead end, and the Audio-Technica’s is the start of a ladder. That is fixable on the Fluance — it has a standard H-4 bayonet headshell, so any half-inch cartridge fits, and our cartridge roundup and fitment explainer cover how — but fixing it is a purchase, and that purchase belongs in the price comparison.

The two things only the Fluance can do

Fit. Audio-Technica publishes 452.0 mm (17.80 in) wide and 8 kg (17.6 lb). Fluance publishes 16.5 in wide and 14.1 lb. Two and a half inches sounds academic until you shop for somewhere to put it: Fluance’s own IB40 isolation base publishes a footprint limit of 17.13 x 14.96 in, which the AT-LP120XUSB exceeds and the RT81 clears easily. Our isolation feet and platforms roundup ranks on exactly this, and the wide deck rules several products out.

Stop by itself. The RT81 has a defeatable auto-stop: at the end of a side the platter stops, even though you still cue the arm yourself. The AT-LP120XUSB is fully manual — Audio-Technica’s own table says so — which means a record that finishes while you are in another room keeps turning with the stylus sitting in the run-out groove. Neither is a sound-quality matter. Both are things you will notice weekly for years. If that is the deciding factor for you, read automatic versus manual turntables and consider an actual automatic instead.

The numbers that look decisive and are not

Fluance publishes wow and flutter of 0.2%, speed variation of +/- 1.00% and a signal-to-noise ratio of 67 dB or higher, A-weighted, 20 kHz LPF — plus 60 dB or higher unweighted. Audio-Technica publishes wow and flutter below 0.2% WRMS at 3 kHz (33 RPM) and a signal-to-noise ratio of more than 50 dB, with no weighting stated and no speed-variation figure at all.

Read those as two companies describing their own products on their own terms, because that is what they are. A-weighting flatters a noise figure by discounting the frequencies the ear is least sensitive to, so Fluance’s 67 dB and Audio-Technica’s 50 dB are not seventeen decibels apart in any meaningful sense. The same applies to the wow-and-flutter pair: one is a plain percentage, the other is weighted RMS at a stated test frequency. The only sound conclusion is Fluance publishes a more complete specification, which is worth something in itself, and that both decks are in the ordinary range for belt and direct drives at this money.

Two rows are genuinely comparable, because both makers publish the same thing in the same units. The line outputs differ — 140 mV against 240 mV — which means the Audio-Technica plays louder at the same volume setting, and nothing more. And the supported cartridge weight ranges differ: Fluance supports 3.5–6.5 g, Audio-Technica 3.5–8.5 g. That extra two grams is real headroom if you ever want a heavier cartridge, which is the one place the arm specs actually point in the same direction as the upgrade story.

Setting each one up

Both are manual decks with adjustable counterweights and anti-skating, so both require the same job: fit the headshell, balance the arm, set the tracking force, set anti-skate, level the plinth. Our turntable setup guide and tonearm balancing guide walk through it, and a tracking-force gauge is how you confirm the number rather than trusting the dial.

Two differences matter in practice. The Audio-Technica publishes a tracking-force adjustment range of 0 to 4 g, a maximum tracking error angle of less than 3 degrees and +/- 5 mm of overhang adjustment at the headshell, which is the kit for aligning a cartridge properly; Fluance publishes none of those three figures. Against that, the Audio-Technica also gives you more ways to get it wrong, which is exactly why we recommend it to people who want to learn and the Fluance to people who do not.

The Audio-Technica also ships a stylus target light, which sounds like a gimmick until you cue by hand in a dim room. And both decks publish a ground terminal and a switchable stage, so if you later add an external phono preamp, connect the ground wire before you conclude the preamp hums.

Who should buy which

Buy the Fluance RT81 if this is the only deck you plan to own. It is quieter on its own published terms, it is the better-looking object by a distance — a real wood veneer over MDF against a plastic-topped plinth — it stops itself at the end of a side, and it fits on shelves and isolation platforms the Audio-Technica does not. Budget for a current cartridge, and read the full RT81 review for why.

Buy the AT-LP120XUSB if you want to do things to your records rather than just play them. Digitizing, 78s, cartridge experiments, learning alignment properly: this is the deck with the torque, the adjustments, the parts supply and the port. It is bigger, heavier and plainer, and it does not care. The full AT-LP120XUSB review covers what fully manual really asks of you.

Buy neither if you will not cue an arm by hand. Both of these are manual decks, and a surprising number of people discover that about themselves in week two. The honest alternative is an automatic that still keeps an upgradeable stylus — the AT-LP70X — or the wider field in best automatic turntables.

Whichever you pick, neither makes a sound by itself. Both will drive powered speakers straight out of the box on their line setting, which remains the cheapest complete system we know how to recommend.
