Inside Track: ESD Acoustic

Tony Wainhouse reports direct from the Middle Kingdom on his experience with this Chinese manufacturer's exotic Dragon hi-fi system…

I recently spent some time with China's ultra-high-end audio specialist manufacturer ESD Acoustic, operating in my wife's hometown of Hangzhou City. This green urban jungle is the size of a small country and home to more than twenty million souls. Repeatedly rated as the best commercial city in mainland China by Forbes, Hangzhou is China's internet business incubator – and official venue for the forthcoming 2022 Asian Games.

It's a great time to be living in Hangzhou. Headquarters to Jack Ma's Alibaba Group (Ant Group, AliExpress, Alipay) and other tech giants, it's also a magnet for IT professionals and entrepreneurs. As a seasoned audiophile, I was rather hoping that some of this innovation and technology know-how might have rubbed off onto local audio manufacturers – and was not disappointed.

Arriving at the futuristic ESD Acoustic estate on a Sunday afternoon, we were greeted by a charismatic front man – and ESD loudspeaker designer – Jacky Dai. He introduced his family to me, who were all deeply involved in the presentation. To my delight, my English posed no issue for the Dai family, and I quickly learned that China's high-end audio market is thriving.

His company began as a partnership formed between the late Dr Bruce Edgar (of Edgarhorn USA fame), his long-time audio electronics collaborator, Sam Saye – and Jacky's father, ESD founder, David Dai. ESD is an anagram of the three family surname initials. Early in the partnership, UCLA graduate Jacky Dai – still in his late twenties – was mentored by Bruce, imparting decades of audio design expertise. ESD continues to develop that tech, and current ESD specialities include horn-loaded loudspeakers, active field coil drivers and more.

With its headquarters located just south of Hangzhou's Qiantang River, the entire street block is devoted to the Dai family business. The dazzling campus comprises ESD Acoustic, a health gym, a café, a high-end restaurant, and a Montessori-based kindergarten for up to 380 students. There are outdoor walkways, children's vegetable gardens, water features and large amounts of dedicated parking – a rarity in urban China.

The kindergarten mentioned above boasts its very own full Dragon music system, the set-up that I was here to hear. This costs a cool USD $760,000 and comprises a CD player, solid-state preamplifier, and multiple solid-state, single-ended, Class A, 10W power amplifiers. These drive, via active crossovers, full-range, 114dB efficient, 5-way horn loudspeakers; and multiple solid-state field coil power supplies. Supplying the kindergarten with such exotica was ESD's way of helping to cultivate the next generation of demanding, high-end audiophiles and music lovers.

The Dai family also owns a high-end tea plantation located elsewhere, so I would imagine that this brief account of their business interests is by no means definitive. It is hard not to be impressed by all that the Dai family has already achieved, yet they still have big plans. “Only the best of the best!” explained Jacky as he outlined the Dai family's vision of developing mainland China's first-ever high-end luxury brand. It seems the family plan is well underway.

Rachel and I were privileged to join an audience of around thirty listeners in ESD's 170m2 main auditorium – one of several on-site listening studios – to sample the Dragon, an entire ESD music playback system. This is the flagship and with eight brand-new Dragon owners added this year already, Jacky Dai confirmed that sales results have been explosive. It must be said that these are solid numbers for a system that sells in China for so much money.

NOW HEAR THIS

ESD had prepared a full music playlist, complete with a printed programme for each guest. Our music menu resembled an authentic Chinese dining experience, revealing a penchant for variety and good taste. And apart from one Peking Opera track – perhaps essential, given the local audience – the deep Chinese love of melody prevailed. Before each track, Jacky Dai walked the audience through the music, sharing some of his own personal thoughts and opinions and advising guests exactly what to listen out for.

Waiting for the concert to begin, I had little knowledge about the gear we were about to sample. There were a few clues. An imposing, studio-sized Ampex master-tape machine sat nearby, accompanied by a rack full of unfamiliar components. I wondered if analogue master tapes could be playing? Or would some form of digital platform provide the music source? What about vinyl? I couldn't see a turntable. Obviously, the Dragon loudspeakers were horn-loaded – but that was the extent of my ESD knowledge. Importantly, were the amplifiers solid-state, tubed or hybrid?


Music Programme for the ESD Dragon presentation

I confess that I always approach the latter question with open-minded scepticism. Over the years, I've learned to enjoy all music source formats, but I have really struggled to find a solid-state amplifier that provides long-term musical satisfaction. Despite having enjoyed serious affairs with the likes of the outstanding, solid-state First Watt J2 amplifier by Nelson Pass, other more recent encounters with the latest in solid-state power offerings have had me running from the room. Ultimately, I have always returned to tube amplifiers for what I find is a more dimensional, fluid and natural sound. So, I know that I am hard to please - Rachel, even more so. What to expect from the all-ESD ensemble?

