After almost buying the HEKS back in september 2023, only to ultimately go for the ZMF Atrium open, I've today acquired a pair of these headphones.
Roughly half a year ago I moved house, which enabled me to buy a high-quality pair of stereo speakers. Consequently, my ZMF AO were receiving no love at all, partially due to a lack of user friendliness to interact with my audio chain. Since these headphones were still worth a (for me) significant amount of money, I sold them and went back to using my old and trusted B&W P9's.
These are, let's say, an interesting pair of headphones. I believe the word 'veiled' was introduced into the english language for the expres purpose of describing these. They were warm, lush and did certain tracks or artists incredibly well, at times almost matching the quality of my ZMF's at stuff like jazz. However, for other types of music the synergy was missing entirely and it sounded, quite frankly, a bit crap. What is worse, everytime I would switch back to my main (speaker) system, I would get a mental whipslash while my brain had to adjust to the different, far more neutral but still warm, sound signature. Thus the P9's also had to go, even though had I had my system far more user-friendly by acquiring a new DAC.
So off I went and started reading and watching reviews of different cans. Since my main system was already so good, I had no desire to spend a lot of money to try and match or improve it. This is why I initially started looking for 'cheap and cheerful' headphones, which led me to the Meze 105 AER. It had some excellent reviews and matched my pricing requirements, so I picked up an almost brand new pair from the classifieds. Unfortunately, these were a bit of a mess. The bass was very poor at some frequencies, timbre was middling and seperation was only good during the more peaceful parts of the track - once complexity started rising, seperation of instruments completely collapsed and it became a bit of a mess. Thus exit the Meze 105.
This put me in a bit of a dilemma, since it seemed that I needed to pay a bit more cash to get a pair of headphones that would be enjoyable to me. But how much more? I started looking at Arya Stealth's and Organics, but I feared the sibilance and treble (I am a little sensitive in that region and even on the Atrium I suffered from it). I started looking at the DCA stuff, both the Aeon Noire X and the E3 look very interesting, but I really wanted to listening to these before purchasing. And especially the E3 was way outside my desired price range. Meanwhile, I also started looking at the HEKS, which had once again dropped in price since last I had compared these to the Atriums (pricepoint at that time was €1800 and they then already represented good value for money). With the current price for a new pair, I was considering pulling the trigger, since I knew how good they sounded (at least I believed that I did) and I never had treble issue's with these. But being a stingy person, I waited.
Two days ago I found a great local classified with a killer price for an almost unused pair of HEKS's, so I pulled the trigger. I'm glad to say they are really as good as I remembered them to be. It feels totally bonkers to me that you can now get these headphones for only double the price of a new pair of Meze 105's. I've seen it commented before in this thread, but it really feels like the community and the wider world is sleeping on the insane value that these headphones now offer. I'm very happy to have bought these and they seem to pair very well with my Violectric V222 amplifier.
Two questions for my fellow HEKS owners:
1. What is the consensus on equalization? I've currently thrown in Oratory1990's target curve and am largely pleased. It tames some treble on song where I struggle with the treble. John Hiat's 'Adios to California' is a great personal test track for me - it's a great song, but the sibilance everytime he sings an 's' is off the charts for me. With EQ it becomes far more tolerable. But on the other hand I've noticed certain instruments sounding a little less natural - trumpets and saxophones in particular lose a little bit of life. So right now I'm a little conflicted - thankfully my DAC allows easy, on the fly swapping of EQ.
2. Padswapping: I've seen Dekoni and ZMF pads being discussed in this thread. Is there anyone that has taken the plunge to buy a pair of these and is willing to share their experiences?
