Ortofon Launches the Windfeld Ti Cartridge

by Michael Fermer | Stereophile August 2017 Issue

Ortofon, which turns 100 next year, launched the original Windfeld cartridge nearly a decade ago. Named for cartridge designer Per Windfeld – Who had just retired at age 75, after 30 years with the company – that top-of-the-line cartridge cost $3,400 at the time of its introduction.

Between 1976 and 2006, Per Windfeld oversaw the development of cartridges from the top to the bottom of Ortofon’s extensive line, including the MC 20, MC Rohmann, and MC Jubilee, as well as Ortofon’s many series of models: MC Super, Kontrapunkt, MC Rondo, and the budget-priced OM and Concorde DJ series. In a recent interview, Windfeld said that he figures he’s developed at least 50 cartridge model. I’m glad he’s still going strong, and has lived to see the remarkable resurgence of vinyl.

The original Windfeld cartridge was the first developed by its namesake’s successor, Leif Johannsen, Ortofon’s manager of R&D. It retained many of Per Windfeld innovations found in other Ortofons, including Wide Range Damping (WRD): two dampers of different viscosities clamping between them a small, heavy, metal disc. At the time, Ortofon claimed that the WRD assembly produces ideal motor damping throughout and beyond the audioband, to help produce a linear, unusually extended frequency response and outstanding tracking at a vertical tracking force (VTF) of 2.6gm.

The original Windfeld’s low-mass, high-rigidity generator had a boron cantilever and coils wound with Ortofon’s Aucurum wire – gold-plated, 99.9999%-oxygen-free mono-crystalline copper – onto a precision armature. The claimed results are high channel separation, lower distortion, and better channel balance. A strong neodymium magnet system combined elements of Per Windfeld’s Kontrapunkt and MC Jubilee designs with a Field Stabilizing Element (FSE) inside the magnet system, to produce a linear magnetic field throughout the armature’s movement. The result, according to Ortofon, was a 4 ohm, 0.3mV-output system with lower levels of intermodulation and dynamic distortion.

Though the original Windfeld’s tall, thin, gracefully sculpted body superficially resembled the Kontrapunkt bodies, it was a new design that integrated the threaded headshell mount with the generator’s central inner structure, thus providing a more secure, direct mechanical connection between the generating system and headshell. That Windfeld’s black body was made of a “special alloy” whose specifics Johannsen was unwilling to reveal, other than that it was “highly damped and very hard”. The low-mass, high-rigidity generator system featured a boron cantilever to which was attached an ultrafine-polished version of Ortofon’s now-familiar Replicant stylus, which has extremely low mass and large vertical contact area. The Windfeld was a relatively heavy cartridge at 13gm.

I’ve devoted so many words to the original Windfeld because its replacement, the Windfeld Ti, introduced at last May’s High End Show in Munich, retains many of its design elements. However, in many other aspects the Ti differs significantly, beginning with its central inner structure, which is made of titanium (hence the Ti in the new model’s name) using Selective Laser Melting (SLM), a technology Ortofon first used in 2008, in the manufacture of the revolutionary and still exceptional MC A90. The titanium inner structure flares at the top, creating a plat that’s wide enough to be tapped for the holes for the cartridge-fastening bolts. Integral to that plate’s surface are three carefully positioned contact ridges that precisely couple cartridge to headshell. The black outer body, which incorporates the output-pin block, is machined from stainless steel. At 11gm, the Windfeld Ti is 2gm lighter than the original Windfeld.

Over the past few years, Johannsen has been trickling down the magnet and armature technology he originally developed for the top-of-the-line MC Anna ($8,924), first to the MC A95 and now to the Windfeld Ti. The Anna’s magnet system is designed with carefully optimized geometry and materials that produce consistent flux density and a magnetic field of uniform strength, which Ortofon says result in identical flux density around and within each coil, regardless of its position. This, they claim, preserves dynamics and impulse linearity.

