Fluance RT81 vs RT82

Fluance builds its turntables the way a parts catalog would: one plinth, one platter, one arm, and a short list of things that change as the price goes up. The RT81 and the RT82 sit next to each other on that list, and their published specification tables agree on sixteen rows out of forty — the same MDF cabinet in the same veneer, the same 553 g aluminum platter, the same rubber mat, the same 224 mm static-balanced S-type arm with the same overhang and the same Litz wire, the same tinted dust cover, the same two speeds and the same defeatable auto-stop.

Three things change, and one of them changes in the wrong direction. The RT82 gets a servo-controlled motor and the two speed figures underneath it improve sharply. It gets an Ortofon OM 10 in place of an Audio-Technica AT95E, and an arm rated for heavier cartridges than the RT81’s. And it loses the built-in phono preamp entirely, which means it is not a working system on its own.

The question that decides it: do you already have a phono stage?

The short answer

• Buy the RT82 if your amplifier, receiver or speakers already have a phono input. You get a third of the published wow and flutter, roughly an eighth of the published speed variation, a current-production cartridge and an arm whose published support window reaches the Ortofon 2M series. The mechanical part of the deck is simply better, and you are not paying for electronics you intend to bypass.
• Buy the RT81 if you are plugging into powered speakers or any line input and want to play a record this week. Its switchable stage makes it complete on day one and its bypass switch means the stage does not become dead weight when you upgrade. Plan on a current cartridge as its first improvement.
• Look hard at the RT81+ before you do either. Fluance prices it level with the RT82, and it is the RT81 with the current Audio-Technica cartridge already fitted and the preamp kept. At that price the three-way choice is better motor, better cartridge, or both plus a preamp purchase.

Criterion one: the two figures the servo motor moves

Fluance publishes a speed variation figure and a wow-and-flutter figure for every deck it sells, which is unusual at this money and is the reason this comparison can be argued rather than asserted. For the RT81 they are plus or minus 1.00% and 0.2%. For the RT82 they are 0.13% and 0.07%.

The two are not the same complaint. Speed variation is how far from 33 1/3 the platter sits: a steady offset that makes an entire side play slightly sharp or slightly flat. As arithmetic, a 1% error is about seventeen cents of pitch, roughly a sixth of a semitone; 0.13% is a little over two cents. Wow and flutter is the wobble around whatever speed the platter has settled on, and it is the figure people are describing when they say a turntable warbles on sustained piano or strings.

What Fluance says it changed to get there is the motor and how the motor is mounted. The RT81 runs a plain DC motor on three-point rubber isolation. The RT82 runs a DC motor with a servo controller that, in Fluance’s own words, “analyzes motor speed 500 times/sec”, sitting on under-mounted seven-point silicone isolation with a decoupling ring. Since the platter, the belt, the arm and the plinth are identical between the two decks, the motor assembly is the only plausible source of the difference — which is a cleaner attribution than most upgrade steps allow.

Two honest caveats. These are the manufacturer’s figures, measured on the manufacturer’s terms, and we have not put either deck on a test bench; nothing on this page is a listening claim. And the noise figures move far less than the speed figures do — 67 dB A-weighted against 68.5 dB weighted — while the RT81 is actually the deck that publishes an unweighted number as well, at 60 dB or higher. Where a maker gives you two measurement standards and its dearer deck gives you one, the honest comparison is the one it publishes for both, and that gap is about a decibel and a half.

Criterion two: the preamp that disappears

This is the row that reverses the direction of the upgrade. Fluance’s RT82 table reads “Separate Phono Preamp Required”, and lists both the line output and the preamp bypass as not applicable. Its only output is the cartridge’s own 4.0 mV phono signal, which is far too quiet and has the wrong frequency curve for any ordinary input.

The RT81’s stage is switchable between PHONO and LINE, puts out 140 mV in LINE mode, and — the part that matters most — publishes a full bypass, so every one of its own electronics drops out of the path when you switch it off. That is why the cheaper deck is not the disposable one: you can plug it into powered speakers today and into a proper phono stage in two years without the internal circuit coloring anything on the way through.

