When I do a review, I like to take notes on my phone as I am listening. I usually listen late at night in bed or early morning in bed. No disturbances and the focus is just on the music. I then take these notes and clean them up and post randomly on the Head-Fi thread for the item. Each post is usually something specific I am discovering that I think might be of interest to others. I post as I am going along especially when it is an IEM or HP that has not been released yet. There is a high interest in the information since not many people have heard the item yet.
I then take all the posts and clean them up and add to them and make them coherent and flowing for review purposes. I do sometimes straight forward reviews or I develop a fictitious character with very specific odd traits and use them as my Muse for an interview method of getting the pertinent information to the reader.
I only review items of interest to me. And I do it for fun. I enjoy the hyper focus needed to put together a review that is hopefully of value to others.
I did an Atticus/Eikon Review for fun awhile back. The Caldera Closed is bringing back memories of that review.
I find that the ZMF house sound is all the way through all HPs. I have owned all of them except the Bokeh I also would like to amuse myself and overgeneralize big time and say that the ZMF HPs fall into two camps. There is the increased detail, clarity and a slight sub bass bump camp of the Eikon/Auteur and Atrium Closed and Open versus the higher resolution, fun with darkness and a slight mid bass bump of the Atticus/Aeolus and Verite Closed and Open camp.
The open and closed of each version stay within one of those camps which makes sense. The closed and open versions have the same exact driver.
For me the Caldera Open and Closed are the first ZMF headphones that do not stay within the same camp. From memory for me the Caldera Open was about the clarity and detail. Very quick. I also had the Audeze LCD 5 at the same time as the Caldera Open and the Caldera did lean (not all the way thankfully) in the direction of the LCD 5 intenseness and clarity of notes.
For me on the other hand the Caldera Closed is in the resolution/darkness and fun camp. That said of course the CC being a Planar driver has for sure a good amount of clarity and detail. What is unique with the CC is that it really has a wonderful “fun” sound for being planar.
Someone correct me if I am wrong, I do think the CO does not have a filter system while the CC does. I am guessing that this allowed Zach to play around with the tuning of the CC to be able to add some fun darkness which the CO has less of.
Those are my thoughts for the moment.
