The End Of A 35 Year Journey ---Zellaton -The Reference Ultra Final Frontier

Hi Steve,

Exciting times, ahead!

Happy New Year!
 
Older Stereophile reviews showed it.
See https://www.stereophile.com/content/audio-research-reference-3-line-preamplifier-measurements- I think it was Nouvelle Revue du Son that also had 50 kohm load.

Unfortunately currently they only show the 100k and 600 ohm load ones.
I have verified this behaviour in my preamplifiers, but did not keep records of it.

There is a lot more about technical matching than childish thumb rules ...
Thank you. The link provides 1 preamp and the distortion and frequency limits are extremes (minimal in audibility) as indicated by JA.

JL Audio F112v2 specs show 50ohms input impedance, Rel states their subs have, "higher than 100,000 ohms".

Of all the people including myself over decades, I know of only 1 scenario where the preamp had a problem driving amp(s) + subs, and that was a tube preamp that had only 1 pair of outputs and the gent split via a Y connection to connect the subs.

Some things don't require overthinking ...
 
Can I ask what happens to your Alsyvox speaker?

Thanks to @audioquattr joining the team we have 3 distinctly different systems at our disposal.

1) Zellaton Ref - Trafomatic - Zanden
2) Cessaro Zeta - Alieno
3) Alsyvox Caravaggio - Conrad Johnson

It was a long time ago in a Galaxy far away when my audiophile journey began. Ive been in this hobby now for probably more years than the age of most readers of this thread.
Steve, let me belatedly congratulate you on the Ultras. As Steve mentioned, we share a common heritage – for 30 plus years, we both lived in the Wilson ecosystem, with tubed amplification. Steve took the Audio Research & Lamm route, while I took the path of VTL and Tenor tube/hybrid. I took my Zellaton ‘leap of faith’ in in 2022 and have never looked back. From the moment they were installed I never had a moment of doubt, never a moment of buyer’s remorse, and my admiration for them continues to grow.

However, Steve, if you're anything like me I think you're going to run into two big problems. First, when you get down to that last 30 days before delivery, you will spend every waking moment like a kid waiting for Christmas morning - it was painful. Second, when you get the speakers, I guarantee you that you are going to live in your listening room, re-experiencing all of your music. Therefore, if you have projects around the house, I suggest you get them done now.:)

As to the Zellatons, with all of the amazing speaker options, my Zellaton zealotry might come across as over-the-top, bolstered by confirmation bias. Yet sophisticated audiophiles with vastly different high-end systems have also come away just as impressed and some even stunned.

Although this post has done an excellent job describing the sound, let me emphasize three key Zellaton points:
  • The top to bottom, “electrostatic” coherency, and seamlessness. I began my audio journey with Acoustats. Hearing music as a seamless singular whole, back then, was magical as was the original Quad mid-range. Add a sweet extended top end, deep bass resolution, and the power and range to pressurize the room to symphonic and hard rock levels, and you get a tantalizing insight into Zellaton sound.
  • I originally heard the predecessor of Steve’s Ultras, the Reference, in Munich several years ago in an atrium room. I would classify the room as large – maybe 20’ x 40’ x 15’. Listening to familiar music, the low-end was rich, detailed, and powerful. My first reaction was to look for a subwoofer, with none to be found. Over the past year in my room (30’ x 20’ x 10’) I am not only in awe of the visceral power, but with their low-end resolution, the bass exceeds anything that I have ever heard. Nothing else is needed. Add extraordinary tonal color, beauty, spectacular imaging, and the ability to disappear into the music – you’re entering Zellaton heaven.
  • All the above is merely academic but does not address the emotional connection to the music, which is the critical factor for me, and Zellaton nails it. I am fortunate to have some incredible copies of master tapes, and last Saturday we listened to The Best of Bread. When you're listening to music that you've heard hundreds of times and the emotion, resolution, and transparency cause involuntary gasps while listening, and you're left emotionally exhausted and speechless, just staring for minutes after the music ends, then there is something very special happening. The Zellatons connect you to the music.
I've been fortunate to hear some of the very best speakers in the world. I am positive that when you get your speakers you will be in for an amazing journey. Hopefully, I can wrangle an invitation to hear the Ultras!

What a beautiful and eloquent report, Mike! Thank you!
 
