ACOUSTIC SIGNATURE MERLIN NEO TURNTABLE AND TA-500 NEO TONEARM REVIEW

Stuart takes a listen to this neat-looking and beautifully engineered turntable from German brand Acoustic Signature, which represents the company’s entry point into their extensive vinyl ecosystem.

Founded in 1996 in Süssen, Germany, Acoustic Signature has spent three decades concentrating on one thing: the design and manufacture of analogue replay equipment – that’s turntables to you or I. What began with the company’s first high-mass turntable and Tidorfolon bearing has grown into a range of turntables, tonearms, cartridges and accessories that are now distributed worldwide; indeed, if you are at the Hong Kong show this week, you will be able to see the MERLIN NEO in action. More recently, the introduction of the NEO series marked a complete redesign of the company’s product line, bringing together several of its latest engineering developments into a new generation of products that aim to be more affordable and accessible.

Acoustic Signature is still a privately led company, with founder Gunther Frohnhoefer continuing as CEO and Head of Development alongside CEO Jacqueline Frohnhoefer. Supporting them is a relatively small team of 28 employees that includes engineers, electrical technicians, precision machinists and goldsmiths. The industrial design of the NEO range was developed in collaboration with Burkhard Schlee.

Manufacturing takes place at the company’s headquarters in Süssen, where Acoustic Signature maintains a high level of in-house production. Components are designed using CAD/CAM systems before being manufactured on CNC machinery, while parts not produced internally are sourced from specialist suppliers within the surrounding region rather than through low-cost overseas manufacturing. Having visited the factory several years ago, I really like this “philosophy” of using local specialists rather than the reliance on Far Eastern manufacturers and suppliers.

Every turntable and tonearm is assembled by hand and individually tested before leaving the factory.

The company’s continued investment in production is reflected in recent additions to the factory, including the installation of a 22-ton, five-axis precision milling machine to expand its in-house manufacturing capability. As well as the obviously high-tech aspect of the factory, one thing I recall from our visit was a clever use of Lego bricks to monitor the number of parts that go into building their turntables – low tech, but a highly effective and simple stock control system. However, I’m damned if I can recall the details other than thinking “Wow, that’s very clever!”

Acoustic Signature’s engineering philosophy centres around precision manufacturing, long-term durability and quality control. That confidence is reflected in the warranties offered across the range, with turntables covered for fifteen years and tonearms for five years, subject to registration. Alongside laboratory testing, new developments are also evaluated by professional musicians and sound engineers before entering production.

The Merlin NEO reviewed here sits towards the more accessible end of the company’s turntable range, but it incorporates many of the same engineering principles and technologies found throughout the wider NEO series. Supplied complete with the TA-500 NEO tonearm, it provides an opportunity to see how Acoustic Signature’s approach translates into its more affordable package.

The NEO Merlin was first introduced at the Vienna High End show earlier this year

I think it’s worth looking at the technical specs and design “philosophy” of the turntable and arm as separate entities, though the actual review will treat them as one unit.

Acoustic Signature Merlin Neo Turntable and TA-500 Tonearm review

BUILD AND FEATURES OF THE MERLIN NEO TURNTABLE

The Merlin NEO is the successor to Acoustic Signature’s original Merlin turntable, first introduced in 2016. It is supplied exclusively as a complete package with the company’s TA-500 NEO tonearm, combining several of Acoustic Signature’s core engineering technologies in a belt-driven, mass-loaded design.

The turntable uses a belt-drive system with electronic speed selection for 33⅓ and 45rpm, with speed changes made via a switch on the external motor unit. Fine speed adjustment is also provided; I’m never entirely sure why fine speed adjustments are included on turntables other than if the platter somehow spins “off” 33 or 45 RPM, which you would certainly hope that a turntable would not do. Power is supplied by an external multi-voltage power supply compatible with 100–260V AC, so there’s no fannying around should you decide to move country.

The 300mm platter is machined from anodised aluminium, measures 34mm in thickness and weighs 5.8kg. This sits on a one-piece aluminium chassis, also 300mm in diameter, giving the complete turntable dimensions of 474 x 318 x 140mm and a total weight of 15kg.

