Spin Doctor #20: The Rega Naia Turntable & Humminguru S-DUO Pro Ultrasonic Stylus Cleaner

To watch as Rega very slowly expands its turntable offerings upmarket requires the patience of a Thomas Pynchon addict waiting for each new tome from the notoriously slow-working and reclusive author. Starting out 51 years ago with just one turntable model, Rega now offers turntables at seven different price levels, plus a few minor variations in between (footnote 1). During the "lost years" of waning turntable and vinyl sales in the 1990s and early 2000s, Rega boss Roy Gandy (footnote 2) candidly admits that the company put little effort into advancing its turntable designs, as sales at the time didn't really justify the investment. Rega had shifted its focus to digital source components, amplifiers, and loudspeakers, and even introduced a tube CD player.

That momentum finally started to reverse about 15 years ago, as the vinyl revival started to kick in and turntable sales began to pick up again. By this point, Rega was a much larger company and was able to leverage its growing reputation to engage with cutting-edge high-tech manufacturing subcontractors. Through these new relationships, they created a test bed turntable called the Naiad that would extend their design philosophies as far as was feasibly possible. I wrote about Rega's early years and guiding principles back in Spin Doctor #6, but in 2009, with 35 years of success behind them, they had reached a point where they had the resources to explore what was ultimately possible, and not just what they could sell to their customers.

In 2017, following seven years of development, Rega announced the Naiad turntable. This was not intended to be a commercial product for sale, but more of a proof of concept, confirming their faith in the lightweight yet ultrarigid approach they had been guided by since day one. The Naiad used a skeletal plinth made from carbon fiber built for them by a F1 race car subcontractor, a ceramic platter, and a zirconium dioxide main bearing created by a British defense department contractor. Gandy says the resulting performance stunned them, confirming that they were on the right track and giving them confidence to develop new upgrades for all of their turntables. In May 2010, the first fruit of this revived faith in their principles was introduced, a new phenolic resin platter for the entry-level RP1 turntable, which had required a substantial investment in new tooling.

While there was never any intention to put the Naiad into production, Rega didn't keep it under wraps, and would proudly demonstrate it to trade visitors at the Rega factory. When the French distributor heard it, he was so impressed that he immediately wanted to place an order for five units, but was told that it wasn't for sale. By that point Rega had spent well into six figures developing and building a couple of prototype units, but after a bunch of arm twisting by various dealers and distributors, they eventually succumbed and explored the possibility of building a limited run. With only a handful of employees possessing the skills required to assemble it, they figured a run of 40 units was about right, matching the number of years the company had existed for at the time. However, they soon discovered that some of the subcontractors required a minimum order of 50 pieces, so that number then became the new production run total. Unfortunately, while they were actually assembling them, they found a few parts that didn't completely meet their standards, so the final Naiad production run was shortened to just 47 units, with each one carrying a price tag of $45,000 in the United States.

The Naiad's high price was the result of some of the design choices that had already been made, when scaling up for production wasn't even under consideration. Rega knew it wouldn't be too difficult to create a more production-ready version, into which they could distill most of what they had learned from building the Naiad. The result is the Naia, where with just a few simple changes, they have managed to undercut the Naiad's price by more than 70%, down to $12,995. That's still big money by normal Rega standards, and more than double the price of the prior flagship Planar 10, but it's still pretty reasonable compared to many other top-of-the-line turntables that shoot for the stars.

The Naia Examined
At first glance, the Naia looks remarkably similar to both the Planar 10 and Planar 8 models that sit below it in Rega's lineup, with all three sharing the same basic layout including what I like to call the pretzel plinth. This skeletal structure is built from a lightweight polyurethane foam core called Tancast 8, sandwiched between top and bottom layers of laminate. While the Planar 10 uses a high-pressure plastic laminate, the Naia steps that up to graphene-impregnated carbon fiber, which Gandy says makes it even stiffer than the Naiad's pure carbon fiber plinth. Everything possible has been done to minimize the mass while maximizing stiffness, including paring down the three supporting feet to minimalist aluminum cones.

Rega says that the one place where higher mass is important is with the platter itself, where increased stability is gained by concentrating the mass and thereby the inertia near the platter's outer perimeter. To achieve this, the lower surface of the solid ceramic platter has a tapered profile that gradually thickens as it goes from the interface with the inner hub, towards the platter's outside edge. Rega has always promoted a felt mat as the best interface between a perfectly flat platter and a less than perfectly flat record. The mats Rega supplies have become progressively thinner over the years, and that thinking continues with the Naia. The exceptionally thin woven cloth mat supplied with the Naia is pure white to match the ceramic platter it rests on, and is supplied by the makers of the Collaro mat I reviewed back in Spin Doctor #6.