Mike

Thanks for adding some very important data points. I too started with electrostatics and what I heard was an emulation of quads in the midrange. What I also heard left no desire to have a sub in the system

I appreciate your input. Well stated

Fantastic description! Sounds beguiling! Would like to hear them someday. BTW, did you ever happen to hear the YS Sounds amplification when you have heard these? I am equally if not more interested in learning more about those! Insanely expensive even by high end audio standards...600K for amp? Their 988 amp looks like a sleek Boulder 3060...and appears to be nearly the same volume in size.

Somehow there is something about the sound of all of the videos with the Zellaton and YS Sound that intuitively makes me want to know more about both the YS Sound and Zellaton.

Mike, a little off topic, but you mention that your room measures 10 x 20 x 30, which is sort of the worst case scenario for stacking room modes (a rectangle where H, W, and L are multiples of each other) leading standing waves. Since you are apparently getting great sound on the space, could you share what room treatments you have implemented to address that issue?

Sorry about that .... I did not remember the exact room dimensions, so I just put approximate numbers off the top of my head. The 30x20x10 are just ballpark numbers. The room was custom designed by ASC (Acoustic Sciences). When designing the room, we took multiple size iterations and ran them through room optimization software to get the best dimensions possible for my space, in order to minimize room modes. ASC then brought in equipment and took sound measurements, analyzed it, and presented multiple possible room designs. The original picture of my room is on the ASC website homepage.

I chronicled the building of my room in a rather lengthy article on 6moons.com. That was 15 years ago, so the equipment and some of the tube traps have been upgraded, but the room construction remains unchanged. https://www.6moons.com/audioreviews/theroom/1.html

really nice room. Congrats! by the 10 by 20 by 30 works really well
 
I really enjoyed reading the comments and while it’s tempting to delve into everything Zellaton, I’ll stick to a common theme of all those who admire Zellaton: the love for Quad ESL-57’s and my own journey to Zellaton.

I think there’s a pretty compelling reason why Mark Levinson chose the 57’s in stacked glory, as his go to speaker in the early days. And to see a current and thriving restoration culture for Quad, is further validation of their charms. For me personally, despite the (get its claws into my soul) midrange, they just left we wanting in terms of meat on the bones weight along with dynamic prowess. The closest I got to Nirvana was an original untouched set combined with Gradient custom subs, designed for the 57’s which served as an elegant base as well.

The evolution from Quad to Zellaton manifested through a few speakers which used the early Görlich drivers, namely PAWEL/Ensemble PA1, Expolinear, Terzian and Symphonic Line RG5. Like all of us I’ve acquired way too much audio ending up purging the gear which no longer excites me;)
But the one speaker that I kept is a very early PA1 example with unique excursion wide bridge foam (not rubber), Hiquphon tweeter and the famous Kef passive radiator. These replaced my Quad yearning with similar open window qualities, but with even greater speed, upper air registers and power (in most moderately sized rooms).

But the PA1 is now almost 40 years old, perhaps why I got so excited the first time I heard ZELLATON, which included not just the famous midrange, but a bass woofer and tweeter combined. The seamlessness, coherency and naturalness left me speechless, accounting for my continued passion after 14 years of being with the brand. Finally I’ve found my modern day Quad, albeit without any limitations.

Many don’t know that Manuel Podzsus, Zellaton partner today, is the grandson of Zellaton founder Emile Podzsus. I’ve always been in awe of how Manuel has successfully preserved his grandfather’s legacy.

Makes sense, thanks for the additional context. Love the couch vs a single chair in the sweet spot too!
 
Here is an ad from the 1930s!! of the original Plural model, which is why the current version is called the Plural “Evo” along with ZELLATON founder Emile Podzsus and his wife at a trade fair in the 1950s - and his grandson Emile Podzsus today

Three or four years ago in Munich, I heard the Zellaton Reference Speakers powered by YS electronics. The problem is that all the equipment was unknown to me. I had no baseline to separate the sound of YS from Zellaton. Overall, the sound was mesmerizing, with a clear YS/Zellaton synergy.

After getting a grasp on the amazing transparency of the Zellaton speakers, I can tell you that they let the character of the upstream electronics shine through. It's easy to hear the subtle, and not so subtle, differences in any electronics that I've had in my system with the Zellatons. So, in retrospect I can only characterize the YS sound with very broad-brush strokes. They are extraordinarily musical, with a very refined natural sound, and clearly produce very realistic imaging. And you are right, they are very, very expensive. Gideon Schwartz is a fan of YS and can offer a much greater insight.