Acoustic Signature employs its CLD (Constraint Layer Damping) construction within the Merlin NEO. The chassis is manufactured from a comparatively soft aluminium alloy, while the platter incorporates bitumen damping, with the aim of reducing unwanted surface vibrations.

The Merlin NEO also incorporates the company’s Level 1 AVC (Automatic Vibration Control) system, designed to minimise vibrations generated by the motor before they can reach the playback system. The AVC system forms part of the digital motor control electronics housed within the Merlin NEO’s separate external motor block. These electronics are crystal-stabilised and control both the power supplied to the motor and the rotational speed of the drive system. Separating the motor and its control electronics from the main turntable chassis provides physical isolation, while AVC addresses vibration through the motor’s electronic control. The intention is to produce stable platter rotation while reducing the amount of motor-generated vibration entering the rest of the turntable. On the Merlin NEO, Level 1 AVC works alongside the CLD chassis and platter construction and the DTD bearing as part of the turntable’s overall approach to controlling resonance and maintaining consistent rotation.

The Merlin NEO uses Acoustic Signature’s DTD (Dura Turn Diamond) bearing assembly, which supports the main platter and forms a key part of the turntable’s drive system. The bearing incorporates a diamond-coated spindle and is designed to provide a high degree of precision, rigidity and durability. It is also specified as maintenance-free, with the intention of providing consistent performance over the long term without the need for routine servicing. Supporting the Merlin NEO’s 5.8kg aluminium platter, the DTD bearing is designed to provide stable, accurate rotation while offering the robustness required for long-term use.

The Merlin NEO is supported by three height-adjustable aluminium feet incorporating gel damping, allowing the turntable to be levelled while providing an additional degree of vibration isolation. A three-point levelling system makes so much more sense to me than a four-point system as it’s just so much easier to set and forget.

The turntable is available with either black or silver anodised finishes for both the chassis and platter. As supplied, the package includes the Merlin NEO chassis and platter, the external motor unit and power supply, the TA-500 NEO tonearm with its counterweights and anti-skating weight, an AudioQuest Golden Gate phono cable, the drive belt, turntable mat, setup tools and the accompanying instruction manuals.

Acoustic Signature provides a 15-year warranty for the Merlin NEO, which is, I think, quite extraordinary.

BUILD AND FEATURES OF THE TA-500 NEO TONEARM

The Acoustic Signature TA-500 NEO is the standard tonearm supplied with the Merlin NEO turntable, though I’m informed that it’s not avaialble on its own. It is a 9-inch design that is manufactured in Germany and built around a rigid, low-resonance construction using high-quality materials throughout – it really does look very wel put together!

The arm has an effective length of 239.3mm and a mounting distance of 222mm from the pivot to the centre of the platter. Effective mass is specified at 10g, with a total weight of 349g and an overhang of 17.3mm. The supplied brass counterweight will allow for cartridges weighing between 6g and 16g, while an additional counterweight is included for use with heavier designs. That pretty much covers al the cartridges that we have to play with.

The TA-500 NEO uses a dual-layer carbon fibre armtube that has been chosen by Acoustic Signature for its combination of rigidity and damping. This is paired with a stainless steel tonearm axis and cardanic precision ball bearings, providing low-friction movement across both planes of operation, and it certainly feels very smooth when handling it.

Internal wiring is studio-grade Mogami copper, with the arm supplied complete with an external Audioquest 5-pin copper phono cable terminated with RCA connectors.

Cartridge setup is aided by adjustment for vertical tracking angle (VTA), azimuth and anti-skating. The TA-500 NEO uses the standard Rega-style mounting arrangement, with an SME-style mounting option available which will be good news for those looking to add this tonearm to their existing turntable set up.

The arm is finished with an anodised silver body, and the carbon fibre armtube retains its natural appearance. Acoustic Signature also includes an accessory pack comprising the brass counterweight, an additional weight for heavier cartridges, an alignment template, the required setup tools, the Audioquest phono cable, and an instruction manual that is pretty easy to follow and well written.

