Steinway vs. Lyngdorf: Battle of the High End Audio

Steinway & Sons S-15 Dipolar Loundspeaker

Comparing Steinway to Lyngdorf is a bit like comparing Emirates Palace, Abu Dhabi to The Plaza, New York. Or the Singapore Airlines onboard First Class Suite to Etihad First Apartment. Or even the McLaren 720S to the Ferrari 488 Pista. You get the drift. So, after writing a review of the Lyngdorf MP-40 processor for HTF last summer, I was intrigued that the exclusive UK distributor for Steinway Lyngdorf, Gecko Home Cinema, asked if I would be interested to take on what we might call a ‘best vs. best’ challenge. But the remit here will not necessarily be to identify the finest home theater, as both the Steinway and Lyngdorf systems in this face-off have impeccable performance within their price ranges and, importantly, are made by the same company. Rather, the goal is to pinpoint what audio characteristics, if any, justify an approximate $90k uplift in budget from a $100k to $190k system (at current exchange rates).

The playing field here across two demo rooms is far from level. A full Steinway system (as found in the second of two demo rooms at the distributor’s HQ) employs an “integrated” approach. A P300 2.1 multi-channel processor, for example, must combine with its own-brand amplifiers and speakers to pass a 100% digital signal down through the chain to produce a sound. Steinway’s team refer to the power stage as true digital amplification (TDA), as it rejects any “sound-deteriorating analog conversions”. Peter Lyngdorf adopted these ‘EQUIBIT’ amplifiers to convert PCM (Pulse Code Modulation) signals to a PWM (Pulse Width Modulation) signals, effectively making the amps themselves digital-to-analog converters. The ‘true digital’ nature of the amplifiers, combined with the vibration-free aluminum billets housing the speaker drivers, contribute to an imperceptibly silent noise floor.

Steinway’s deceptively tiny Model S-15 loudspeakers with 92 dB efficiency deploy dipole AER tweeters focusing audio directly to the listening position, with perfect synchronized timing. Four Steinway boundary woofers also boast faultless timing from both direct and reflected sound, with all seats in the house guaranteed the same experience. The boundary woofers receive a low-pass filtered signal at 400 Hz (even though the drivers themselves are linear up to 1.5 kHz), lending further punch and credibility to gunshots and whacking snare drums. Despite the rollcall of formidable technologies that the Steinway system exhibits, the salient point here is that none of the components can operate in isolation.

(It is worth adding that the P300 has optional AES3 and AES67 boards for integration with DCI-compliant servers. Stacking several of these processors allows up to 64 discrete channels or immersive audio ‘nodes’, as found in commercial cinemas. Claus Glaesner of Home Theater Professionals in Los Angeles currently spearheads these exclusive residential projects for SL stateside.)

Lyngdorf, in contrast to the Steinway integrated approach, designs its components to be mixed and matched with others, if desired, and is therefore technically a ‘separates’ brand. The Lyngdorf ‘SDA’ moniker (as in the SDA-2400) means ‘semi digital amplifier’ i.e., driven by an analogue input source and outputting an analogue signal. Unlike Steinway’s true digital amplifiers, the SDA models are what most manufacturers would refer to as conventional digital amplifiers. The Lyngdorf rack, headed up by a MP-60 processor, powers a full array of 300 series M&K monitors and an imposing double stack of three X12 subs either side of the screen. The two side-by-side evaluation rooms at the distributor’s head office near Newbury in the UK represent substantially different volumes (detailed below).Lyngdorf MP-60 Processor and stack of SDA-2400 power amplifiers

No Treatment

One of the most critical points to explain here is that neither the Steinway nor Lyngdorf demo rooms use acoustical treatments of any kind. Acoustically transparent flat black gauze material drapes the steel and concrete surrounding shells and only dark grey carpets run wall-to-wall in both environments. Due to the extraordinary efficacy of Steinway Lyngdorf’s RoomPerfect in-room calibration system, the distributor tore out all traps, diffusers and absorbers after installing both sets of hardware from the Danish brand(s). SL founder Peter Lyngdorf himself insists that achieving a perfect measurement curve in a living room is quite different from doing so in an anechoic chamber. His words might sound counter-intuitive, but with 80% of audio energy in a given room caused by reflected sound – and with the possible exception of a “small amount” of behind-audience diffusion – Mr Lyngdorf says,“Remove everything.”

These facts should play a key role in any decision-making process for those considering building out a truly high-end home theater. The distributor points out that the next time your dealer/installer sneaks a $70k line item for acoustical treatment into the invoice for your man-cave refurb, caveat emptor!

Equipment and Room Volumes

Below are the full equipment lists for each of the two rooms to be compared. The distributor refers to the Lyngdorf space (with M&K speakers) as the ‘Rives’ Room, named after the architect who originally drew the plans, and the Steinway space as the ‘Model S’ Room. The rear wall of the latter is open-backed but still has a pair of shelf-mounted signature Model S dipolar monitors located behind the audience.

The Face-off

As with some other A/B comparison attempts, I stress that if a prosecutor made claims for scientific legitimacy here, they would be immediately thrown out of court. As mentioned, the two Steinway and Lyngdorf rooms are neither identical in volume, build, electronic architecture, or speaker layout. However, I could at least achieve some semblance of a controlled experiment by using the same content from identical Blu-ray decks, and listening at the same levels (11 dB below reference) for all sources. I also selected Steinway Lyngdorf’s ‘Neutral’ voicing on both processors. So, I must rely on my ears to identify any performance differentials, if at all.