Of equal if not greater significance is that the Anna’s optimized magnet system meant that its polymer-based armature could be nonmagnetic and lightweight. Because the armature is nonmagnetic, when it moves it does alter the magnetic field, which means it can move more freely and without magnetic resistance. Yet the system’s magnetic efficiency is high enough that the number of coil turns could remain low to keep the mass down while still generating an output of 0.2mV. All in all, an impressive engineering achievement.

The MC A95’s armature isn’t nonmagnetic, but it’s made ofan alloy less magnetic than the MC A90’s armature, and with improvements in the magnet system, its fewer turns of wire still manage to produce 0.2mV output. If you want to hear the MC A95 in action driving the CH Precision P1/X1 phono preamplifier, listen to my AnalogPlanet Radio Show devoted to John Mellencamp. Even though the audio has been downrezzed on Soundcloud, the MC A95’s sonic improvements over the MC A90 – as well as the character of the P1/X1 – are easy to hear.

Similarly, the Windfeld Ti’s armature, while not totally nonmagnetic, is far less magnetic than the original Windfeld’s. The Ti’s 0.2mV output is 0.1mV lower than the originalWindfeld’s 0.3mV, and its internal impedance is 7 ohms – 3 ohms more than the original’s. A higher internal impedance usually results from more turns of wire being required to achieve the desired output.

In short, the magnet system in the Windfeld Ti ($4,390) isn’t as strong or as sophisticated as the one in the MC A95 ($6,499). But the Windfeld Ti costs only $600 more than the original Windfeld of a decade ago, and for that you get an SLM titanium body and a more sophisticated generator with a less magnetic armature, the benefits of which should be audible.

Pair Windfeld

Because it outputs only 0.2mV, the Windfeld Ti needs to be paired with a very-low-noise phono preamplifier capable of sufficient gain, whether active or transformer-based. You could try a phono preamp based on current rather than voltage amplification, such as the CH Precision P1 – but if you can afford to spend $30,000+ on a phono preamp, you’re not going to stop at a $4,000+ cartridge.

There’s also MR Lab’s Vera 10 phono preamp, which costs under $3,000. Sadly, MR Labs’ founder and original CEO, Max Rottman, passed away last year, but I’ve heard that the company will continue under new ownership, and I’ll be reviewing the Vera 10 soon, in this column or on AnalogPlanet.com. I ran the Windfeld Ti using both the CH Precision and Ypsilon VPS 100 Silver Edition phono preamps, the latter with Ypsilon’s MC 16L step-up transformer.

With Ortofon’s specially polished Nude Replicant 100 stylus and boron cantilever, setup is particularly critical. Because of its severe profile, which closely resembles that of a cutting stylus, the the Replicant can extract maximum information from the groove – but unless every aspect of setup is performed precisely, especially vertical tracking angle (VTA) and stylus rake angle (SRA), it can sound hard and edgy. I’ve read more than a few reviews of Replicant-equipped Ortofons that said more about the writer’s poor setup skills than about the cartridge itself.

Setting a 92° SRA was easily accomplished with the tonearm close to parallel to the record surface. Setting azimuth using a digital oscilloscope resulted in 27dB (left) and 28dB (right) of channel separation at 1kHz – a few dB better than specified in the Windfeld Ti’s owner’s manual. This was achieved with the cantilever just slightly off from perpendicularity. In other words, this sample of the Windfeld Ti was well built – just what you should expect in a $4,390 phono cartridge!

Windfeld Ti Sound

In my May 2008 column, back when I was still a callow, inexperienced audio reviewer, I wrote of the original Ortofon Windfeld: “The Windfeld surprised me by sounding fundamentally correct with just about every record I played. It couldn’t make a dull recording sparkle, or smooth out a grainy one, but neither did it shine a spotlight on what was wrong. It just seemed to get out of the way.

I’ve heard cartridges with more sparkle on top, and with greater transient definition on top and bottom, both of which can complement and improve certain LPs. But until the Windfeld, I can recall hearing none that produced such perfect symmetry of tonality and texture at both ends of the audioband – without inducing boredom, or a sensation of wanting more of something.”