Overall, the MERLIN NEO and TA-500 NEO are a really cool-looking turntable and tonearm package that suggests German precision and engineering prowess. I’d certainly be very happy to have the MERLIN NEO sat atop our HiFi rack, though I’d have liked there to be a cover of some kind included in the package to stop it getting dusty.

Packaging is obviously very good and robust!

SET UP AND USE

Getting the turntable out of the double-boxed packaging was very easy, and, really usefully, there is a diagram on the inside of the box to show you how to repackage the whole lot – I cannot underemphasise how useful this is, and I think it is something all manufacturers should include, especially for reviewers.

Starting from the top layer, you get the instruction booklet and a pair of white gloves (everything has a pair of white gloves included these days), then you remove a layer of packaging material to see the motor, tonearm, cable, tools, and a 30th anniversary recordA. The bottom, and final layer, reveals the chassis of the turntable and the platter. All very well thought out and protective.

One thought that does come to mind is that the turntable and tonearm could come with a fitted and fully set-up cartridge for consumers, given that Acoustic Signature produces a full range that starts at about 630 Euros. Perhaps their thinking is that this leaves the consumer to make their own choice, but including one would further tie people into the Acoustic Signature ecosystem with an obvious upgrade pathway. The review sample was actually supplied with Acoustic Signature’s MCX1 moving-coil cartridge. Built around a CNC-machined, resonance-optimised aluminium body developed using finite element design principles, the MCX1 features an elliptical stylus and copper coils. It produces a 0.55mV output, has a quoted frequency response of 20Hz-25kHz (-3dB), weighs 12.2g and has a recommended tracking force of 2.3g. Recommended loading is 100 ohms, with channel separation specified at greater than 21dB. Acoustic Signature describes the MCX1 as a suitable partner for its NEO tonearm range, including the TA-500 NEO supplied with the Merlin NEO – again, I’d likely offer it as an option for paying customers.

Over and above arm and cartridge alignments, setting up the turntable and arm are relatively easy, and the instructions are good. Pop the spindle into the appropriate hole on the chassis, place the centre of the motor unit so that it’s 212mm from the spindle, pop on the mat, attach the power supply to the motor unit (I noted there was a good length of cable here), attach the rubber belt, fit the tonearm cable (top tip: do this before assembling everything else), plug it into your phonostage and away you go. As mentioned, the turntable came with a 30th anniversary record clamp that is of the locking variety, and I liked this very much. If you are buying from a bricks-and-mortar dealer (I highly recommend you do), then they should come out and set this turntable up for you. I’m relatively experienced in turntable setup, but it’s not for the faint-hearted novice. All told, from opening the box to having music took me about half an hour.

The speed change is a case of flipping the switch between 33, off, and 45, but there is a slight noise from the motor when it’s spinning – inaudible when music is playing. This was largely cured by pulling up slightly the spinning pulley doodad on the motor so it wasn’t rubbing against the body of the motor – not totally eliminated, but mostly gone.

I guess it’s worth saying what I expect from a turntable before moving on to publishing my notes from my listening to this combination. A turntable should spin consistently at the selected speed; that speed should be accurate; no noise/vibration should be transmitted from the spindle or motor to the stylus; and the tonearm should not add resonance or noise to the system. Achieve all the above, and all that a record player does is allow the stylus to track correctly in the groove, pick up all the information in that groove (and only that information), and allow those things to happen whilst not introducing any noise into the system from its own operation. All that seems like a relatively easy task…if only it were that simple.

SOUND QUALITY

I do a lot of beat mixing, and so I’m fairly sensitive to speed variations in music anyway, but piano is the long-established acid test for hearing if a turntable is spinning the record at a consistent speed. With this in mind, I popped on Monk/Trane by, surprisingly enough, Thelonious Monk and John Coltrane. If speed is out, piano (and sax) will sound warbly and just wrong. I’m pleased to report that the Merlin NEO spins at a consistent speed, though I’d have been surprised and disappointed if it hadn’t. Although I’m not a huge fan of jazz music, I did actually end up listening to a couple of sides of this record and thought the Merlin NEO presented it very nicely indeed, with a particularly strong representation of the recording space and staging of the instruments. I started out listening closely for any speed variations the turntable introduced into the experience, but ended up enjoying the performance in and of itself; there was a particularly live feeling to listening to the record, with me loving the contrabass and lower registers of the piano. I could have closed my eyes and been in New York at the Five Spots Cafe whilst listening to this, though it is a studio album.