So price the RT82 as a deck plus a stage. Three ways to cover it, in rising order of cost: an amplifier or receiver with a PHONO input, which you may already own; powered speakers with a phono stage inside, which turns a preamp-less deck into a two-box system; or a standalone box, which is the route our do I need a phono preamp explainer walks through. What you must not do is assume it will work into an aux input, because it will not — that is the single most common bad surprise in this price bracket, and it is the reason Fluance keeps the RT81 in the range at all.

Criterion three: one cartridge is still in production

The RT81 ships an Audio-Technica AT95E: dual moving magnet, 3.5 mV output, 20 dB of channel separation at 1 kHz, on Fluance’s figures a 0.4 x 0.7 mil bonded elliptical diamond tracking at 2.0 g. The RT82 ships an Ortofon OM 10: moving magnet, 4.0 mV, 22 dB of separation on Ortofon’s own table, an elliptical tip Ortofon gives as r/R 8/18 um, tracking at 1.5 g. On paper the OM 10 is slightly ahead on every row where the two makers publish the same measurement.

The bigger difference is not on either spec table. Audio-Technica’s own product page for the AT95E carries a Discontinued badge, and so does its page for the ATN95E — the replacement stylus Fluance names in the RT81’s own specification table — which additionally reads “We’re sorry, but this item is unavailable.” Ortofon, meanwhile, still lists and prices the Stylus 10 for the OM 10. A stylus is a wear part, not a fixture, so that is a real difference in what owning each deck looks like in a couple of years: the RT82 has a sanctioned re-tip and the RT81, from its own cartridge’s maker, does not.

There is a small, genuine contradiction worth reporting rather than smoothing over. Fluance publishes the AT95E’s tip as 0.4 x 0.7 mil; Audio-Technica’s own ATN95E page describes the same stylus as 0.3 x 0.7 mil. Both figures appear in the matrix above, credited to whoever published them, and we do not pick between them.

None of this makes the RT81 a bad deck. Its headshell is the same H-4 bayonet fitting as the RT82’s and its mount is the same standard half-inch, so the cartridge is a consumable you can replace with something current — and the obvious replacement is the AT-VM95E, which Audio-Technica publishes at 4.0 mV, 1.8 to 2.2 g and 0.3 x 0.7 mil, with six interchangeable VM95-series styli above it because, in its own words, all VM95 cartridges share one body. Our cartridges under $200 roundup covers where that sits against the alternatives, and how to set up a cartridge covers fitting one.

Criterion four: the ceiling each arm publishes

This is the row almost nobody quotes and it may be the most useful one on the page. Fluance publishes a supported cartridge weight for each arm: 3.5 to 6.5 g for the RT81 and 5.0 to 7.5 g for the RT82. The effective masses differ too, at 28.2 g and 21.78 g respectively, both of which Fluance states without saying whether the headshell is included.

Put the popular upgrades against those windows. The Audio-Technica AT-VM95E weighs 6.1 g, so it fits inside both. Ortofon’s 2M Red and 2M Blue are published at 7.2 g, which is above the RT81’s stated ceiling and inside the RT82’s — and Fluance’s own next rung, the RT83, is this same arm with a 2M Red fitted at the factory. The cartridge will physically bolt to either headshell; what differs is whether the maker of the arm says that mass is supported, and on the RT81 it says it is not. If an eventual 2M-series cartridge is part of the plan, that alone is an argument for starting at the RT82.

Ortofon’s own answer to arm matching is worth knowing if you buy the RT82: the OM body carries a small removable weight-plate, and Ortofon’s instruction is to leave it in place on a standard arm and remove it on a low-mass one, at which point “the mass of your OM cartridge is now a mere 2.5 g”. What we will not do is compute a resonance figure for either pairing, because the two makers publish compliance on different terms — Ortofon gives the OM 10 as 20 um/mN with no measurement frequency stated, Audio-Technica gives the VM95E as 7 x 10-6 cm/dyne explicitly at 100 Hz — and numbers on different terms do not belong in the same sum.