In the context of what was available at the time I wrote: “You can find lusher-sounding cartridges, particularily in the upper mids; you can find models that sound more dry and detailed, and some that carve out space with greater surgical precision. But tonally and, especially, texturally, I don’t think you’ll find a cartridge that’s more evenhanded and honest than the Ortofon Windfeld, or that reveals more true detail, especially in its ability to quickly settle and move on to the next event.”

However, I also wrote: “The Windfeld fell short only in a slight politeness in macrodynamics that prevented it from punching through during large-scale orchestral swings. But that was more than compensated for by its macrodynamic performance and its ability to catch every last grain of reverberant decay.”

So yes – the original Windfeld had remarkable tonal neutrality, and was perhaps smooth to a fault and lacking in dynamic slam, especially compared to the far more expensive cartridges I named in the review: the Transfiguration Orpheus (the first “explosive” Transfiguration, in my opinion), and the Lyra Titan i, considered by its detractors to be too analytical, with etchy, too-sharply-drawn transients.

The MC A90 demonstrated what could be achieved, sonically, by using SLM technology to create a remarkably nonresonant cartridge body; the MC Anna did likewise, and its nonmagnetic armature added the benefits of extreme macrodynamics while revealing lush midrange textures resulting not from added colorations, but from a reduction in mechanical resonances (The MC Anna was actually too much for the still-excellent Continuum Audio Labs Cobra tonearm – something I didn’t understand until I got the Swedish Analog Technologies arm and installed the MC Anna in it – but that’s another story).

Ortofon brought some of the MC Anna’s technology to the MC A95 to produce what is, essentially, a superior version of the MC A90, dynamically and, especially texturally. Of course, other cartridge makers then put greater efforts into reducing their products’ structural resonances and improving their generators, and eventually it was time to update the Windfeld.

You have to like and appreciate how carefully considered and methodical have been Leif Johannsen’s advances and updates over the past few years, up and down Ortofon’s Exclusive line (the cartridges hand-built upstairs, as opposed to the ones built by machine downstairs). What he’s achieved with the Windfeld Ti, sonically and technologically – adding SLM construction and less ferrous armature – is major, yet the $600 price increase is literally less than nothing when you consider the last decades’s worth of inflation: $3,400 in 2007 is equivalent to $4,067.73 today. So in addition to Ortofon’s top-shelf cantilever-and-stylus assembly, already included in the original Windfeldm you get all the upgrades free – a lot of cartridge technology for $4,390. Yes, back in the real world, $4,390 times four can get you a new Ford Fiesta – but we’re not in the real world here, so drop it! If Ortofon is right about them, these upgrades should transform what was already a very fine cartridge into one even lower in tonal coloration and with greater macrodynamic slam.

Still Sweet Sound

The Ortofon MC A95 was installed on the SAT arm when Leif Johannsen visited, so that’s what he listened to and commented on in the video posted on AnalogPlanet. At first, the Windfeld Ti seemed almost as punchy as the MC A95, while delivering richer mids and thus filling in an area where the MC A95 can sound slightly recessed. After a week or so of honeymoon, a period of blandness set in – transients softened percussion lost its bite. But after some 30 hours the cartridge woke up, and it’s stayed up – as have I, listening many evenings till way past my bedtime.

Of the many great recordings of J.S. Bach’s Brandenburg Concertos, I have four favorites. First is Karl Münchinger conducting the Stuttgart Chamber Orchestra (3 LPs, London CSA 2301), a mint set I copped for $7.98 during the era of “Vinyl is a known carcinogen, get rid of it all now!” (Yes, I know: PVC is carcinogen). I also have the performance by Collegium Aureum licensed from Harmonia Mundi, in a budget reissue (2 LPs, RCA Victrola VICS 6023). The late Nikolaus Harnoncourt plays cello and conducts Concentus Musicus Wien on the original Das Alte Werk black/gold-label edition issued as two separate releases, bought new in 1967 (2 LPs, Telefunken SAWT 9459/60). I also have Jörg Kessler’s ARS “Hear the Music” reissue from, I think, the 1990s. Kessler deserves more credit than he gets for keeping vinyl alive in that decade! The latter two are performed on original instruments; the Münchinger/Stuttgart sounds as if it’s played on modern instruments – the sound is brawnier, and a modern flute sounds very different from a recorder.

