I think it is important to be honest with yourself about what you enjoy. I had a phase where I owned a lot of closed back AT headphones, I valued the clarity and detail they had. Their vocal presentation was very forward which I also found addictive. For open backs I went with Stax. I first auditioned and bought the L700 mk 1. It was another step up in detail and clarity, the ethereal presentation was like nothing else I had heard. I fell down the rabbit hole and chased after the top models. I got the SR-009, SR-007 mk II, a KGSShv and an Octave III for desktop duty. I was rollinā.
Realising that my AT cans sounded a bit thin, I went loiking for other closed backs. Enter ZMF. The Atticus and Eikon had been out for a while and now and then a pair would pop up on the used market. I found a set of Eikons not too far away and bought them unheard.
Slowly but surely they started to change my tonal preferences. The AT cans were the first to go, while they still sounded very detailed and clear they were just too thin sounding. They had too lean body and no real bottom end to speak of.
The Stax stayed, because they were open back and technically very impressive. The use case was also different. I mostly used them for pure music listening. The Eikons pulled desktop duty and had to do a bit of everything. Plus, they were frickin Stax. With them I could soar among the highest peaks on mount TOTL. I would never give them up.
Well, not until Zach announced the Verite Closed and threw a monkey wrench into my plans. Here it was, a ZMF closed back with better technical ability than my Eikons. How could I resist? I got in on the Desert Ironwood order list as soon as it opened up.
When I got the VC they soon became my most used headphones. The Stax no longer got much head time. After a while I started thinking that the Stax were not pulling their weight in my setup. I started using them more to see how they compared to the VC over time. I would still say that rhe SR-009 are the most detailed headphones I have ever heard, they are like a laser at finding details in the music. But every time I put them on I was feeling that there was something missing in the music. Going back and forth between my SR-009 and the VC made it clear that the ethereal electrostatic presentation was no longer what I valued for musical enjoyment. Every time I went back to the VC it was a shock to the senses how a headphone could present music with such slam, heft and weight while still retaining so much detail and clarity.
I took a long hard look at my electrostatic gear and decided that we were better of meeting others. I spent a long time searching for and acquiring my E-stat setup, but in the end it wasnāt meant to be and I do not regret letting it go.
So, what do I want to say with all this? This is a hobby that can eat up a lot of time and money. But be honest about what you really use and enjoy. Do not hang onto gear just because it has taken you a lot of effort to acquire it.