Changing tack just a tad, I put on our much-played copy of the half-speed master of John Martyn’s Solid Air record, which I still maintain is one of the best cuts of one of the best audiophiley records out there. I wasn’t disappointed! Yes, our Technics 1200G with the Ortofon MC 90X mounted on it has a tad more finesse and pulls a smidge more detail from the grooves, but that didn’t get in the way of my enjoyment of this record played on the Merlin NEO with the relatively inexpensive MCX1 moving-coil cartridge that came bolted onto the review sample of this turntable. I was again drawn to the sounstaging on this record, but also the detail and nuance in the instruments, particularly on the end of “I’d Rather Be The Devil” where the track breaks down into a “dubby” kind of instrumental. I really got drawn into the effects and space created; not something that always happens, with some turntables leaving this section feeling a little flat. I guess what I’m going to say next is very subjective, but I certainly felt myself relax into the recording whilst listening to the second half of this record. The Merlin NEO, for the most part, got out of the way and didn’t enforce a particular sound character on the recording, in turn allowing me to enjoy the musical performance for what it was, without looking to analyse it to the nth degree.

Thus far, the Merlin NEO is doing a great job at doing what it’s supposed to be doing. I do reckon that popping on a cartridge with more finesse would certainly reap benefits, and I think that Acoustic Signature’s decision to not bundle MCX1 cartridge in the commercial package is a sensible one, given that a prospective buyer can audition several cartridges from the company’s range or use their preferred cartridge from another manufacturer. The Merlin NEO and TA-500 NEO will certainly take a cartridge further up in price.

I put on Sterolab’s Emperor Tomato Ketchup (Expanded Edition) and was again impressed with what the Merlin NEO brought to the table. Vocal layers were well separated and distinguishable in the mix, soundstaging was very good, and everything was coherent, present, and correct. However, listening to this record, I was specifically drawn to the weight and heft the Merlin NEO allowed to come to the fore. I do think our Technics has a more authoritative presence when playing this record, but we’re splitting hairs to a large degree – if you can split hairs to a large degree. That weight I mention isn’t the turntable adding bottom end bloat to the recording; rather, it’s allowing the lower registers to feel as they should without overpowering the rest of the stuff that’s going on in a song. I played one side of this record with and without the Grip/clamp (Grimp?), and I do hope that it’s included in the package as it adds a small degree of gravitas and solidity to the music

QUIBBLES

There is still a bit of noise from the motor when the turntable is spinning, but that’s not heard when there are records playing.

There is no cover in the package, which might mean the turntable gets dusty.

CONCLUSION

I really enjoyed the Merlin NEO and TA-500 combo and think it is a very accomplished spinner that fulfils all the things I want a turntable to do. It adds very little of its own character to the music and kind of gets out of the way, allowing you to enjoy the music as it was intended, but I do think our 1200G betters it in some indefinable way. However, I do know that some folk prefer a belt-drive turntable, and with that in mind, I think this turntable will please a lot of people – I certainly really enjoyed listening to my tunes on it.

Would I buy this turntable? Had I not gone down the Technics route, yes, I would certainly have this on my list of turntables to explore at around the €4K mark. It looks fab, is relatively easy to set up, a doddle to operate, and it looks a lot better than the standard boxy offerings.

The turntable and arm will take more expensive cartridges, and I think this is a strong selling point. You can buy this turntable, bolt the

With all this in mind, I’m giving the Merlin NEO a high five-heart award. Had the motor been absolutely silent, I’d have given it our top award as I think it offers an excellent sonic presentation allied with pared back but quite striking looks. \

If you have four or five grand to spend on a turntable, this needs to be on your list of must-audition spinners.