I lay all this out to you for two reasons. First is that the Windfeld Ti retained all of the sweetness and lushness of the original Windfeld – something that makes it special in Ortofon’s line of mostly tonally neutral cartridges – which made it supremely pleasurable to listen twice to all four of these sets. Second, while I’m not Martin Bookspan, it does drive me crazy when people say, “Oh, you listen to classical music? I thought you were a rocker”. I listen to a great deal of classical music. In fact, I don’t see how anyone can be an audio reviewer and not listen to it. Speaking of which, if you’re a rocker and want to check out a Brandenburg with balls, try the Münchinger (blueback ffss only).

Tonally and texturally, the Windfeld Ti reproduced massed strings as well as almost any other cartridge I’ve heard: light and gossamer where required, yet also able to dig in and grip. With other great recordings, it also got right the harmonic structure of woodwinds, but it could be slightly soft with brass, cymbals, and other percussion, if less so than some other slightly mellow-sounding but highly desirable cartridges.

I can’t recommend highly enough the Analog Productions reissue of the Sound of Jazz – performances from a 1957 episode of the CBS TV series Seven Lively Arts, featuring Billie Holiday, the Count Basie All-Stars, the Red Allen All-Stars, the Jimmy Giuffre Trio, Jimmy Rushing, and Mal Waldron, and cut directly from the three-track master tape (Columbia CS 8040/Analogue Productions APPR 1098). Think Kind of Blue sound, recorded in the same studio. The reissue can sound a bit edgy through the MC A95 or the Lyra Atlas SL, but it was sweet through the Windfeld Ti, even if the brass lacked some bite. But the degree of smoothing produced by this cartridge was minor. Some might argue that this is what music sounds like, and that the other cartridges are overhyping it. I’m not getting in the middle of that one, but I could turn up the Windfeld Ti, and it rarely, if ever, offended.

The original Windfeld was great for jazz and classical, and especially voices; so was the Windfled Ti, and it added the dynamic slam to deliver orchestral music without making me wish there was more to give on big climaxes. But if you mostly play hard rock or classic rock, you may want transients with more grit and edge on top. That said, if you play rock occasionally, you won’t be disappointed, as you might be with some of the other sweetie cartridges.

But no one will be disappointed by the Windfeld Ti’s reproduction of space: If they were on the recording, this cartridge delivered solid, three-dimensional images on wide, deep, stable soundstages. With a VTF of 2.3gm, the Windfeld Ti tracked well everything I threw at it, especially sibilants.

While $4,390 isn’t exactly pocket change, when you consider the high technology packed into the Windfeld Ti – the SLM titanium body, the boron cantilever and Replicant 100 stylus, the low-magnetic-flux armature – in my opinion, that $4,390 buys you a piece of the highest echelon of cartridge performance for thousands fewer bucks.

While I Have Your Eyes (and Ears)

I take very seriously what gets published in this column. I try to avoid splashy strings of superlatives (but not, obviously, alliteration!) and “best in the world” hyperbole because I know many readers rely on what I write to make big-money purchases. I get their e-mails. I don’t ever want to be wrong, especially when a lot of cash is involved.

So when, for my May 2015 column, I wrote a very enthusiastic review of Swedish Analog Technologies tonearm ($30,000+) – I think it was the first review of the arm published anywhere – I did so only after I was sure that, as I said at the time, it was “the finest, non-sounding tonearm I have ever not heard”. And when I was sure, I bought one: serial no.006. Since then, every so often, SAT designer Marc Gomez has sent me comments from buyers of his tonearm, who write such things as “Fremer was right!” and “You [Gomez] are a genius!”. So far, no one who’s bought a SAT arm has e-mailed me to complain.

The other day, Gomez sent me a photo that I hope will be published with this column: It shows that he’s up to SAT arm #53! That’s not a high number in the big picture, but it certainly is for a $30,000+ tonearm – and represents total gross sales of over $1.5 million!