From the opening notes of the concert, the sound emanating from the system was breathtaking. Emerging from its inky-black lair, the big lizard's gentle way belied the power and fury that would soon follow. The ESD ensemble delivered the open and realistically 'live' type of listening experience that eludes almost all domestic listening systems. The sound was effortless, relaxed and with a massive sense of scale and weight – all without a hint of tizz or hardness. Importantly, the performance was devoid of the infamous 'honk' that many experts caution about horn-loaded loudspeakers. The first half of the eclectic concert featured music that was foreign to me but enjoyable nonetheless. Jacky and his team had obviously prepared well for their mostly Chinese guests.

A stand-out track from the first set featured the solo voice of Inner Mongolian Qi Feng, an artist possessing both impressive vocal range and outstanding control. The starkness of the unaccompanied vocal recording bared all, leaving nowhere for the artist, the recording engineers, or the Dragon, to hide. From the album entitled My Date With the Grassland, the song performed – simply named 'Father's Grassland, Mother's River' – showcased haunting vocal virtuosity that tested and fully validated the Dragon's ability to render the extreme range of emotive human tones. It was as if the singer was there with us, in the room.

Perhaps the music highlight from round one was folk music from Taiwan, performed by Chinese vocalist Zhao Peng – considered one of the finest baritones in mainland China. Performing the quirky Grandma's Penghu Bay, Zhao Peng's rich and warm sonority was accompanied by traditional instruments. This type of ethnic fare, featuring random rhythms and unexpected percussive crashes – elements unfamiliar to many Westerners – was awash with exotic tinkles, swishes and thuds. The bending flutes floating magically through the auditorium were particularly memorable, underpinned by the smacking of real skin against real skin drums. This recording demonstrated the system's ability to breathe the original event into the venue.

Midway through the concert, ESD called a twenty-minute comfort stop, and as always, Chinese hospitality was second to none. ESD Founder and family head, the charming David Dai, presented guests with complimentary cups of divine vintage tea. Quite the brew, at over USD $4,000 per pound of leaf. Heady stuff!

Returning to the main auditorium, the music programme took a welcome swing to the West as we stepped through a well-chosen – if commercially thrashed – collection of audiophile favourites. Whitney Houston's remake of Dolly Parton's I Will Always Love You kicked off the second set. And while this schmaltzy chestnut is more than a little dated and worn, there is no denying that the production values – and the late Houston's delivery – are both top-drawer. The Dragon took flight and brought the big tune home effortlessly. Personally, I was deeply touched and again reminded just what a truly gifted vocalist the world lost in 2012.

Following a bit more opera and some perfectly enjoyable Enya, another chronically overexposed radio song took its turn. Aaron Neville's Everybody Plays the Fool sits near the top of a growing list of songs that I could very happily never hear again. In fact, we own the original (mint) Euro LP pressing of this album – so we know how well this music is recorded. Yet, it rarely gets a spin. A far cry from the compressed radio mush that made this track infamous in the first place, the Dragon opened the studio door and redeemed this song with unprecedented intimacy and insight.

From the opening bars, the sense of space was astonishing. The fretless bass weaved and snaked, gently sparring with the scant percussion, revealing new levels of artist interplay. Neville's distinctively lilting falsetto was palpable and the – musically rushed, in my humble opinion – chorus exposed the true complexity of the rich harmonies at play. That the Dragon system was able to illuminate this particular track, despite my radio-jaded ears, speaks volumes. Perhaps I won't sell that LP, after all.

Being asked to sit once more through The Eagles' indomitable 1994 remake of their 1976 hit Hotel California felt somewhat inevitable, but entirely necessary. Like other indispensable test tracks that I've played to death, every split second of this latter-day classic is a known quantity to me. Therefore, to hear this immaculately recorded event on a system of the Dragon's calibre was a genuine indulgence – and one which provided an invaluable reference point. In the opening seconds of the live recording, the audience's applause sounded tangible and present – as opposed to the irritating 'heavy rainfall' impression often left by lesser systems. 

In an instant, we were transported to Burbank, California and took our place amidst the adoring crowd. The familiar opening 12-string guitar chords jangled and shone like steel wires should, in sharp contrast with Felder's opening licks – his instrument clearly sporting a more tactile set of strings. By the time the big conga bass notes entered the fray – with the Dragon distinguishing the differing pitch of each drumhead – my toes were already tapping and my head was swaying. A quick glance around the auditorium confirmed that I was not alone. As expected, the Dragon took wing allowing the boys to check us in, one more time. Nobody checked-out.