Kicking off with two-channel music selections, I ran “Fly on a Windshield” from Genesis’s remastered double-CD The Lamb Lies Down on Broadway in the Lyngdorf room. The MP-60 interpreted the track’s majestic arrangement with studio-like precision and offered up every instrument to the listener for renewed scrutiny. Thunderous rock without missing a trick. Transferring over to the Steinway, the performance was a twinge brighter, but with more refined low-end weight and a little more high-register detail shining through in Peter Gabriel’s vocals. I detected similar vocal highlights from the Steinway on Radiohead’s “Airbag” from OK Computer along with a more defined bass guitar line.Steinway & Sons S-15 Dipolar Loundspeaker

It wasn’t until I spun up A. R. Rahman’s beautifully recorded CD soundtrack for the movie Lagaan that things got a little more interesting. The Lyngdorf/M&K setup delivered a faultless, nuanced and multi-layered performance of the song “Mitwa”, but playing the same piece in the Steinway room was something of an epiphany. Suddenly, rather than listening to an immaculate interpretation of recorded music from the Lyngdorf, the only way to describe the experience from the Steinway was that of a live performance taking place in front of me. It was as if I could point to the artists in their respective positions on the stage, even down to the specific height of the microphones. Strings were full and real and tangible, and the tabla drums utterly vivid. The Steinway also managed to transport a full symphony orchestra to the demo room for my recording of Vaughan Williams’s The Lark Ascending.

Both systems were so competent with film soundtracks, it seems like a crime to invite criticism or differentiation. During the opening sequence of Mission: Impossible Rogue Nation (2015) the Lyngdorf/M&K system created a massive Dolby Atmos soundstage as the aircraft powers up and takes off with Cruise hanging precariously from the aft fuselage. The Steinway, while still replicating the scale of the scene, proved slightly more adept at picking out and earmarking surround effects, such as the clanking of steel restraint braces inside the aircraft just above and behind my head. I was aware of enhanced separation of dialogue, music and effects, and an even more studious ability to make all speakers in the room disappear. That same laser-precision placement of front and rear sound effects from the Steinway was also clear in the tsunami sequence of Aquaman (2018) where debris from the storm hurtles through the room above, below and to the sides of the listener. Likewise, raindrops dripping slowly down the windows of the Ford Explorer close to my immediate left and right in Jurassic Park (1993) was something I was unable to repeat with quite the same dexterity on the Lyngdorf.

Final Thoughts

Okay, if money were no object, I would order a Steinway integrated system in a shot. Done. That was easy. It is ultra-cool to have that name embossed on the same multi-stage gloss lacquer used for the company’s legendary pianos. In terms of performance, you just get the feeling with the Steinway gear that there is nothing standing between you and the source…and I mean nothing. If that gives them a slight edge over Lyngdorf, then so be it, but both systems are rock solid and phenomenal in execution.

I will not pretend that there is anything attractive about the price of these systems, but we all need tech we can dream about. It may be that the wizardry found in the RoomPerfect calibration system will trickle down into more affordable components one day. In the meantime, Lyngdorf Audio is making some of the magic available to less well-heeled clients in the form of the MP- processors and SDA- amps. If you are planning to spend $10k on a projector, for example, then you should definitely be thinking about Lyngdorf for your electronics. Finally, I so appreciate what Steinway Lyngdorf is doing for the audio community. Their products have nothing short of made me re-evaluate what it is I love about music and movies. And that’s saying something.

I'm glad you like these systems - I do too. BUT,

Claiming that you feel like you are at a musical performance while listening to mixed, processed, multi-mono track albums is both impossible and a low bar. In effect you are saying that you can't distinguish a difference from the tracking or mastering studio.

In this case, it probably sounded better. I have heard Steinway/Lyngdorf systems and they were more accurate on zero knob, NCP recordings of acoustic music than "professional" studio monitors from PMC, JBL, Focal, Meyer, Genelec, Dynaudio, and ADAM. The rivals even at polite listening levels are rare - Earthworks, Lipinsky, and Kii - and the Lyngdorf has the advantage of top octave headroom for uncompressed music, which has 18dB peaks above 10KHz and can't be reproduced by a 1" dome tweeter. (this recommends the affordable ADAM alternatives, which also sport a Heil type tweeter)

I realize that reviewers have the problem of saying nice things about all speakers so as not to offend advertisers and readers, but apparently these run beyond your stock of superlatives. To really express how musical they are, you need to get out of audiophile comfort zones and reveal that 99% of the recordings and speakers they listen to fall far short of musical reality. Next time, please spin some discs and files by 2L, Chesky, BIS, Aliavox, or Master Performers - and go to acoustic performances immediately before and after so your ears have a reference.

You joined the forum for no other reason than to post that?

Pardon me, but... Snob Alert!

There are a lot of great recordings, from those labels you listed as well as others, but there's also value in evaluating the recordings that real people listen to on a daily basis as well.

Just noticed this review.

Had no idea that Steinway makes audio (playback) gear... but yeah, something to dream a little on... though it's definitely much more realistic for me to attend excellent concerts sporting their pianos... Not even sure where I could find their gear to audition, despite living in NYC, if I can afford them... Hmmm... ok, there are apparently 2 locations in Manhattan: one their own in SoHo(?), another a dealer showroom amongst warehouse buildings on the west side very near the Intrepid...