One more asymmetry in the upgrade story, in the RT81’s favor for once. Ortofon markets the OM range as stylus-upgradeable, and in general terms its OM Series page says so. But its fitment lists are model-matched: the Stylus 10 page names the OM 10 among a long list of compatible bodies, while the Stylus 20 page lists only the 20-series bodies and does not name the OM 10 at all. So the sanctioned path for an RT82 owner who wants more is a new cartridge rather than a posher tip in the same body — which is exactly what the wider supported-weight window is for.

The third deck at the RT82’s price

Fluance’s own comparison chart, printed on both product pages, lists the RT81 at one price and then lists the RT81+ and the RT82 at the same price as each other, one step above it. Most RT81-versus-RT82 arguments are written as if that middle deck did not exist, and it changes the answer.

The RT81+ is the RT81 with three changes: the current AT-VM95E cartridge instead of the discontinued AT95E, an acrylic mat on a damped platter instead of the rubber mat, and three adjustable feet. Its published table is otherwise the RT81’s row for row — same DC motor, same three-point rubber isolation, same 0.2% wow and flutter, same plus or minus 1.00% speed variation, same 67 dB, same 28.2 g arm, same switchable preamp with the same 140 mV line output and the same full bypass.

So the real decision at that price is a fork, not a ladder. The RT82 spends the money on the motor and hands you the preamp problem. The RT81+ spends it on the cartridge and the mat and leaves the mechanism alone. If you want to think of it as arithmetic: a headshell-mounted VM95E kit costs more on its own than the step from the RT81 to the RT81+ did when we checked, so if a VM95E was always the plan, buying the deck that ships with one is the cheaper route to it. And if you like the acrylic idea but not the price, an acrylic or cork mat is one of the least expensive changes you can make to an RT81 you already own.

What both decks do identically

Worth saying plainly, because a comparison that only lists differences implies the rest is a mystery. Both are belt-drive decks with the motor off to one side of the platter rather than under it, which is the arrangement our belt versus direct drive guide explains in full. Both are manual: an auto-stop cuts the platter at the end of a side, but nothing lifts or returns the arm, so if you leave the room you come back to a stylus sitting in the run-out groove. Both give you an adjustable counterweight and adjustable anti-skate, which is the whole reason this pair belongs a class above the fixed-arm automatics — our tonearm balancing guide is ten minutes of reading that decides whether either deck performs as published. Both have a ground terminal. Both play 33 1/3 and 45 only, with Fluance printing “78 RPM — No” on each table. Neither has Bluetooth or USB.

The physical differences that are not performance: the RT82 is a little taller and about 0.9 lb heavier, its feet are height-adjustable where the RT81’s are fixed suspension feet, its headshell is 1.7 g lighter, and it brings a bubble level in the box that the RT81 does not. On an uneven shelf the adjustable feet and the level are genuinely useful; on a solid, flat surface they are a convenience.

The value calculation

Add up what each side of this comparison actually costs to get playing. The RT81 is complete in the box: deck, cartridge, preamp, cable with a ground wire. Its first sensible expense is a current cartridge, not because the AT95E sounds bad but because its maker has stopped selling the stylus that goes in it. The RT82 is complete in the box for anyone who already has a phono input, and is two purchases away from music for anyone who does not — and a phono stage good enough not to undo the motor upgrade is not a trivial line item.

The version of this that costs the least in total, for a reader starting from nothing, is usually the RT81 into powered speakers. The version that ends up the best turntable, for a reader who already has an amplifier with a phono input, is the RT82. And the version that annoys the fewest people in two years is the RT81+, because the cartridge is current, the preamp is there if you need it and bypassed if you do not. None of those three is a wrong answer; they are answers to different questions.

The decision, in one paragraph

These are the same turntable with two different motors and two different cartridges, and the cheaper one has a phono stage the dearer one deliberately does not. If you have somewhere to plug a phono signal, buy the RT82: its published speed figures are the better part of an order of magnitude tighter on one row and a third of the RT81’s on the other, its cartridge is still in production, and its arm is rated for the heavier cartridges you might eventually want. If you do not, buy the RT81 and use the switch — it is the cheapest deck in this range that is honestly finished in the box, and it sits at the top of our built-in preamp roundup for that reason. And before you commit either way, look at the RT81+ sitting at the RT82’s price with the current cartridge already on the headshell, because the question it answers may be the one you actually have.