One quibble, though. The music volume was set way too high throughout much of the concert for my comfort. Rachel's younger ears also protested during some of the musical climaxes. Such volumes did not seem to bother the other guests at all, who remained comfortable in their seats. Perhaps they were all too polite to quietly cover their ears at the climaxes, as I did? I guess I will never know, but in fairness to ESD, these peak volumes correctly emulated the highly dynamic experience of a live musical event – and enabled the audience to enjoy all of the very quiet passages.

Could any of us really live with listening volumes that realistically reflect a live musical performance? Probably not. But nobody left the auditorium questioning the Dragon's capabilities around control, dynamics and stability at high volumes. In that regard, the system never once sounded strained and certainly never ran out of puff. The good news is that during the break and after the formalities had ended, the Dragon sound proved to be equally dynamic and beguiling at much lower listening levels.

THE RIGHT STUFF

With reference to the Dragon system topology, I was more than a little surprised when I discovered that we had been listening to Compact Disc. Hot off the press, we were also privy to a first listen to a new ESD Acoustic CD entitled Touch The Music. This is an all-digital recording of audiophile pieces which reminded me that digital has well and truly come of age. For those of us who may have forsaken spinning CDs some time ago in favour of ripped or downloaded files – guilty as charged, here – the ESD silver disc spinner is a revelation.

I also learned that the Dragon amplifiers – one 10W amplifier per loudspeaker driver – are of the Class-A, solid-state, single-ended variety. At 114dB efficiency, the Dragon horn-loaded loudspeakers can breathe fire on just half a watt. Thus, 10W provides virtually unlimited headroom. Small wonder the Dragon could torch the room in a heartbeat. The sound gave no real clues around its solid-state engine room; it just sounded natural. Jacky Dai also commented that much of this neutral character stems from the use of switch-mode power supplies. Joining the dots, this is evidently trickle-down tech, following David Dai's considerable time as CEO of Inventronics, one of China's foremost SMPS providers.

Throughout the session, I never lost sight of the fact that we were listening to a music playback system that costs more than the average New Zealand home. Putting that into local perspective, gaining Dragon title is roughly equivalent to buying sixteen brand-new Tesla Model Y cars here in China. A first-world buying decision, to be sure.

The ESD Acoustic Dragon is certainly an ultra-high-end, cost-no-object proposition. Yes, it is priced well beyond what most well-heeled audiophiles would ever pay for a music playback system. That said, for the privileged few who can afford Dragon ownership – and that should include cinemas, theatres and large performance venues – ESD has crafted a system of rare synergy and capability; a system that demands to be heard.

During our ESD visit, Rachel and I were also rather smitten with ESD's Panda series of loudspeakers designs: the 86dB efficient ESD Acoustic Panda (USD $17,000) and the 92dB efficient ESD Acoustic Panda Plus (USD $28,000). Here we encountered a couple of high-end loudspeakers that well-heeled audiophiles can afford. Unsurprisingly the Panda sounded utterly superb. Producing bass that reaches down to a very useful 35Hz, these ESD siblings share some of the magic that infused the Dragon performance – in a form-factor that would be right at home in the typical audiophile listening room.

The deceptively large, standmounting, 2-way Panda loudspeakers are impeccably-built and really are something to behold. Replete with massive CNC precision-machined aluminium inner-cabinet frames and baffles, the design bucks recent trends by incorporating a fully enclosed (sealed) cabinet – my personal preference – and powered field coil drivers, à la Dragon. There's definitely something very good going on with these active field coil drivers.

Not unlike their cute namesakes, these loudspeakers are not active, so the Panda still needs an amplifier. You've also got to plug them into the AC mains to power the active field coils. Available in almost any colour you like, the Panda looked truly stunning in white and should be of strong interest to serious audiophiles everywhere. 

To say that the ESD experience was overwhelming is an understatement. It was easily my finest hi-fi experience in the many decades I have been listening. Tragically, more ESD components were begging to be heard, but we simply ran out of time.

THE VERDICT

ESD Acoustic is a serious and capable Chinese high-end brand that deserves global recognition. Undoubtedly, international reach has been a challenge during the pandemic, but for ESD, eventual worldwide success looks certain. Meanwhile, operating in a city of twenty million souls, located within a province of sixty million, in a country containing a third of the planet's population, I'd say the Dai family business is doing just fine.
