@@joebest6582 Yea you are right, I'm totally nuts thinking most other companies are already chasing that dragon. My man! Thanks so much for informing me! 🤣
Minor correction and a bit pedantic. This isn't the first zmf planar but first ground up planar from zmf since they started with t50 mods, which were planars
Coming from many Focal and Audeze headphones I'm deciding between the Caldera open or closed and Atrium open and maybe closed. I love the LCD-5's but just always want more bass and low end punch. I end up using clear MG's or MM-500 more. I EQ on my RME 2/4 when using the 5's. They sound very good. I wonder what ZMF's would give a good bottom end and still have the details of the LCD-5?
"You can't out-susvara a Susvara." And thank goodness. Don't you people have enough neutral-bright AF headphones? Gonna have to audition an Atrium. Thanks Goldy~
Btw what do you exactly mean by the title 'a step forward'? It suggests, that the Caldera is a step forward to the right direction, which would mean, you think they are an improvement compared to the Atrium. Yet, you seem to prefer your Atrium to the Caldera. What direction would you expect from future ZMF planars then; more like the Susvara or more like the Atrium? Thanks!
3:35 curious why your sub of choice is an SB16-ultra (closed/sealed) instead of a ported PB16-ultra. I assumed the PB16-ultra would be better because it is a larger enclosure and a higher price, but is there a reason related to sound quality why you chose a non-ported SB16-Ultra?
Generally, ported subwoofers have the advantage of being able to achieve higher SPL for a given driver size than sealed, but sealed subs will have better actual SQ due to having less time domain ringing, can have a flatter FR, lower group delay and phase rotation. Generally people describe them as being 'Tighter' and more controlled sounding. If buying for a home theatre system where you want to be able to achieve the maximum SPL for the form factor, a ported sub is probably the way to go. For critical listening applications and hifi, generally a sealed sub is likely to be better. I have two of the SB16 Ultras and for my room two of those is somewhat overkill so the extra SPL of a ported sub would be wasted. I'm maximising for quality and so the sealed sub was the way to go.
@@GoldenSound thanks for the quick reply. Super interesting, thanks for the info. Sounds like I would go for sealed as well then. Do you recommend 2 subs for hifi or critical listening over just 1? Not for extra volume, just for sound quality alone. Usually just one sub would mean that it is placed slightly to the right or left of a wall instead of right in the middle, but since it’s a sub and not a normal speaker, would you be able to tell that the sound is coming more from that left/right if it’s just one sub or would you not be able to tell really?
@@camoturtle18 I would 100% recommend going for multiple subs over one, even if it means getting two smaller subs. Multiple subs are the single most effective way to control room modes and can do so effectively below frequencies that it is practical to address with room treatment. As to whether you should set your subs up in mono or stereo it depends on how low your speakers go and what your configured crossover frequency is. If you are using the subs with bookshelf speakers and the subs are crossing over up around 100hz or something, you should probably set them up for stereo. If you are using full size speakers that already go down to 40hz etc, then there is no localisation information down that low (and sound actually doesn't behave in a typical directional fashion anyway, search for "schroeder frequency" if wanting to learn more), and so you should configure them for mono and position them in the room in the way that provides the flattest frequency response in the bass
Hey Golden! Say you're unlucky enough to be stuck on an island but lucky enough to pick just one of the two (Caldera/Atrium) to accompany you, which one would it be? :)
Just to add to Cameron's feedback on the Caldera's; the Caldera is closer to neutral sounding hp but it pairs extremely well w/ a tube amp which will give you options to add the flavor & color one might desire. I run mine on a Cayin HA-3A tube amp and a Burson Soloist GT class A. I also have a Ferrum Oor + Hypsos but the sound on that pairing is a bit dry and less engaging. The Caldera's are also not very hard to drive as I run mine on med impedance HA-3A and Low gain on the Burson. Furthermore and this is something that is often times missed Zach's design of the Caldera is a Planar driver that sounds more like a Hybrid between Dynamic & Planar driver combined; meaning you get the benefits from both in the Caldera driver which will make more sense upon listening.
I would steer clear of anyone saying that HA-A3 and a caldera is "natural" sounding. Theyre natural sounding if youve conditioned yourself to believe the vivid mode on your TV is the most "natural" because its the most "colourful". Lmao
@@jameskegen6812 I agree and I would steer clear of anyone who can't read enough to be able to distinguish the different between the words NEUTRAL and NATURAL. Lmao I agreed w/ Cameron that the Caldera is more "NEUTRAL" sounding (depending on the amp) but you can change that w/ a good tube amp.
@heyguyslolGAMING NEUTRAL is a technical term and doesn't actually exist as a universal profile because of the interaction between its HPTF profile and our own HRTF. NATURAL, on the other hand, is a perceived experience of something. It is also based on those same factors, but is *conditioned* instead. The caldera on any amp is far from natural as far as any authentic production of the actual recording or instrumentation because, or the human voice goes because its exaggerated, but you've conditioned yourself to believe it is through weeks and months of using it. Your brain simply adapts to it and because of all the other 1000s of factors influencing your perceived experience, none of which are how it actually sounds. That perception is how people think cables sound different even when it technically isn't. It's a powerful thing. Give it a couple years, and you'll be on to the next thing you think is NATURAL even though by its very definition, that couldn't be the case.

I prefer the Auteur Classic to the HE1000 most of the time even though the HE1000 is more resolving. Sometimes a lot of detail is like drinking out of a fire hose, it's just too much. ZMF's tend to strike an amazing balance of having great detail, without going over the top while also having excellent overall tonality, and for a lot of people that's preferred.
"Resolving properties", this is totally invented, every headphone can resolve the entire audible frequency range, the impression that one headphone is "more resolving" than another one is just a fact of different tuning, which can be changed by EQ.
All auditory stimulus comes from how the FR of the device interacts with our HRTF, but the graph snap shot can not tell you that.

This is the reason you can have two headphone, one open, and one closed, or a iem and a headphone have a identical frequency over amplitude graph, yet they will still sound completely different. You cannot eq one headphone to make it sound like another. That is fundamentally impossible. Nothing you will ever say will counter that. These are the facts.
Please go back to amir where he uses non stock pads for his headphone testing and unironically said that pads don't make enough of a difference to effect the reasults even though we have factual evidence that they do.
@@En_Joshi-Godrez Amir just measured this overprized, wonky headphone with the pad he got it with. But the frequency response of this headphone will remain strange, wonky and full of resonances with any pads being used.
@@En_Joshi-Godrez Sure, a waterfall plot entails more information than just the frequency reponse, but usually the FR plot is enough to judge if a headphone sounds good or not. And frequency reponse together with distortion measurements usually tell most of the story.

Of the five pairs of ZMF Headphones I own Golden, the Caldera are my favorite sounding ZMF Headphones!
The Calderas on the DCS Stack was one Off my favorite listenings at the HighEnd this year, also the DCS E3 on the zähl mh1.❤
same here, it was my first listen of the Caldera and the best one :D But on tubes i still have to give the win to the Atriums.

We need more headphones like the E3. DF bass isnt really acceptable from headphone anymore.
Also the susvara has resonance issues from the housing. It isnt a very well put together example of a neutral bright signiture.
No. I'm definitely getting A gradep rsx1 as a weirdo headphone.