Materials upgrades over the Planar 10 can be found everywhere on the Naia, from the dual ceramic braces coupling the base of the arm to the main bearing for even more rigidity at the most critical part of the structure, to the RB Titanium tonearm which despite the name still uses Rega's familiar one-piece aluminum armtube and headshell. The denser aluminum allows the arm to maintain its optimum effective mass, while the ultralightweight titanium that gives the arm its name is used for the bearing structure to minimize resonances. As with all Rega arms, there is no provision for adjusting the cartridge's azimuth or stylus rake angle, because Rega is adamant that this would compromise the structural rigidity that it insists is so critical. They do, however, offer a 2mm shim that can be added at the arm mount if you want to use a particularly tall cartridge.

The review Naia was supplied with Rega's top moving coil cartridge, the Aphelion 2, and I expect most Naias will be delivered with this combination. More than with most brands, I tend to think of Regas as preconfigured packages of turntable, tonearm, and cartridge, with less of a temptation to mix and match components. Sold separately, the Aphelion 2 costs $5545, but when sold with a Naia the combination is $16,995, a savings of $1545 over buying them separately.

Rega resisted moving coil cartridges for a long time, before finally launching the original Apheta in 2005. In the nearly 20 years since then, it has expanded the line to four models, including the top-of-the-range Aphelion 2, which has a boron cantilever and a fine-line stylus. Output is lowish at 0.35mV, and Rega recommends loading the 10 ohm coil at 100 ohms. Tracking force is 1.9gm. One big advantage of using Rega cartridges and arms together is the proprietary three-point mount that positions the cartridge in the headshell at Rega's preferred alignment. Rega says that screw torque is critical when installing its three-point mount cartridges, so a torque wrench is provided for tightening the screws should you need to replace the cartridge.

Setup: When you unbox a new Naia with a premounted cartridge, you'll discover what must be the simplest ultrahigh-performance turntable to set up and get running. The entire process takes about 10 minutes, with no special tools or fancy skills required. As someone who makes a living doing this type of work, I feel a bit like Rega is conspiring to put me out of business!

First you need to ensure that your supporting surface is perfectly level, because the Naia's minimalist feet are not adjustable. Without the platter, the main turntable chassis and arm is shockingly lightweight at around 2.5lb, while adding the platter and dust cover more than triples the overall weight, to just over 10lb. The early pretzel-plinthed Regas came with an outer framework that the plinth could be nestled in, and this allowed for a conventional hinged dust cover. More recently, Rega has abandoned this approach, and the dust cover is now an acrylic sheet that sits directly on the platter, with a raised flap that extends over the tonearm. I suppose this is better than nothing, but it really doesn't provide much protection against small children's fingers or overzealous dust-averse housekeepers. The Aphelion 2 cartridge comes with a small cover that you can slip on to protect its stylus, but as with many stylus protectors, I feel that simply installing it may be the act that exposes the stylus to its greatest peril.

With the cartridge pre-installed at the factory, all you need to do is to put on the arm's counterweight, balance the arm at zero grams, apply the desired tracking force with the dial on the arm, then move the antiskating plunger to the required position. As with all Rega arms, the magnetic antiskating can never be completely turned off, so the arm tends to drift to the right when you're trying to zero balance the arm. Therefore, I find it's easier to use an external scale to set the tracking force with a Rega arm. It would be nice if Rega included its own Atlas Mk.2 gauge in the box, along with a spirit level to help ensure that your shelf is level.

I was about to throw away the original stylus off of my Shure M97-HE when I thought, let me just place the stylus assembly into my Vevor US LP cleaner. With just a 2 minute cycle at 35 degrees Celcius and about 12 hours to let everything dry, it was as good as new. No brushing needed, nothing to be nervous about.
Can't do that to a moving coil cartridge though.

I think it used to be that Rega tables were known for running just a tad on the faster side, which they related to maintaining PRaT, but I may be misremembering.

Nice to see the measured speed is so spot on for this table.

I have always wondered if anyone ever did these measurements comparing speeds with playing a record vs. just spinning. I bet it has been done but I missed it.

If the job is done well by the unit in cleaning the stylus. Shaking a brush or shaking water may accomplish the same task.

So, if the job performed by the Hifi Flux is accomplishing the hardest task of deep cleaning styli, it has succeeded.

If it hasn't, it failed. How it performed it matters only to the long term wear on the cartridge, if any. I would have liked this section to include a comparison, but I get it... space constraints.

Thank you for really reviewing this Humminguru unit though. While it is too much for me to attempt, I could see a specialist or a dealer performing this process- if they offered a warranty or some assurances.

Interesting you mentioned the Zerodust goop! I'll be sure to read the 'ensuing' story that will lead from it! Lol... couldn't resist. I wonder if MF was sued or not thereafter his reporting. I sure hope not.
